Culture cage and culture method for giant freshwater prawns

Abstract

The invention discloses a culture cage for giant freshwater prawns. The culture cage comprises a plurality of metal frames, layering nets, separation meshes and peripheral nets. The metal frames are parallel to each other. The layering nets are connected in parallel between every two adjacent metal frames, and the peripheral nets are connected to side faces between the metal frames. The separationmeshes are connected to the metal frames. The metal frames, the layering nets, the separation meshes and the peripheral nets form a culture space with upper and lower layers. Feed platforms are arranged on the layering nets in the culture space, and the feed platforms of the adjacent layering nets are mutually staggered. The layering nets, the separation meshes and the peripheral nets are netting. The culture cage provides a good place for the giant freshwater prawns, production, transport and storage are facilitated, and the survival rate and yield per unit area of the giant freshwater prawns are increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a giant macrobrachium rosenbergii culture facility, in particular to a giant giant rosenbergii culture cage and a culture method. Background technique [0002] Macrobrachium rosenbergii, also known as Malaysian prawn, is a large freshwater prawn native to Southeast Asia. It has the advantages of fast growth, wide appetite, good meat quality and nutritional content, and short breeding cycle. Macrobrachium rosenbergii has developed rapidly since the artificial breeding. Since my country introduced Macrobrachium rosenbergii in 1976, it has been cultivated in Guangdong, Guangxi, Hunan, Hubei, Jiangsu, Shanghai, Zhejiang and other provinces, and has achieved obvious economic benefits. [0003] Macrobrachium rosenbergii has a strong sense of territoriality, is aggressive, and has the habit of cannibalism, so attention must be paid during the breeding process, otherwise...

AI Technical Summary

Problems solved by technology

Prior to this, when cultivating Macrobrachium rosenbergii, aquatic plants and other plants were planted at the bottom of the pond or boxes and other utensils were placed to provide shelter for the shrimp, so as to reduce the cannibalism of the shrimp and improve the survival rate of the culture, but the effect was not obvious, and the survival rate of the culture Usually below 50%
