Sequential breeding method for prawns and blue crabs

Abstract

The invention discloses a sequential breeding method for prawns and blue crabs, and relates to the technical field of mariculture. The sequential breeding method includes the steps of breeding pond selecting, breeding pond disinfecting, young shrimp testing, young shrimp throwing, shrimp feed throwing, young crab throwing, crab feed throwing, water quality managing, catching and the like. According to the sequential breeding method, under the condition that the prawns are bred, the blue crabs are jointly bred, high-yield breeding of the prawns and the blue crabs is guaranteed through breeding pond selecting, young-shrimp throwing time selecting, young-crab throwing time selecting, feed throwing amount selecting and the like, and the new efficient breeding method is provided for retail investors and large-scale breeding.

Although the breeding scale of prawns and blue crabs is huge now, they are basically free-range farming, and each farmer’s farming methods are different, and some farmers have not mastered scientific farming techniques, thus resulting in large investment and low output. question

Both prawns and blue crabs can be cultured in a breeding pond, but now they are more specialized in breeding. Although there may be blue crabs in the shrimp and shrimp ponds, and prawns in the blue crab and crab ponds, most of them are not. Take the initiative to do it, and sometimes even prawns and blue crabs will interact and avoid each other

However, under the premise that the farming scale of prawns and blue crabs is getting bigger and bigger, the profit margin is gradually compressed. It is difficult to obtain high profits by simply farming prawns or blue crabs. Farmers need to change their farming ideas to adapt to changes in the situation
