River crab and goldfish intercropping ecological efficient breeding method

Abstract

The invention provides a river crab and goldfish intercropping ecological efficient breeding method. The breeding method comprises the following steps: a culture area is selected as a culture pond; aquatic plants are planted in the culture pond in the first year of culture; in the early spring period, goldfish fry and crab fry are put into the culture pond; and after the crabs and the goldfishes are mature, the crabs and the goldfishes are sold on the market. According to the breeding method, crabs and four-tail goldfishes are bred together, organic matter at the bottom of the culture pond is subjected to aerobic decomposition through microbial thalli on the basis of bait aquatic plants and algae of the crabs, the number of insects in the water body is reduced by breeding the goldfishes, a biological chain cycle is formed in the water body, by referring to a natural biological ecological chain, the stability of the biological chain is artificially maintained, and the purpose of ecological breeding is achieved.

Description

technical field [0001] The invention mainly relates to the technical field of river crab ecological breeding, in particular to an ecologically efficient breeding method for river crab and goldfish nesting. Background technique [0002] Crabs, also known as river crabs, are freshwater crustaceans that grow up in freshwater. The crab meat is delicious and nutritious. Crabs have been generally recognized as a delicacy by Chinese and overseas people. At present, because the source of crabs is still mainly fishing, less artificial cultivation work has been carried out. In artificial breeding crabs, they are very dependent on chemical agents. The multiple use of the agent has a great impact on the environment, and it is easy to affect the growth status and growth rate of the crabs, etc., resulting in the inability to further improve the quality, specifications, taste, etc. of the crabs. [0003] In order to breed high-quality crabs, it is necessary to implement a healthy breeding...

AI Technical Summary

Problems solved by technology

[0004] At present, there are still many deficiencies in the technology of artificially raising crabs, and people's experience in artificially raising crabs is not yet perfect.

Breeding crabs require different baits at different stages, and require different growth environments. Many technicians ignore the scientific setting of the ecological environment for crab farming when breeding crabs, use industrial compound feed, and use drugs blindly, causing damage to the ecological environment of crabs. Crab survival rate is low, quality declines
