Knowledge about lobster cultivation, lobster breeding methods and conditions

Can you keep lobsters in Inner Mongolia.

The first is to create a good environment for lobster growth. Lobsters are insect shellfish, with a pair of particularly developed chelae, and have the habit of burrowing, generally digging burrows near the water's edge. Lobsters are shady and afraid of light, crawling out of burrows when the light is weak or dark, and sinking to the bottom or hiding in burrows when the light is strong.

According to the habits of lobsters, a 50 cm high escape net can be added to the river pond to prevent lobsters from escaping. At the same time, the river pond simulates the ecological environment of lobsters under natural conditions, and 10-15% of aquatic weeds and hidden objects are planted shallow on the edge of the pond to create an environment for lobsters to inhabit and shell, and reduce mutual killing. The impact of water quality on lobster production cannot be ignored.

The quality of water quality directly affects the healthy growth and development of lobsters, during the breeding process, the pH value of the pool water is kept between, the transparency is 30-40 cm, new water should be added frequently, and quicklime solution should be splashed regularly, and the water quality should be adjusted to prevent diseases and shelling. The second is to feed reasonably. Lobsters can kill each other when they are hungry and underfed, so the amount of feed must be sufficient.

The feed of lobsters is animal and plant feed. The plant-based feed is wheat, aquatic weeds, rapeseed cake, etc., and the animal-based feed is trash fish, miscellaneous meat and offal. Usually according to the habit of lobsters in the day and night and the shrimp in the pond.

Lobster breeding methods and conditions:

1. Breeding environment.

1) The pond water is required to be clean and pollution-free, the water quality pH value is between, and the transparency is about 30cm.

2) Apply 100-200kg of organic fertilizer per mu before seedling, and cultivate plankton as natural bait for lobsters.

3) The pond is required to have good water intake and drainage measures, and set up mesh at the water inlet and drainage outlet, that is, to avoid trash fish from entering the breeding site, affecting the growth of lobster, and also to prevent lobsters from escaping with drainage.

4) Add water exchange facilities, aeration equipment and other breeding facilities around the area.

2. Disinfection of clear ponds.

You can splash quicklime all over the pond to disinfect the pond, and clean up natural enemies such as snakes and rats, and it is also required that there are no trash fish in the pond.

3. The area of aquatic plants.

The area of aquatic weeds should not be too large, generally not more than 1 2 of the pond area, if there are too many aquatic weeds, it will affect the absorption of nutrients by crayfish.

4. Daily management.

1) Inspect at least once a day to observe the water quality, lobster activities and eating, change the water regularly, and increase oxygen in time when the dissolved oxygen is insufficient.

2) Remove the diseased shrimp in time to avoid the shrimp from getting sick.

Lobster farming technology:

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.

Breeding lobster, need to be bred in a pond with sufficient water source and good water quality, before breeding, it is best to plant some aquatic plants in the pond, which is conducive to the growth and habitat of lobster, you can also add an appropriate amount of fertilizer and bait in the pond, and then you can breed lobster into it, and you can feed it once a day in the morning and afternoon during the breeding period.

1. Pond requirements

Lobsters have a strong ability to adapt to the environment, they can generally be bred in ponds, ponds need sufficient water sources and good water quality, water depth is about 1 meter, and the pond needs to be built around the meter high inner wall smooth escape wall, and then build some mud stalks in the pond, so that lobsters can grow.

2. Plant aquatic plants

When breeding lobsters, you also need to plant some aquatic plants in the pond, because aquatic plants can be used as food for lobsters to eat, which is conducive to the growth of lobsters, and aquatic weeds can also replenish nutrients for the water body and purify water quality, aquatic weeds can also provide a hidden and perched place for lobsters.

3. Apply fertilizer

The growth of lobsters needs sufficient nutrients, so when preparing to breed lobsters, you can apply some organic fertilizer and creatures as bait in the pond, pay attention to not apply excessive fertilizer when applying fertilizer, generally according to the fat and thinness of the water body, each time should not exceed 80 kg.

4. Maintenance management

Preparations are done, you can put the lobster fry into the pond, lobster is an omnivorous species, during the breeding can be mixed animal and plant feed lobster, feeding time is generally at ten o'clock in the morning and four o'clock in the afternoon, in the afternoon to feed more.

1. Pond conditions: ensure that the water quality is transparent and clear, and the water depth is about 1 meter. 2. Apply basal fertilizer:

4. Prevention and control of diseases: often disinfect the ponds, and divide the ponds for water cultivation after lobsters are infected with diseases.

1. Pond conditions

When breeding lobsters, it is necessary to ensure sufficient water sources, so that the water depth is about meters, and the transparency of the water body should be controlled at 20 cm, and aquatic plants should be planted in the pond to allow lobsters to grow in a hidden environment.

2. Apply basal fertilizer:

In the process of raising lobsters, it is necessary to add organic fertilizer to the pond to ensure the fertility of the water body, so that the microorganisms and plankton in the water can grow rapidly, but not more than 80 kg per mu, so as not to grow lobsters in the pool water with excess nutrients.

3. Feeding time

Lobsters are omnivorous creatures and need to be fed animal feed, and lobsters like to forage at night, so it is best to feed after 6 p.m. and once after 10 a.m.

4. Prevention and control of diseases

In order to prevent lobsters from getting sick, the pond needs to be disinfected during the feeding process, and chemicals should be added to the feed to be fed.
