B. CONDITIONS OF APPLICATION

I. PROVINCES OF NAM DINH, THAI BINH

A. Winter – Spring crop

a) Seasons: Winter - Spring mainly using short-term varieties of rice, cultivation period in late spring.

Landmark time of safely flowering rice from 01/5 to 15/5 is used as a basis to calculate the time of sowing varieties suitable for each variety and each rice season. General direction is a neat arrangement at each period, in each locality, each period, focusing on sowing rice seed in about 07-10 days, in particular:

- Period of early spring sowing from 15 to 20/11, Spring of the main crop sowing from day 5 to the day of 15/12, transplanting from 20/01 until 10/02.

- Late spring period concentrated to sow rice seed after cold spell from 20/01 until 10/02. Focus on transplanting rice after commencement of spring on 10/02 to 25/02, ending transplanting of spring rice prior to 28/02.

Sowing rice seed: from 10/02 till 15/02;

* Orientation of cultivating rice varieties:

2. Summer - Fall crop

a) Season:

- Summer – Fall season:

The concept of arranging the Summer - Fall production season is "as soon as possible" and to ensure the requirement to avoid flooding at the end of the season, so it should be based on the flowering time of Spring rice to produce seeds and it is better to produce seeds of Summer - Fall when Spring rice flowers about 10-15 days. The layout of the season, selection the variety structure must ensure the following requirements:

+ The flood running Summer – Fall region: Harvest prior to 05/9;

+ The intensive farming Summer – Fall region: Harvest not later than the day of 15/9.

- Season Crop: Ensure the harvest duration as follows:

+ Early Season: Harvest in September;

+ Main crop season: Finish the transplanting before 10/8.

b) Take care, fertilization and pest control are similar to the season in the northern provinces (Nam Dinh, Thai Binh).

III. AN GIANG, DONG THAP PROVINCES

An Giang and Dong Thap have some similarities in terms of rice production. This process is most applicable to both provinces.

1. Season

a) Winter – Spring season: starting from 26/10 to 31/12;

b) Summer – Fall season: starting from 20/03 to 10/5;

c) Fall – Winter season: starting from 25/6 to 30/8.

2. Land preparation

The field surface must be leveled flatly, made drains and cleaned up the weeds before sowing, transplanting.

a) The Winter – Spring season: After the Summer – Fall rice season is harvested completely in the 2-season land, the land is plowed until the water recedes, then it is lifted, leveled; and for the 3-seasons land, carry out to prepare soil similar to the Summer – Fall season after Fall – East rice is harvested.

b) The Summer - Fall season: After Winter – Spring rice season is harvested, plough the soil loose before sowing (minimum plowing depth is 20 cm) and dry soil for at least 2 weeks.

c) The Fall – Winter season: After the Summer - Fall rice season is harvested in the 3-season land, soil preparation measure is similar to the Summer – Fall season.

3. Seeds preparation

a) Seed selection: Select the rice varieties in the list recommended by the Ministry of Agriculture and Rural Development from time to time and with white rice quality meeting high quality requirement by the prescribed standards.

- In the principle of seed structure in each season, it is arranged 3-5 top varieties to be high-quality rice varieties, with an area accounting for over 15% of the production area in a season, and arranged 2-3 additional varieties to be the one which are adapted to conditions of local farming but required to be continued monitoring on a large scale. Most are few-day rice varieties with growth duration from 90-105 days. The rate of top rice varieties may vary according to each season;

- It is arranged by an order from high to low rates of rice varieties often used as follows: IR 50404, OM 4218, OM 2514, OM 2517, JASMINE 85, OM 5472, OM 4900, OMCS 2000, VD 20, VND 95-20 and Nep;

b) Quality of seeds: rice varieties must have high uniformity, not mixed with weeds, grass and other varieties of rice.

4. Sowing density

Depending on variety, season, field surface flatness and drainage capabilities of each field plot to determine seeding density, appropriate seeding density is from 80kg - 120kg/ha. It should sow by row seeding tool in the places where conditions permit.

5. Soak of seeds and seed treatment

Seeds are soaked directly into the saline solution of 15% concentration within 15-30 minutes, then pick up the imperfect grains floating above, the remaining sinking part shall be taken out to wash and soak with clean water for 48 hours, keep carefully for 24 hours until the seeds germinate. Then proceed to sow with row seeding tool.

6. Fertilizer

a) Principles of fertilization for rice: to fertilize by the plant needs at time of growth (rise seeding, tillering, rice flowers); fertilize the correct dosage; not to fertilize in excess of nitrogen. Fertilization period for rice can be divided into 3 main batches: Batch 1: from 7-10 days after sowing, Batch 2: from 18-22 days after sowing, Batch 3: from 40-45 days after sowing.

* Note:depending on growing conditions, season, time of growth of rice variety being cultivated to reduce the time of fertilization.

Particularly for land cultivated 3 seasons in many years, it could be added 20% of total amount of nitrogen, and should be added organic fertilizer for soil improvement.

Use the leaf color reference sheets to control the excess of nitrogen in the last 2 batches of fertilization.

b) The time and dose of fertilizer:

- Basal fertilizing: before sowing. Acidic soil should be fertilized Van Dien  fused phosphate (16% of P2O5) from 100-400 kg/ha depending on the acidity of the soil, to lower acidity right from the beginning, the roots will grow better;

- Fertilization for the first time: 7 - 10 days after seeding (NSS), fertilize according to the following table, depending on season and soil type.

