Crayfish
First, create a good lobster growth environment. Lobsters are crustaceans with a pair of particularly well-developed claws and a habit of digging burrows, usually near the water's edge. Lobsters prefer shade and are afraid of light. They crawl out of caves when the light is weak or dark, and sink to the bottom or hide in caves when the light is strong. According to the habits of lobsters, a 50 cm high anti-escape net can be added to the river pond to prevent the lobsters from escaping. At the same time, the river pond simulates the ecological environment of lobsters under natural conditions. 10-15% of aquatic plants and cover are planted shallowly on the edge of the pond to create an environment for lobsters to inhabit and shed their shells, and to reduce killing each other.
The impact of water quality on lobster production cannot be ignored. The quality of the water directly affects the healthy growth and development of lobsters. During the breeding process, the pH value of the pool water is maintained between 7.5-8.5, and the transparency is 30-40 cm. New water must be added frequently, quicklime solution should be splashed regularly, and adjusted Water quality to prevent the occurrence of diseases and unsuccessful shelling.
The second is to feed feed reasonably. Lobsters will kill each other when hungry and underfed, so the amount of feeding must be sufficient. The feed of lobster is animal and plant feed. Plant-based feeds include wheat, aquatic plants, rapeseed cakes, etc., and animal-based feeds include miscellaneous fish, miscellaneous meat, and animal offal. Usually, the feeding time, feeding amount and feeding method are determined based on the diurnal and nocturnal habits of lobsters and the density of shrimp in the pond. Otherwise, the feed cost will be increased and the breeding efficiency will be reduced.
The third is scientific fishing. In the lobster farming process, when the temperature is suitable and the feed is sufficient, the young shrimps can usually grow to commercial size in 60-90 days. Seedlings are released in March, and harvesting begins around June. The big ones are sold and the small ones are kept. By catching the big ones and keeping the small ones, and rotating the catches and releasing them, the catch rate can be increased and sold at a good price, thus achieving the goal of high yield and high efficiency.
