Ecological breeding method of efficient polyculture of pseudorasbora parva, crab larva and loach

Abstract

The invention discloses an ecological breeding method of efficient polyculture of pseudorasbora parva, crab larva and loach. The method comprises the steps of: pond conditions, disinfection, breeding water preparation, grass planting, fry breeding, water level adjustment, water quality adjustment and control, feeding management, disease control, daily management and the like. The breeding method provided by the invention focus on the breeding of crab larvae; the pseudorasbora parva is mainly used as cleaners for residual feeds, so that the pollution to water quality can be greatly reduced, the water quality can be improved, the growth of crab larvae and loaches is promoted, and meanwhile, blue-green algae outbreak in the crab larva pond can be biologically controlled by the polyculture of the pseudorasbora parva; the loaches play a role in loosening the soil, and eliminates hazardous substances in the soil in time, so as to avoid the water quality becoming bad due to the high temperature in summer, in addition, loaches do not need additional feeding and management, are beneficial supplement to the breeding of the crab larvae, and thus the pond benefit is greatly increased.

Description

Technical field

[0001] The invention relates to an ecological breeding method of high-efficiency polyculture of wheat ear fish, juvenile crabs and loach, and belongs to the technical field of aquaculture. Background technique

[0002] At present, in freshwater aquaculture, it is generally believed that the single-species aquaculture model is no longer suitable for the needs of production development. Although intensive aquaculture has high yield and is easy to operate, it is greatly affected by the market and has high risks. Therefore, the development of multi-species polyculture mode is the current direction of freshwater aquaculture. By using the habits of different aquatic animals, under the conditions of non-interference and even mutual benefit, the polyculture of different types of aquatic products is what scientific and technological workers have to face. . In order to explore ways to increase the efficiency of juvenile crabs, we conducted research on the ecological breedi...
