A new method of comprehensive matching for light culture of Penaeus vannamei

Abstract

The invention discloses a comprehensive matched new method for penaeus vannamei bred in fresh water. The method comprises the step that in the breeding pond of the penaeus vannamei, gurnards, catfishes and margarya melanioides are subjected to matching stocking, wherein the stocking size of the gurnards is 100 g-150 g per fish, the stocking rate is 10-15 per mu, the stocking size of the catfishes is 100 g-200 g per fish, the stocking rate is 20-30 per mu, and the stocking rate of the margarya melanioides is 50-100 kg per mu. Accordingly, the death rate of penaeus orientalis is effectively decreased, growth of the fishes is promoted while the penaeus orientalis bait utilization rate is increased, and the mouthfeel of fish meat is optimized.

Description

technical field

[0001] The invention relates to the field of culture technology of Penaeus vannamei, in particular to a new comprehensive matching method for light culture of Penaeus vannamei. Background technique

[0002] The meat of Penaeus vannamei is delicious, the processed meat rate can be as high as 67%, the suitable temperature range is 18-32 ℃, the suitable salt range is also wide, and it can grow under the condition of salinity 1-40‰. It is an excellent Dilution of cultured species. At present, the culture of Penaeus vannamei tends to be intensive, high-density, and high-yield, and requires a short breeding cycle. Under the conditions of large-scale intensive farming, the survival rate of Penaeus northern and southern shrimps in freshwater aquaculture is not high. The reason is the water quality of shrimp farming. The root cause of affecting the water quality of shrimp farming is the bait problem. Too much residual bait will lead to eutrophication of the water bo...