(Note: it should observe rice flowers to fertilize for the paddy fields to develop better)

After fertilization is made, then retain water until rice are waxy (from 60-70 days after sowing) because at this stage if the fields are lack of water or dry, rice will be vulnerable to be flat.

* Note:blast, yellow leaf, Banded disease, flat grain, sheath blight, Brown planthopper.

- Fertilization for Fall – Winter season can apply the formula similar to the one recommended for doing in the Summer – Fall season.

Particularly for three-season land cultivated many years, it could add 20% of total nitrogen, and should add organic fertilization for soil improvement.

Depending on variety and soil conditions of each specific region, it can be changed the amount of fertilizer for suitableness to achieve the highest efficiency and can be used super phosphate, other compound fertilizers such as 20-20-15 , 16-16-8, ... to fertilize rice, but it is required to ensure the right amount of pure fertilizer;

If soil is catch alum (the fields have pH <5), it should take measures of irrigation to get rid of alum, reduce alum and add fertilizers to help lower alum such as lime (200 - 400kg/ha) prior to soil preparation, or fused phosphate (Long Thanh, Van Dien phosphates 100 - 400kg/ha).

7. Care

a) Water Management:

- Lead water into the field 5 days after sowing, water level should be average (cover the rice roots) to help the field to hold moisture well or water level is about 2 - 3 cm. It should observe golden snails (pomacea canaliculata) in field;

- From 7-10 days after sowing, continue to lead water into the field with water level of 5 - 7 cm;

- 28 days after sowing, start to dry off the field for the first time (if the rice rows’ leaves are adjacent to each other);

- From 35-49 days after sowing, lead water into the field, keep the water at level  of 5 cm (preparing to fertilize for the third batch), after fertilization is made, let water naturally recede, until 15 cm below ground surface, then pump water into the field at highest level of 5cm;

- From 80-85 days after sowing, start to dry off the field for rice to be raped and for harvest by reaping machine and the paddy harvesting machine.

Note:Depending on the time of growth of rice to adjust the time of irrigation, not to let rice be flooded throughout the crop.

b) Transplanting: when rice are about 15-20 days old, to transplant additional rice at the places where rice was dead; trim the rice at the places where the density is too thick.

c) Removal: Regularly remove the trees other than rice and weedy rice, the removal stage must be made completely 15 days before the harvest.

8. Pest Management

On the basis of the uniform application of measures, such as careful soil preparation, the flat field, sowing according to the seasonal calendar, use of seeds with high uniformity, sparse seeding, reasonable, balanced fertilizing and good water management to help the rice healthy with thin canopy, thus, it is not favorable conditions for pest development, so it should not need to use pesticide and only use herbicide, except for rice leaf blight, blast, Banded disease as a major.

a) Weeds: Prepare soil carefully and level the field, keep it flood in the early stage to control weeds. Use of drugs of pre or post-germination must be followed the recommended dosage on the label and the field must be warm enough; it should alternate herbicides with different active ingredients to reduce the resistance of weeds.

b) Golden snails (Pomacea canaliculata): Measures of most economic efficiency is to collect Golden snails (Pomacea canaliculata) before sowing seed, lead water to attract them to the sunken places for catching and controlling. If after sowing, paddy fields still have Golden snails (Pomacea canaliculata) with high density, then use chemicals.

c) Brown planthopper: Manage Brown planthopper by the manual instructing the prevention and fighting against Brown planthopper, dwarf yellow disease, twisted leaf dwarf of the Ministry of Agriculture and Rural Development. It should not use Pyrethroids to kill Brown planthopper because it is easy to make resistance and fire pests. It is encourages to use biological products derived from Bacillus thuringiensis and Beauveria fungus, Metarhizium, ...

* Note: Not to use pesticide derived from Acetamiprid to prevent pests from rice’s flowering stage.

d) Small leaf rolling insect (Cnaphalocrosis medinalis Guenee): Applying the method of integrated pest management IPM (main principles: the healthy rice plant, protection of natural enemies, regularly farm visiting, the farmers becoming experts) and not to use drugs in first 40 days after sowing because the Rice at this time is capable of resilience. Use chemicals by 4 rights (right time, right medication, right dosage, right way).

đ) Disease:

- Blast (blast in rice): based on variety characteristics (infected variety) and weather conditions which are convenient for damaging leaf blight’s development (fogs and cold weather at night), it must pump water into the field and use chemicals to treat.

To prevent rice flowers’ neck blast, it should be sprayed chemicals for prevention before and after the rice flowers... because when the rice is got this disease, in addition to reduction of productivity, it shall cause the significant reduction of the quality of rice as milled like increase of percentage of broken rice and rice chalkiness.

- Banded disease.

- Sanitation of field for cleaning grasses and the residues of the previous season.

- Plowing and exposure of soil to help profitable microorganisms’ development to kill germs.

- Water source in the small irrigation canals with water hyacinth, sclerotia should be paid attention when it is led into the fields, when this source of water is used, it should use the net to prevent sclerotia from the fields.

- Yellow leaf: Because the sowing of seeds is made with appropriate seeding density and fertilizer is used reasonably, so it should not need to use chemicals to treat leaf yellow disease. In case yellow leaf disease arising in the early ripening stage is detected to have more than 30% of leaves with disease signal, it can be sprayed chemicals with Benomyl active element.

