Abstract

The invention provides an ecological breeding system for grass shrimps. The system comprises a breeding area, a plant area, a water qualification area A and a water qualification area B, wherein watertreated in the water qualification purification area B flows back to the breeding area through a pipeline; the breeding area is inoculated with vallisneria spiralis, hydrilla varticillata and ceratophyllum demersum, the ratio of planting areas of vallisneria spiralis, hydrilla varticillata and ceratophyllum demersum is 1:(5-8):(5-7), and interplanting is performed; acorus calamus, cress and laverare planted in the planting area, the ratio of planting areas of acorus calamus, cress and laver is 1:(5-7):(2-3), and interplanting is performed; activated carbon is placed in the water quality purification area A, effluent from the area A is drained to the area B, a nitrobacteria solution and bacillus subtilis are added to the area B, the content of nitrobacteria in water reaches (1*10<5>)-(2*10<5> cfu/mL, and the content of bacillus subtilis is (1*10<6>)-(2*10<6> cfu/mL; and a filtering net is arranged at a water outlet of the area B. With the adoption of the method, circulation of breeding water can be realized, resources are saved, intake of the grass shrimps is effectively promoted, growth of the grass shrimps is accelerated, and the weight of the grass shrimps can reach 28-36 g after the grass shrimps are bred for 90 days.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a grass shrimp ecological breeding system. Background technique [0002] Grass shrimp belongs to the prawn family, and its scientific name is Penaeus monodon, also known as black shell shrimp. Grass shrimp has the characteristics of fast growth, miscellaneous food habits, wide-salinity, short breeding cycle, delicious meat, and rich nutrition. It is the largest species in the genus Penaeus and is favored by consumers. At present, the farming mode of grass shrimp is mainly pond culture. During the breeding process, a large amount of water needs to be changed, the waste of water resources is serious, and there are environmental pollution problems in sewage discharge. Therefore, the current farming mode has restricted the development of the grass shrimp farming industry. It is necessary to seek a sustainable recirculating aquaculture system. In the current culture mode, after ...
