1. Seed stocking

The quality of seedlings should be selected neatly, the physique is robust, the vitality is strong, the appendages are complete, the specifications of the shrimp seedlings should be consistent, the method is to put into the plastic pot, with salt water for disinfection, can play a role in killing parasites and pathogenic bacteria, and so on the body surface and gill cavity of the shrimp species absorb enough water and then stocking, can improve the survival rate. In general, polyculture with silver carp can be selected to improve water quality.

2. Feed feeding

Lobster growth rate is fast, excessive hunger or satiety, is not good for growth, farmers need to control the number of food intake is of great significance to growth, according to the lobster's feeding situation, to avoid too much feed waste, affecting water quality, greens, aquatic weeds, cake meal, scraps are lobster feed, if there are conditions for farmers friends can also feed pellet feed, higher efficiency.

3. Promote lobster molting

Lobsters need to shed a hard shell in order to achieve the purpose of growth, if the lobster does not molt into an iron but-shell shrimp, because the body of the new shrimp after molting is soft, it takes a period of time for the shell to become hard, so during this time, it is necessary to maintain good water quality, in addition, the lobster molt needs to consume a lot of calcium, phosphorus, iron, so pay attention to the reasonable combination of these nutrients in the feed.

4. Water quality control

Lobster high-yield breeding ponds, good water quality regulation can make lobster farming easier, through regular water injection, and mixed with micro-preparations to reduce the pond nitrite and hydrogen sulfide and other harmful substances.

5. Improve the quality of lobster

In the process of lobster breeding, it is strictly forbidden to use illegal drugs, strengthen feeding management, improve lobster meat yield, and effectively improve lobster production and quality.

Disease prevention. Frequent inspections, frequent patrols of ponds, pay attention to lobsters' foraging, activities, growth and molting, etc., so as to take necessary technical measures in time. Remove moss from the pond in a timely manner; Always check the filter screen at the inlet and drain outlets to prevent lobster escaping or wild trash fish and other harmful organisms from entering due to broken filter screens. Always pay attention to whether there are predators in the pool, such as water rats, water snakes, water birds, etc., and if so, they should be removed in time.

Before the shrimp seedlings go to the pond, the body surface should be disinfected to prevent pathogens from being brought into the pond, the shrimp pond should be disinfected regularly with quicklime, new water should be added frequently, the pool water should be kept clean and hygienic, and a variety of vitamins should be added to the shrimp feed to enhance the immunity of the shrimp.

Timely fishing: generally raised for about 2 months, when the lobster weighs more than 50 grams, it can be caught on the market, and the lobster is fished using shrimp pots, ground cages, purse seine nets and other methods, catching large and leaving small.

1. Pond conditions. The water surface of the pond should not be too large, the suitable water surface is 1 2 acres, the water depth is 1 meter, and it has a perfect drainage system and aeration system; The bottom of the pond has a slight slope, no leakage, and the anti-escape facilities are repaired. Before stocking, the pond must be cleared (dry method) to remove debris and weeds, so as not to leave enemies and pathogens in the pond, and disinfect with 150 200 kg of quicklime per mu of water surface.

Lobsters like shade and fear of light, good at climbing and crawling, require aquatic plants on the water body, accounting for about 1 3 of the water surface, can be planted aquatic plants, such as wheel black leaf algae, grass and so on, at the same time at the bottom of the pond should be set up with bricks, stones and bamboo tubes and other hidden objects for its habitat and burrowing.

2. Stocking of shrimp seedlings. Lime water disinfection can be put after 7 10 days of normal water quality, the water temperature requirements are relatively high, the appropriate growth water temperature is 20 30, less than 15 when rarely eaten. The water body should maintain high dissolved oxygen, and the dissolved oxygen should be more than 50 mg.

The transparency of the water body should be 30-40 cm. pH. Shrimp fry are stocked with centimeters at a stocking density of 4,000 to 7,000 acres.

When the seedlings are released, the plastic bag containing the shrimp seedlings is placed in the pond for 30 minutes and then opened, so that the shrimp seedlings gradually adapt to the water temperature in the pond, which is conducive to improving the survival rate of shrimp seedlings. After about 1 month of stocking, 60 100 acres of 50 250 grams of silver carp can be stocked in a timely manner. Freshwater lobsters are benthic crustaceans, and proper polyculture of pelagic filter-feeding fish can not only improve the growth environment of lobsters, but also serve as indicator fish for hypoxia in ponds.