- Rice leaf blight: The disease spreads by way of seeds. To manage disease, mainly using resistant varieties combined with seed treatment as recommended. Avoid fertilizing in excess of nitrogen in the field detected symptoms of disease. If the disease grows in rainy condition, it should be treated with special medications under instructed dose.

- Flat seeds: In the Summer – Fall season, if the rice flowers in the storm conditions, it may spray chemicals for prevention for 7-10 days before and after flowering with chemicals that prevent flat seeds disease.

*Note:The spraying of plant protection chemicals need to be applied by 4 rights (right chemicals, right time, right dosage, right way).

IV. Binh Thuan Province

1. Seasons

a) Winter – Spring season: starting from 15/11 to 15/12;

b) Summer – Fall season: starting from 15/3 to 30/6;

c) Crops: starting from 15/8 to 30/9.

2. Soil preparation

The field surface must be leveled flatly, made drains, and cleaned up the weeds before the sowing, transplanting is made.

3. Variety preparation

- Use certified seeds;

- The main rice varieties: ML 202, ML 214, ML 48, IR 59606, OM 4900.

4. Seeding density

Depending on variety, season, surface flatness of field surface and drainage capability of the field plot to determine seeding density, appropriate seeding density is from 150kg - 200kg/ha.

5. Soak of seeds and seed treatment

Seeds are soaked with clean water for 48 hours, keep carefully for 24 hours until the seeds germinate. Then proceed to sow freely or with row seeding tool

6. Fertilizers

- Principles of fertilization for rice: to fertilize by the plant needs at time of growth (rise seeding, tillering, rice flowers); fertilize the correct dosage; not to fertilize in excess of nitrogen. Fertilization period for rice can be divided into 3 main batches: Batch 1: from 7-10 days after sowing, Batch 2: from 18-22 days after sowing, Batch 3: from 40-45 days after sowing:

Particularly for land cultivated 3 seasons in many years, it could be added 20% of total amount of nitrogen, and should be added organic fertilizer for soil improvement.

Use the leaf color reference sheets to control the excess of nitrogen in the last 2 batches of fertilization.

Depending on the characteristics of cultivated area, the different soil types, different rice varieties, to publicize the use of fertilizers as follows:

- The amount of fertilizer per ha:

+ Nitrogen (N): 90-100 N

+ Phosphate (P2O5): 30-40 P2O5

+ Potassium (K2O): 30-40 K2O

Particularly for the varieties with growth time of more than 100 days and land cultivated 3 seasons in many years, it could be added 20% of total amount of nitrogen.

- Method to fertilize:

+ Basal fertilizing: Before sowing. Lime shall be fertilized after the first soil preparation. Depending on the acidity of the soil, to increase or decrease the amount of lime applied accordingly. Alum land is applied basal fertilization of phosphate fertilizer from 100-400 kg/ha depending on the acidity of the soil, to lower acidity from the beginning, for the roots to grow better.

+ Top dressing: 03 main batches of top dressing are divided as follows:

Batch 1: When the rice is 2-3 leaves (after sowing about 7-12 days) or after transplanting about 5 days to faster rice seedling’s development, for rice seeding to early tiller, with 30% nitrogen, 100% of phosphate if using single phosphate fertilizer, 50% of phosphate if using DAP and 50% of potassium.

Batch 2: Top dressing for the second time is made when rice is 18-22 days. Use 40% of total amount of nitrogen and 50% of remaining phosphate if using DAP.

Batch 3: Top dressing for the third time is made before the rice flowers about 15-20 days. Use the amount of remaining nitrogen and potassium fertilizer. At this stage, it needs to observe the rice’s top (length of 0.5 - 1 cm) to determine the time of fertilization and leaves’ color to determine the amount of fertilizer.

7. Water management

Depending on the time of growth of rice to adjust the time of irrigation, not to let rice be flooded throughout the crop; keep the water level in the field about 05 - 10cm.

8. Pest Management

- Prevent weeds from the beginning of rice season with chemicals of pre- or post-germination, depending on the status and condition of the field’s water management.

- Golden snails: dig drains, catch Golden snails before sowing; if density of golden snails is high, then use the chemicals in the allowed list for the eradication, it should pay attention to comply with Rule of 4 rights (right chemicals, right time, right dosage, right way).

- Rice leaf folder: rice at the period of within 40 days after sowing (or rice at the period of after 40 days after sowing but the density is under 10 folders/ m2) shall be no need treatment with chemicals.

- Brown planthopper: The most important solution is to select time for the sowing so that it can avoid planthoppers’ migration waves in the period of rice’s 20 days after sowing; therefore it needs to closely monitor the quantity of planthoppers to jump into the lights for the sowing; the most safety to sow rice is the time after the peak batch of planthoppers to jump into the lights; after sowing if planthoppers are also scattered, then use water to shield, if this measure is taken well, it will be no need to use pesticide to spray for rice of less than 1 month old. When rice is more than 1 month old, if the density of planthoppers is more than 3 planthoppers/branch, then use chemicals by the rule of four rights (right chemicals, right time, right dosage, and right way). At period of rice’s 40 days after sowing, take advantage the field’s moisture to promote prevention of planthoppers by using biological or natural chemicals (useful disease sources available on the field) to create a balanced ecosystem and help to control density of planthoppers in a sustainable way.

