A kind of grass shrimp ecological breeding system

Abstract

The invention provides a grass shrimp ecological breeding system, which includes a breeding area, a plant area, a water purification area A and a water purification area B, and the water body treated in the water purification area B is returned to the breeding area through a pipeline; Hydraphylla and hornwort, the planting area ratio of the three is 1:(5~8):(5~7), interplanting; the plant area is planted with calamus, cress and seaweed, and the planting area ratio of the three is 1:(5 ~7): (2~3), interplanting; put activated carbon in the A area of ​​the water purification area, discharge the water from A area into the B area, and add the nitrifying bacteria liquid and Bacillus subtilis in the B area to increase the content of the nitrifying bacteria in the water. up to 1×10 5 ~2×10 5 cfu / mL, the content of Bacillus subtilis is 1×10 6 ~2×10 6 cfu / mL; there is a filter screen at the outlet of area B. By adopting the method of the invention, not only can the recycling of breeding water be realized, resources can be saved, but also the feeding of grass shrimp can be effectively promoted, the growth of grass shrimp can be accelerated, and the body weight of the grass shrimp can reach 28-36 g after 90 days of breeding.

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 ...

Problems solved by technology

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. Need to find a sustainable recirculating aquaculture system

In the current culture mode, after 90 to 100 days of grass shrimp cultivation, the specification is about 20 to 30 per jin, which has not yet reached the maximum benefit. Therefore, it is the main objective of the present invention to further improve the economic benefits of grass shrimp under the circulating aquaculture mode. Purpose
