Problems solved by technology

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

Embodiment

[0020] The invention provides a method for successively cultivating prawns and blue crabs, comprising the following steps:

[0021] (1) Selection of aquaculture ponds: The aquaculture ponds should be located near the confluence of rivers, streams and seas or the inner bay where sea and fresh water are buffered and exchanged. The aquaculture ponds should be conducive to drainage and water diversion. Subsidence, the depth of the breeding pond is 1.4m, the water level of the breeding pond is 1.2m, and the area of ​​the breeding pond is 8 mu;

[0022] (2) Disinfection of breeding ponds: Disinfect the breeding ponds before throwing seedlings, put lumps of quicklime into the breeding ponds with half of the drainage, and put them in at an amount of 200kg per mu;

[0023] (3) Shrimp seedling test: After the breeding pond is sterilized for 7 days, take the prawn seedlings to be cultured to test the water. When the survival rate of the shrimp seedlings in the test seedlings reaches more...

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.

Description

technical field [0001] The invention relates to the technical field of mariculture, in particular to a method for successively cultivating prawns and blue crabs. Background technique [0002] Prawns and blue crabs are important and valuable seafood, and their farming is also one of the important industries along the coast, with large-scale farming and good economic benefits. 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 an...