PROCESS OF LIVESTOCK HUSBANDRY OF CHICKENS, DUCKS SUBJECT TO PILOT INSURANCE
(Issued together with Circular No.47/2011/TT-BNNPTNT dated June 29, 2011 of Ministry of Agriculture and Rural Development)

A. SUBJECTS AND SCOPE OF APPLICATION

This procedure shall specify the order, content and technical requirements in breeding chickens, ducks (laying, meat), applied to the provinces and cities directly under the Central Government participating in pilot agricultural insurance.

B. CONDITIONS OF APPLICATION

I. PROCESS OF RAISING CHICKENS

A. The process of raising chickens

a) Breed selection:

Breeds must be healthy, have clearly-known origin, be quarantined, free from the epidemic areas.

b) Care of chicks:

In the first week, chicks are kept in the circle enclosure. Enclosure is made of compressed weaved bamboo or trellis. Each enclosure contains from 300 – 500 chicks. It must be lined by trimming of 10cm thick in the enclosure. Right in the middle of the enclosure, there must be heating tool by gas. Chicks are heated constantly in the first week with heating temperature reduced gradually from 330C to 300C. Humidity is from 60-70%. Lighting must be conducted all day and night. The feed is the one for chick care, is contained in the square trays made of toile, and dietary is freedom. Water is contained in gallons trough. If the cold season comes, it must use warm water. Supplement vitamins to strengthen the resistance of chickens according to veterinary sector process.

c) Raising chickens for meat:

After 1 week of age, the chicks are let out of the enclosure and raised in the stables. The stable floor is lined with trimming or rice husk of 10cm thick. Enclose the corners of stable for chicken to avoid being dead by compressed weaved bamboo, continue heating chicks until they are 21 days old. If cold winter comes, it needs to heat additionally chickens until they are 28 days old, and then keep stable’s temperature stably at 22 - 250C. Quit gallons trough; fit automatic breast drinking troughs. Remove chick feeding trays, use round trough P50 for meat chickens. Use a mixture feed for meat chickens or mixed feed with corn, bran, rice, broken rice of prestigious animal feed production establishments. Use these types depending on the stages and the manufacturer s instructions.

d) Prevention of epidemics:

Implement full vaccination according to provisions of veterinary sector. Regular inspect and weed out sick chickens. Always check, keep the stable floors dry, if they are wet, change other pad layers. Feeding, drinking troughs must be replaced daily, cleaned and dried before put into use. Implement isolation, not to let people or animals be in or out the breeding area; not to use the same raising instruments between the raising stables. Actively kill rat, birds, insects in the breeding area. Regular make cleaning, disinfection, sterilization of the environment, breeding facilities, farming tools. Implement biosafety, the same in, and the same out in animal husbandry; be empty stable at least 21 days between each rearing litter. If it was epidemic before, empty stables at least 3 months.

2. The process of breeding hens

a) Breed selection:

Before put into breeding for laying, it needs to choose breeds at the stage of broiler chickens and preservation chickens. Select the hens having developed hips, deep chest, shiny hair, bright red crest. Breeds brought must be quarantined and free from the pandemics.

b) Breeding technique:

Preservation hens preparing for laying the first time (5%) are chosen for breeding for laying eggs. The industrial hens are often raised in industrial stables. The stables usually have 3 boxes, each stable contains 3 hens, and can be piled into many stable layers. Under the feeding, drinking troughs is the stand to collect eggs. It must have padding layer under the stable floor, usually sprinkle lime powder to dry falling stools. Feed: is the one exclusively used for hens, and can be used mixed feed for directly feeding or type of concentrated feed mixed with corn, broken rice, rice, paddy .... The quality and quantity of feed depend on the formula for each type, laying stage. In particular, crude nitrogen: 15-17%, ME: 2,700-2,800 kcal/kg, the ration is from 110 gr - 120 gr/hen/day.

For the breeds with a twofold purpose, hybrids can be raised in floor stables or floor stables combined with floor grazing. Density is from 3 -4 hens/m2. Layout the laying litters. Line the stable with padding layer by rice husk, shavings.

Lighting: hens need more light. When hens began to lay, it needs to enhance the lighting period, an additional 15 minutes per day until reaching 14h/day and stabilize until the end of culture. Lighting intensity: 5W/m2.

c) Epidemic disease prevention:

Implement full vaccination according to provisions of veterinary sector; regular make hygiene, antitoxic, disinfection of feeding, drinking troughs, farming facilities, livestock equipment. Daily monitor flocks of hens, weed out the sick hens, if signs of disease are detected, it should immediately notify the veterinary officers and immediately take preventive measures.

II. PROCESS OF RAISING DUCKS

1. The process of breeding ducks for meat

a) Selection of breeds:

Choose the healthy, one-day-old ducks with moderate weight, depending on varieties. Weed out the ducks with wet hair, rare hair, bent legs, crooked beak, anomalies. Breeds should be quarantined, must be known clearly their origins.

b) Raising ducklings:

In the first week, ducklings are kept in the circle enclosure. Enclosure is made of compressed weaved bamboo or trellis. Each enclosure contains from 200 – 300 ducklings. It must be lined by pad in the enclosure. Right in the middle of the enclosure, there must be heating tool by gas. Ducking is heated constantly in two first weeks with heating temperature reduced gradually from 320C to 280C. Humidity is from 60-70%. Lighting must be conducted 24/24. The feed is the one for duckling care, is contained in the square trays made of toile, and dietary is freedom. Water is contained in gallons trough. If the cold season comes, it must use warm water.

c) Raising ducks for meat:

After 1 week of age, the ducklings are let out of the enclosure; continued to heat until they are 14 days old; keep stable’s temperature stably at 22 - 250C; dietary is freedom. For captive ducks for meat, it can be used mixed feed for directly feeding or type of concentrated feed mixed with corn, bran, rice, broken rice…Use these types depending on the stages.  For grazing ducks, depending on the rate of collecting natural food  to distribute additional feed; feed twice: one before grazing and one for late afternoon when ducks are brought to stables, including rude nitrogen: 20 - 21%; ME: 2,800 – 3,000 kcal/kg.

