How to raise lobster

Crayfish is a favorite seafood of many people. In recent years, the market demand for crayfish is growing, and the farmers of crayfish are also increasing year by year. So, how do you raise lobster?

I. Pond conditions

It is best to build a rectangle in a place with plenty of water, open ground and slightly inclined terrain. It is required that the water quality is fresh and pollution-free, the dissolved oxygen in the water is above 4mg/l, and the ph value is 7.0-8.0. In addition to the strong dikes, shrimp ponds can also be surrounded by some simple materials, such as plastic film or plastic net, to prevent lobsters from escaping or the invasion of enemy organisms such as frogs, snakes and rats.

Second, the method of releasing seedlings

1. Seedling release time: generally from April to early June, seedlings can be released when the spring water temperature rises to more than 16 ℃.

2. Selection and purchase of shrimp seedlings: choose seedlings with bright, clean and beautiful body surface, complete limbs and healthy physique.

3. Stocking density: it depends on the specification of shrimp fry, the requirement of cultivation, the condition of shrimp pond and the level of feeding and management. Generally speaking, for lobster seedlings with a body length of more than 1.5~2cm, the amount of lobster seedlings is 5000 to 6000 per 15 ha, and the survival rate is usually more than 70% and 80%.

4. seedling release method and matters needing attention: the water level should be more than 0.8m and 1.0m during seedling release. Due to the great change of air temperature in the seedling release season, the deeper water level is beneficial to keep the water temperature relatively stable. A full number of seedlings should be released in each shrimp pond. It should be scattered in the shallow water around the shrimp pond.

Third, throw in and feed

1. Types of feed

Plant feed: there are soybeans, bean cake, wheat, corn, potato and so on.

Animal feed: fish meal, fresh miscellaneous fish, snail, mussel meat, earthworms and livestock and poultry viscera and so on.

Compound feed: at present, there is no special formula feed for freshwater lobster on the market, which can be replaced by shrimp and hairy crab, or can be prepared by ourselves.

2. Feeding amount: the daily feeding amount of dry food is generally 8%-10% of shrimp weight, 5% of shrimp weight, and 3%-4% of prawn weight. If fresh food is added, it can be appropriately higher than this figure. Lobster feeding should be flexibly controlled and adjusted timely and reasonably according to the weather, water temperature, water quality and other conditions.

3. Feeding method: generally twice a day, in the morning and evening, preferably before sunrise and after sunset, and mainly in the evening.

Breeding crayfish is a project with high economic benefits, and the market prospect is good at present. Interested friends can give it a try.