But do not mix carnivorous and eating fish, so as not to affect the growth of lobsters.

3. Feeding with bait. Shrimp seedlings put in the pond for 30 minutes after the start of feeding, the early stage to feed cooked soybean pulp, and then add a small amount of small trash fish and snail meat, etc., the feeding amount of shrimp weight 6 8%, divided into morning and evening two feeding. According to the feeding habits, the total amount of the day in the evening is about 2 3, and the combination of fixed points and pond sprinkling is adopted.

In the middle stage, the water temperature is high, the feeding is vigorous, and the feeding amount is 10%. In the later stage, shrimp bait can also be fed with 25% of compound feed such as miscellaneous fish, soybean meal, wheat bran, green vegetables, etc., and the daily feeding amount changes with the water temperature, which is flexible to master.

Fourth, daily management. Strengthen water quality management to ensure sufficient dissolved oxygen and fresh water quality. In the high temperature season, prevent shrimp from floating and increase the aerator. When the water quality is too fertilized, use quicklime to sanitize plankton, and splash the whole pool. Pay attention to patrolling the pond to remove predators, frogs, snakes, etc.

The vitality of lobster is very strong, and it can make full use of ponds, rice fields and some barren beaches, small pit ponds and other water bodies for breeding, and the area is suitable for 2001-3335m2. Because the shrimp has the habit of digging holes, the depth of the general cave is 50-80cm, and the depth of some caves is more than 1m, in order to avoid digging holes and escaping, the width of the ridge around the aquaculture water body should be above, and 0 5m high and smooth inner wall is set up around the ridge to prevent escape from the wall or the anti-escape board, and build a good injection and drainage system. At the same time, several mud ridges should be built in the middle of the pond, the two ends of the mud ridge should not be connected with the pond ridge, the length of the ridge is about 4 5 of the pond length, the width of the ridge is more than lm, and the ridge is 5-10cm higher than the water surface, so as to create a place for lobsters to burrow.

The depth of the pool is appropriate, preferably in the middle, with shallows on all sides. At the bottom of the pond, tree roots, bamboo tubes, etc. are placed, and aquatic plants are transplanted on the water surface.

Refers to the technical guidance contact of the fragrant lobster.

1. Seedling cultivation.

The cultivation pond covers an area of 20-40 square meters, and the cement pool with a water depth of one meter is the mainstay, and the pond with better water quality near the water source can also be selected to build drainage and anti-escape facilities. The pond is strictly disinfected before seedling, the basal fertilizer is applied to cultivate plankton to provide open bait, and the transplanted aquatic weed area accounts for 30% of the water surface. 10-150,000 juvenile shrimp per mu are put into the body, and natural bait is mainly used in the early stage, soybean milk and surimi are appropriately fed, and artificial feed is mainly used with the increase of individuals.

2. Pond aquaculture.

10,000 juvenile shrimp are put into each mu, and quicklime is regularly sprinkled to increase the calcium content in the water body, and the amount of night feed is increased, mainly with compound feed.

3. Seed stocking.

There are two methods of crayfish stocking: one is in early September after the rice harvest will be directly put into the rice field, let it reproduce by itself, according to the actual situation of rice farming, generally per mu stocking individuals in 40 grams of more than 20 kg of crayfish, male to female ratio 3:1.

Second, after the rice seedlings are planted in May, 1,500 2,000 or 30 kilograms of juvenile shrimp with a size of 2-4 cm are stocked. When stocking crayfish, we should pay attention to the quality of juvenile shrimp, and the stocking specifications of the same field should be as neat as possible, and we should release enough at one time when stocking. Stocking in the morning on a sunny day or on a rainy day, when stocking juvenile shrimp, wash with a 3% 4% salt water bath for 10 minutes to disinfect.

Lobster breeding technology training includes: seedling density, pond disinfection, shrimp seedling selection, aquatic weed planting, feeding principles, and disease control.