Farming facilities need ventilation projected with natural light to kill bacteria. Its floor surface is hard for easy cleaning. It can be raised completely captive in the stables, and can be combined with grazing (after 1 week of age) for the hybrid ducks, native ducks. Drinking troughs are the gallon one used for the first week and the long troughs used for the stages from 2 - 7 - 8 weeks old to be fitted in middle of stables. Feeding troughs are the toile, steel or concrete one installed or constructed at two sides of the stables.

d) Prevention of epidemic disease:

Implement full vaccination according to provisions of veterinary sector; regular make hygiene, antitoxic, disinfection of feeding, drinking troughs, farming facilities, livestock equipment. Daily monitor flocks of ducks, weed out the sick one, if signs of disease are detected, it should immediately notify the veterinary officers and immediately take preventive measures.

2. The process of breeding laying ducks

a) Selection of breeds:

Breeding ducks are the one to be of the varieties like CV 2000, Khakhicambell, Star 13, Zhejiang, the twofold purpose varieties between grass ducks and exotic ducks with native grass ducks. Before raised for laying eggs, it needs to choose breeds at the stage of preservation. Breeds should be quarantined, must be known clearly their origins.

b) Breeding technique:

Exotic ducks should be raised in complete captivity, but it should combine with the places having water source, density of three ducks/m2. Lighting is conducted all day and night with intensity of 5 W/m2. Domestic ducks and ducks of twofold purpose are raised mainly as grazing, but it is still required to have stables to manage, feed and collect eggs. It needs to layout the laying nests, feeding troughs, drinking troughs in the stables, and the padding layer changed usually to avoid humidity. Eggs laying ducks raised in complete captivity can be eaten mixed feed for directly feeding or type of concentrated feed mixed with corn, bran, rice, broken rice…Use these types depending on the stages. For grazing ducks, depending on the rate of collecting natural food  to distribute additional feed; feed twice: one before grazing and one for late afternoon when ducks are brought to stables, including rude protein: 17 - 18%; ME: 2,700 – 2,800 kcal/kg. Feeding rate is 130 - 150gr/duck/day.

Dry farming without water for ducks to swim is required to double drinking water compared with normal needs and it is needed to change water regularly to ensure that it is always clean. Drinking troughs are arranged in the playground to avoid getting stables wet, not to place too far away from the places ducks eat. When drinking troughs are placed outside the stables in summer, it is required to cover them, avoid ducks drinking hot water.

Daily inspect the situation of ducks flock such as weight, laying rate, feed collection.... Weed out the one to be illness, poor eating; clean up troughs, sweep away the leftovers, foul, mold feeds; add more litter, especially laying nest. Limit the strong impact of light, sound and other unusual effects. If the phenomenon of biting each other of ducks, it should rebalance the ration, stretch breeding density, add more vegetables, cut beak; collect eggs in the morning from 6-7 o’clock.

c) Epidemic disease prevention:

Implement full vaccination according to provisions of veterinary sector; regular make hygiene, antitoxic, disinfection of feeding, drinking troughs, farming facilities, livestock equipment. Daily monitor flocks of ducks, weed out the sick one, if signs of disease are detected, it should immediately notify the veterinary officers and immediately take preventive measures.

+ For the old pond: lime an amount of 100-200 kg/ha;

+ Removal of extraneous matter: Use some types of chemicals killing extraneous matter permitted for circulation in Vietnam and use according to directions on labels;

+ Fertilization creating natural feed culture: 7 days prior to stocking breeding shrimps, use inorganic fertilizers to fertilize the pond. Use additional biological products, or artificial algae to create water color and culture beneficial bacteria in the pond;

After 7 days, if breeding shrimps have not been dropped, it must re-conduct the measure fertilizing to create natural feed for the pond;

+ Drugs, substances of treatment and improvement of the environment used must be the one included in the list of those permitted for circulation in Vietnam and as directed by the manufacturer.

b) Stocking the breeding shrimp:

- Time to raise per season: 3-4 months (from PL 15);

- The number of breeding seasons per year: 1-2 seasons;

- Stocking season: In compliance with farming seasonal calendar of each locality;

- Breeding shrimp must be ensured quality by Vietnam standards and current regulations of the Ministry of Agriculture and Rural Development; it must have quarantine certificates of specialized management agencies. Breeding shrimps must be bought from the facilities which have been issued certificates of achieving quality standard;

- Stocking density: more than 20 shrimps/m2;

- Regulated size of breeds: PL15;

- Stocking method: stock at dawn or dusk, when pond water’s temperature is low in day. Avoid stocking shrimps when it is hot; water temperature is high or when it is raining. It needs to soak breed bag in the breeding pond for about 10-15 minutes before stocking shrimp into the pond.

c) Care:

Feeding shrimps: use industrial pellet feed processed domestically or imported feed for feeding shrimp. Quality of feed must be ensured to have the total nitrogen content from 30 to 40%. Feed and its additives must be on the list of feed which are allowed to circulate in Vietnam.

