How to raise lobsters, how to raise lobsters

The lobster feeding method is as follows:1. Breeding facilities. Breeding lobsters should build ponds with flat bottoms, good water storage and sufficient water sources, with an area of 4-10 acres, and the water depth should be kept in the range of 1 meter to meters, and during the breeding period, plastic film should be used to build protective nets along the edge of the pond to avoid lobsters escaping.

2. Preparation for stocking. One month before stocking lobsters, the water in the pond should be drained, the excess silt should be removed, and then the pond should be disinfected with bleaching powder, and then the rotten farmhouse fertilizer should be applied to it to cultivate plankton, and algae and aquatic plants should be planted at the bottom of the pond to provide a place for the lobsters to hide, rest and molt.

3. Feeding management. Lobster eating is more miscellaneous, in the process of breeding, you can be fed twice a day between July and October every year, mainly fish, snail meat, shrimp meat, watermelon, so that it can consume enough nutrients, and the rest of the season should be fed once a day, and it is best to feed at night, so that the amount of lobster food increases.

1- Environment: Say not too much, just go over the back, if the water depth can be placed stones for it to climb, in the water dissolved oxygen is insufficient and when sleeping at night, it can put half of the gills out of the water to breathe, while paying attention to escape, this guy can use pliers to open the circuit and clamp small objects such as wires to escape.

2-Food: Cline's belongs to the wide range of food, in the wild plant protein and animal protein will be ingested, artificial want to raise for a long time is the same, can not just feed the same food, it is recommended to feed the best shrimp and small fish, the calcium can help the shrimp inside the new shell forming and improve the survival rate of molting, plant protein as far as possible to feed clean vegetables, so as not pesticides to the crayfish nerve center to cause devastating damage.

3- Molting: If you don't eat a few days before molting, don't touch it at that time, and rest and rest; A few days after molting, it is the most fragile, except that the teeth are soft, the higher the temperature, the faster the hardening, at that time it is best not to scratch it, it is easy to cause the shell to deform, after the shell hardens, it is necessary to increase the amount of feeding, the molting is equal to Nirvana, which consumes a lot of energy.

Lobsters are raised from pond disinfection, planting aquatic plants, applying fertilizers, seedling feeding, feeding management, etc.

1. Pond disinfection.

If you want to breed lobsters, then you need to use quicklime to disinfect the pond, the silt in the pond needs to be removed before breeding, and at the same time to eliminate the aquatic animals that are harmful to the lobster, the water quality of the pond needs to be clean and clean, and the lobster should be prevented from escaping before breeding.

2. Plant aquatic plants.

When lobster is breeding, it is necessary to plant some aquatic plants in the pond, which can provide a place for lobsters to inhabit and reproduce, and can effectively increase the oxygen capacity in the pond, pay attention to the planting area in one-third of the pond, otherwise it will adversely affect the growth of lobster.

3. Apply fertilizer.

Lobster can grow more vigorously in the pond with sufficient fertility, before stocking, you can apply an appropriate amount of decomposed fertilizer in the pond Xunxun, through this method, you can quickly cultivate a large number of plankton for lobster to eat, pay attention to the fertilizer should not be too much, so as not to pollute the water body.

4. Seedling feeding.

Put the purchased lobster fry into the pond, feed the crushed fish and meat for it, after the crayfish grows up, you can feed snails, mussels and other foods, the amount of feeding is good to eat enough, in the maintenance process, it is necessary to replace the new water regularly, and to prevent and control the lobster disease.

5. Feeding management.

Lobster eating is more miscellaneous, in the process of breeding, you can be fed twice a day between July and October every year, mainly fish, snail meat, shrimp meat, watermelon, so that it can consume enough nutrients, and the rest of the season should be fed once a day, and it is best to feed at night, so that the amount of lobster food increases.

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 culture.

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.

Third, there are two methods of seed stocking, lobster stocking.

1, 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.

2. After the rice seedlings are planted in May, 1500 2000 juvenile shrimp with a size of 2-4 cm or 30 kg mu are put in. 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.

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.

2. Shrimp fry stocking. 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.

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.

4. Freshwater lobster does not have strict requirements for pond conditions, so it is advisable to choose a place with ventilation and sunshine, soil quality and water retention, and no pollution of water sources to build a pond. The size of the pond is generally 3333 6667 (5 10 acres), and the water depth reaches above.

1. First of all, the treatment of the pond: 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, lobsters like shade and fear of light, good at climbing and escaping, requiring aquatic plants on the water body, accounting for about 1 3 water surface.

2. Shrimp fry stocking. Lime water disinfection can be put after 7 10 days of normal water quality, followed by temperature requirements of 20 30, high dissolved oxygen in the pond, water transparency requirements of 30 40 cm and so on.

3. Before stocking, use quicklime 100 150kg 667 to clean the pond for disinfection, disinfect the water after 3 days, and use 300 500kg 667 to ferment and rot organic fertilizer fertilizer water after 10 days, cultivate rich plankton, and provide sufficient bait for shrimp seedlings.

4. The selection of shrimp temple: the stocking shrimp seedlings generally choose 3 5 cm in length, strong physique, disease-free shrimp seedlings, the stocking density can be controlled at 2000 3000, and the 667 shrimp seedlings with small specifications can appropriately increase the stocking density.

1. Methods of raising domestic lobsters:

1) Buy a fish tank or aquarium, preferably glass, so that you can clearly see the lobster's every move. Get a lid to prevent the lobster from jumping out of the tank. Spread a layer of sand and put some small pebbles to simulate the natural environment more realistically, so that the lobster can adapt to life in the fish tank.

Don't bask in the sun, lobsters are yin.

2) Crayfish are omnivorous, and can be eaten with both plant and animal feed. Plant-based feed. Plant-based feeds include plant straw, aquatic weeds, roots and leaves of aquatic plants, algae, silk algae, organic detritus, etc.

Animal feeds include aquatic insects and screws, mussels, fish, etc.

3) It is best to raise several lobsters together, so that the survival rate of lobsters is relatively high.

4) When the lobster is shelled, the hand stove tomb should be kept separately to prevent the lobster from killing each other.

2. Edible lobster species:

1) Sea water lobster.

The lobster that is most meaningful for human consumption is the large lobster in the genus Lobster, such as the South China Sea lobster (Palinurus versicolor). These lobsters can reach a body length of 30 to 45 centimeters (not counting antennae) and can weigh up to 5 kilograms.

The tail of the live lobster must be slightly rolled up, if the tail is straight, the meat will not taste good when cooked. Generally, the meat of lobster is drier than that of langoustin. The lobster will turn red when cooked.

2) Freshwater lobster.

First of all, a common misconception to explain is that freshwater crayfish are not lobsters. The scientific name of crayfish is crayfish, but it looks more like a lobster.