1. Seedling density

Lobster farming no matter which breeding mode, the stocking density must not be too high. Even the intensive culture density in Tangkou should be controlled at 80 to 100 catties per mu, and the density of polyculture mode should be reduced to 50 to 60 catties per mu.

Excessive seed stocking density will bring great pressure to the pond environment and management. It is easy to cause the size of lobster to be small, and shrimp is easy to die due to lack of bait, poor breeding environment, lack of oxygen and other factors.

2. Disinfection of clear ponds

Pond cleaning and disinfection can effectively kill predators in the pond, such as catfish, black fish, snakes, rats, etc., wild miscellaneous fish that compete for food, such as carp, crucian carp, etc., as well as pathogenic bacteria. The commonly used methods are quicklime disinfection, and quicklime has two types: dry disinfection and water disinfection.

Dry disinfection method: 50 to 100kg of quicklime per mu, splash the whole pond, and then pour new water after 3 to 5 days of drying the pond. Water disinfection method: each mu of water surface is calculated with a water depth of 1 meter, and 125 to 150kg of quicklime is dissolved in water, and the whole pool is evenly sprinkled.

3. Selection of shrimp seedlings

Choose shrimp seedlings with neat stocking specifications, strong physique, complete appendages, clean body surface, no injury and disease, and strong mobility, and local high-quality shrimp seedlings are the best.

4. Aquatic weed planting

Aquatic plants are natural bait for lobsters, providing lobsters with a place to perch, molt, shade and avoid enemies, and can also improve the dissolved oxygen of the water body, cool down, regulate and purify water quality, and improve the substrate.

At present, the common varieties of aquatic plants are Elophylla, Melanophyllum rotiflora, Fishfish algae, Vulgaris, Millet grass, Peanut and so on.

5. The principle of feeding

Feed feeding adheres to the principle of "five determinations", and adjusts according to the season, weather, water quality and shrimp activities, and sets up a food table to observe the lobster feeding.

Lobsters have a more mixed diet, and feed on rotifers, cladopods, copepods or aquatic animal larvae in the pond in the early stage of seedling, and cooperate with artificial feeding of minced small trash fish and minced meat.

In the middle and later stages, animal feeds such as small trash fish, artificial compound feed, and plant feed are fed.

6. Prevention and control of diseases

Regularly sterilize and disinfect the water body, and splash it with 10 to 15kg of quicklime slurry every 667 square meters every 10 to 20 days. Diagnose sick shrimp in time, use drugs that meet the national fishery medicine standards**, and do not use drugs blindly.

1. Site: When breeding crayfish, it is necessary to select the old rice field for reconstruction, and build a protective net around the rice field. 2. Delivery:

It is best to stock 40 kg of shrimp fingerlings per acre when the weather is fine. 3. Feeding: When feeding crayfish, it is necessary to provide them with feed with higher protein content.

4. Inspection: Inspect the shrimp pond once a night.

1. Site construction

Breeding crayfish first need to build a good site, the shrimp pond of general crayfish breeding is the use of old rice fields to rebuild, to improve the surrounding embankment and clean up the silt and debris at the bottom of the pond, etc., add fine nets on all sides to prevent crayfish from escaping holes, and enclose a low fence, and install fine nets at the entrance and exit to protect the shrimp ponds.

2. Shrimp seed stocking

Before starting the release of shrimp seeds, a certain amount of fertilizer should be poured into the shrimp pond, and some algae and other plants can be planted after the pond water becomes yellow-green and clear, and after the zooplankton in the pond gradually reproduces and grows, choose to put it in the sunny and cool daytime, and put about 40 kg of shrimp seeds in one acre.

3. Feed feeding

Feed feeding is also very important, crayfish in juvenile size is too small, can only feed on plankton and algae detritus young leaves, and so on after its size gradually grows up, you can prey on benthic aquatic animals independently, feeding it bait with high-protein food-based, animal internal organs can also, but pay attention to the timing and fixed point quantification.

4. Regular inspections

Be sure to regularly inspect the shrimp pond of crayfish, especially when it rains, the water level is **, the lobster is likely to escape, and it is necessary to strengthen the fence and iron net in time to prevent losses, and regularly adjust the water quality according to the situation of the shrimp group to replace fresh water, and timely salvage the food residues and other debris in the pond.