- Every day, check the pond banks, culverts, ditches, detect and promptly handle leaks, hollows, landslides;

- Regularly clean trash nets, water filter, floor of feeding, remove trash and dirt, algae around the pond, banks, pond corners, manholes, water fan.

- Always ensure content of dissolved oxygen in water more than 4 mg/liter according to the breeding technical requirements by the following measures:

+ Each pond should have an air compressor to blow air from the pond bottom to increase volume of dissolved oxygen and evenly distribute water oxygen;

+ Each pond should put at least two water fans to increase volume of dissolved oxygen and produce flow for the waste collection into the middle of pond bottom;

+ Time and mode of operation of the above machinery depend on the amount of oxygen dissolved in water, density and size of shrimp. In general, the number of hours of operation is increased from a few hours each day in the first month of culture to 14-16 hours per day when approaching harvest time. On the days of bad weather, it can operate the machines continuously all day; in the course of use, regularly check the system of water fans; aeration machine to repair, adjust promptly the damages;

- Once every 10 days, sample breeding shrimp (30 shrimps/sample) to check the growth rate. In the first two months, it is sampled with hooves, from third month onwards, it is sampled with casting-net;

- Regularly check ponds, if trash fishes are detected, it must be handled timely by use of chemicals killing miscellaneous matters.

e) Management of shrimp health:

- Regularly observe shrimp activity, especially at night in order to promptly detect abnormalities in the pond;

- Once every 10 days, sample one time to observe supplementation, the color of shrimp body, the feed in the stomach, intestines, gills, liver, pancreas;

- When finding the shrimps to have abnormal or pathological signs, must clearly identify the reasons for handling.

g) Harvest:

- Use casting-net to catch sampling to check medium volume and the expression of shrimp diseases. If the shrimps have reached an average size of more than 25g/individual, then conduct the harvest;

- The shrimp farms must stop using antibiotics, chemicals before the shrimp harvest as directed by the manufacturer.

- Time of feeding shrimps and amount of feed each time in day: Refer to in the following table:

Table: The time of feeding shrimps and amount of feed each time in day

- The amount of feed is based on age and weight of shrimp in ponds under the manufacturer s instructions;

- Method of feeding: When feeding shrimp, it must spread evenly throughout the pond surface. Each feeding, it needs to check the status of shrimp’s feed use to adjust feed intake accordingly for the next time. Method to check and adjust as follows:

+ Each ha of shrimp breeding pond is placed from 6 to 8 trays (floor of feeding) around the pond. Area of each floor of feeding is about 0.4 to 0.8m2. After spreading feed evenly throughout the pond surface, retain from 2-4% of the amount of feed which has just fed shrimp to spread in the floor of feeding; about 1-3 hours later, re-inspect the floor of feeding to decide on the increase or decrease of the amount of feed for the next time;

+ When finding the shrimp to be molt, reduce 20-30% of amount of feed for the next time;

+ When finding the shrimps to get feed poorly, pond water to be unclear or on the hot sunny days, water temperature is high, reduce the amount of feed for shrimp;

+ In the cool days, it can increase the amount of feed for shrimp.

d) Water Management:

- Treatment of water to supply to the breeding pond: During the pond preparation and before stocking breeding shrimp, it must take water into sedimentation containing ponds for biological treatment. If water is contaminated, it must be handled by chlorine treatment with a concentration of about 30 ppm for 12 hours or fomol with a concentration of 30ppm or chemicals on the list of permitted circulation in Vietnam. Not to get water into the pond in the rainy, storm days.

- Get water into the breeding pond: Regular maintain the water pond depth of 1.5 m or more.

- Supplement water for the breeding pond: On the hot days, water temperature and salinity increase highly, it must timely to add new water treated to stabilize the temperature and salinity for shrimp breeding ponds. Amount of newly added water each time is about 10-15% by volume of pond water.

- Change water for the breeding pond:

+ When the pond water is contaminated or shrimps are ill or shrimps are difficult to mould, it must carry out withdrawal of pond bottom water layer of about 10-15% of volume of pond water to replace with new water treated for the pond;

+ When the pond water salinity exceeds 30%, it must add fresh water to reduce salinity below 30%.

- Check the quality of pond water:

+ Daily monitor the indicators of dissolved oxygen, pH, temperature, depth, clarity and color of pond water;

+ Periodically, monitor the indicators of environmental factors of the pond water such as BOD, NH3-N, H2S, NO2-N to adjust to suit the raised shrimp.

đ) Pond Management: Contents of pond management include the following tasks:

- Every day, check the pond banks, culverts, ditches, detect and promptly handle leaks, hollows, landslides;

- Regularly clean trash nets, water filter, floor of feeding, remove trash and dirt, algae around the pond, banks, pond corners, manholes, water fan.

- Always ensure content of dissolved oxygen in water more than 4 mg/liter according to the breeding technical requirements by the following measures:

+ Each pond should have an air compressor to blow air from the pond bottom to increase volume of dissolved oxygen and evenly distribute water oxygen;

+ Each pond should put at least two water fans to increase volume of dissolved oxygen and produce flow for the waste collection into the middle of pond bottom;

+ Time and mode of operation of the above machinery depend on the amount of oxygen dissolved in water, density and size of shrimp. In general, the number of hours of operation is increased from a few hours each day in the first month of culture to 14-16 hours per day when approaching harvest time. On the days of bad weather, it can operate the machines continuously all day;

In the course of use, regularly checks the system of water fans, aeration machine to repair, adjust promptly the damages;

- Once every 10 days, sample breeding shrimp (30 shrimps/sample) to check the growth rate. In the first two months, it is sampled with hooves, from third month onwards, it is sampled with casting-net;

- Regularly check ponds, if trash fishes are detected, it must be handled timely by use of chemicals killing miscellaneous matters.

e) Management of shrimp health:

- Regularly observe shrimp activity, especially at night in order to promptly detect abnormalities in the pond;

- Once every 10 days, sample one time to observe supplementation, the color of shrimp body, the feed in the stomach, intestines, gills, liver, pancreas;

- When finding the shrimps to have abnormal or pathological signs, must clearly identify the reasons for handling.

g) Harvest:

- Use casting-net to catch sampling to check medium volume and the expression of shrimp diseases. If the shrimps have reached an average size of more than 25g/individual, then conduct the harvest;

- The shrimp farms must stop using antibiotics, chemicals before the shrimp harvest as directed by the manufacturer.

 

APPENDIX VIII

TECHNOLOGY PROCESS OF IMPROVING EXTENSIVE FARMING OF SHRIMP (PENAEUS MONODON) SUBJECT TO PILOT INSURANCE
(Issued together with Circular No.47/2011/TT-BNNPTNT dated June 29, 2011 of Ministry of Agriculture and Rural Development)

1. Subjects and scope of application

This procedure shall specify the order, content and technical requirements for improving extensive farming of shrimp (Penaeus monodon, Fabricus 1798), applied to the farms in the provinces and cities directly under the Central Government participating in pilot agricultural insurance.

2. Conditions of application

- Pond has an area of 7,000 m2or more; water depth of 1.2 m or more; The ponds having area of more than 1 ha will be required to have from 1/3 to 1/2 pond’s area reached a depth of at least 1.2m. Pond banks must be firmly; not be leaked to keep the water and prevent the spread of disease if the environment of the breeding area is not good.

3. The process of improving extensive farming of shrimp (Penaeus monodon)

a) Preparation of ponds:

- Dredge the pond bottom mud layer about 20cm deep to avoid dredging too deep because the salt-water lands have potential acid layer away the ground surface only about 50cm. Repair pond banks, clean grasses, trash and dirt;

- Lime: Depending on the pH of the soil to fertilize appropriate amount of lime;

- Dry the pond bottom.

b) Water treatment:

Get water into pond through net preventing miscellaneous matters, damages. Pond water level is from 1.2 m or more. Use chlorine with an amount of 30g/ water cupid meter or other chemicals according to manufacturer s instructions for water treatment, after 5 days, conduct the creation of watercolor; mix DAP inorganic fertilizer with water to spread evenly around the pond with an amount of 300 - 500g/100 m2of pond for water quickly to have color. Encourage the farms use biological products for water treatment. When water’s color is the yellow color of the green peas cover, then stock breeds. If drugs, substances of treatment and improvement of the environment are used, they must be the one included in the list of those permitted for circulation in Vietnam and as directed by the manufacturer.

c) Removal of trash fishes:

The case by case basis, if there are many fierce fishes in the pond, kill them by the following forms: Use chemicals as directed by the manufacturer or kill them by such means as: fishing, spreading a net ... It should keep the fishes eating natural food, eating selectively, not eating shrimp to clean water and have extra income.

d) Selection of breeds:

Choose the uninfected, healthy breeds which have been supplied by the prestigious producing farms that have been grant certificate of qualification. It should stock PL12-PL15-sized shrimps. Shrimp breeds must be granted certificate of quarantine by the competent authority. Method of selection of breeds is as follows:

- Methods of sense organs: Healthy breeding shrimps shall have bright color, no uninjured, same sizes, agile; slender, long, spreading fan-shaped tail, closed V-shaped beard when swimming. It can assess health of shrimps by using water basin to stock shrimp in, rotate water, healthy shrimp will cling to the basin wall, swim upstream; and weak shrimp will be primarily collected in the middle of the basin, when tap into the basin wall, healthy shrimp will respond quickly by flip jump, in addition, it can check with "shock" salinity.

- Method of causing shock by salinity: Take 100 breeding shrimps and stock into the glass of water (a half of the water taken from the breeds farms and a half to be fresh water) and wait for 45 minutes - 1 hour. If shrimps are died under-5 shrimps, that breed can be chosen for stocking.

đ) Stocking and training of breeds:

- Training of breeds: pure method (salinity, pH, temperature ....): Stock all shrimps and water of the shrimp bag into a plastic barrel of 60 liters, then take water of the shrimp breeding pond to pour into the plastic barrel containing shrimp breeding (5 minutes pour 1 liter), or use water bag to hang on the barrel mouth for water to flow gradually into the barrel. Until the barrel is filled with water, then it can proceed to stock shrimps into the pond.

- Stocking breeds: It should stock shrimp in a wind-swept place, stock at dawn or dusk (not stocking when it is heavy rain). Stocking density is from 8-10 shrimps/ m2.

e) Environmental management in the pond:

Because of extensive farming form, so it is difficult to manage factors such as alkalinity, dissolved oxygen, temperature, NH3 and H2S toxic gas ... so we can only manage factors such as pH, water clarity and color.

Pond water is good conditions for micro-organism and algae to grow, so depending on which algae dominates, it will make the water color be different and also affect shrimps:

- Yellow-brown water: Mainly caused by Tao Khue (Diatomeae), this algae is a good type of feed for shrimp;

- Pale blue water: caused by green algae, this is also a good type of feed for shrimp;

- Dark blue water: caused by deep blue algae, this algae is not good for shrimp’s growth (growth retardation) and causes the phenomenon of blue shrimp (treatment by replacing 30-50% of water in the pond);

- Dark brown water: caused by Tao giap (dinoflagellata). This algae can cause environmental contamination, be very harmful to the shrimps. (Discharge water in, out constantly to clean up the environment combined with the use of racket to pick up the Lap Lap in the pond);

- Yellow water: caused by yellow algae, causing malnutrition to environment, so shrimp shall be slow to grow and survival rate is low. (Handling by replacing 30-50% of water in pond and lime CaCO3 with a dose of 15-20 kg/1,000 m3water);

- Clear water or water with rusty yellow: formed by alkaline soil so pH is very low. Algae is less developed, shrimps are lack of feed, slow to grow and survival rate is low;

To stabilize the water quality in shrimp pond, it needs to pay attention to water intake, do not get water into the pond when water of the channel (river) is too dirty, to discharge surface water in pond and lime CaCO3 of 15 - 20kg/1,000 m2on pond banks at the times of heavy rain. It is better to use lime of CaCO3 with a dose of 15 - 20kg/1,000 m3after the end of harvest to kill miscellaneous matters, disinfect, stimulate algae growth and to avoid the shrimp’ being shocked by the pH change.

g) Management of feed in the pond:

Because shrimps are raised under form of improving extensive farming, so the shrimp density is less than 10 shrimps/m2, not using industrial feed, its major feed source is natural feed (algae and micro-phytoplankton) which is available in shrimp ponds. To complement feed for raised shrimps, leaves can be added into pond such as Mangrove leaves, “Mam” leaves (with the highest nitrogen content), “Da”, “Gia”, weeds, vines .... Because bacteria decompose these leaves into good feed for shrimps, and this is also the source of green manure to improve the color of pond water and enable the beneficial algae growth and development. It can periodically use biological products under the manufacturer s instructions.

h) Epidemic management: This is one of the very difficult tasks in the process of improving extensive farming of shrimps, because shrimps are raised in a wide area, so it could not be based on treatment with drugs and chemicals, but can only control epidemics through the inputs. A few notes for farmers to be able to limit the epidemics during the shrimp farming process:

- Repair pond according to proper technique;

- Select and stock the good breeds which have been quarantined;

- Apply the method of taking and discharging water through the sewer (referred to in section 1) to clean water;

- In the case shrimps got trouble, the water level in the pond must be lowered down to one third for a period from 15-30 days, at the same time use the manual method (pick up the shrimp got disease) in order to avoid spread of disease.

i) Harvest of shrimps: After shrimps are about 4-5 months old, it can harvest them.

*Note:During the shrimp farming, not to use drugs, chemicals, antibiotics which are in the banned list (the Circular No.15/2009/TT-BNNPTNT). If feed, drugs, biologic products, products of treatment and improvement of the environment are used in shrimp farming, they must be the one included in the list of those permitted for circulation in Vietnam.

Body length: body length is more than 9mm, shrimps have the same size, and different ratio is not more than 10%.

- Breeding stocking:

+ Stock shrimps into the pond when the pond water has been created color well for enough natural feed for shrimps. Before shrimps are stocked, it needs to check the environmental factors such as pH, alkalinity, salinity ... between the breeding farms and ponds. If there is a difference, it must be adjusted appropriately to avoid causing shock to the breeding herd;

+ Stock at dawn or dusk, when pond water’s temperature is low in day. Avoid stocking shrimps when it is hot; water temperature is high or when it is raining. It needs to soak breed bag in the breeding pond for about 10-15 minutes before stocking shrimp into the pond:

+ Stocking season: Compliance with seasonal calendar of each locality;

+ Stocking densities: more than 60 shrimps/ m2.

c) Care, Management:

+ Feed and feed supplements must be the one included in the list of those permitted for circulation in Vietnam;

+ Feeding (number of times to feed, amount of feeding, method of feeding) is in compliance with instruction of the manufacturer;

+ Regularly monitor the use of shrimp feed to adjust properly to avoid causing waste and feed excess polluting the water in the pond.

- Management of ponds environment: Regular monitor water color changes, changes of environmental indicators, shrimp health to take measures of timely handling.

* A few notes:

+ The water level in the pond should be maintained at lowest level as 1.4 m;

+ Periodically, supplement probiotics to limit environmental pollution;

+ Raise the water level to achieve maximum level for temperature stability;

+ When getting the water in, it needs to consult environmental monitoring information provided by the agency of local fisheries management.

* Note:During the shrimp farming, not to use drugs, chemicals, antibiotics which are in the banned list (the Circular No.15/2009/TT-BNNPTNT). If feed, drugs, biologic products, products of treatment and improvement of the environment are used in shrimp farming, they must be the one included in the list of those permitted for circulation in Vietnam.

d) Harvest

- The farms raising shrimp (litopenaeus vannamei) must stop using antibiotics, chemicals before harvest of shrimp occurs as directed by the manufacturer.

- When the shrimps reach the size of 70-100 shrimps/kg, it should conduct the harvest. Before proceeding the harvest, it needs to monitor molting cycle, limit state of shrimp’s soft shell at the above period./.
