Ecological breeding method for mixed breeding of gold saddle rabbitfish and giant freshwater prawns

Abstract

The invention relates to an ecological breeding method for mixed breeding of gold saddle rabbitfish and giant freshwater prawns. The ecological breeding method comprises the steps that 1, pond cleaning is performed before water inflowing, pond drying in the sun is performed for 14-16 days, and then water inflowing begins, wherein the salinity of a water body is 3-8; 2, the gold saddle rabbitfish and the giant freshwater prawns are bred in a breeding pond in a mixed mode, wherein the density of the gold saddle rabbitfish is 2500-2600 per mu, and the density of the giant freshwater prawns is 50000-5200p per mu; a seawater floating mixed feed and a giant freshwater prawn feed are fed respectively every day in month before the breeding process; only the seawater floating mixed feed is fed after one month of breeding. By adopting the breeding method, the gold saddle rabbitfish survival rate can be up to 85%, the yield of the gold saddle rabbitfish per mu is up to 192 kg, the yield of the giant freshwater prawn per mu is up to 200 kg, bred giant freshwater prawns are large and few get ill, a breeding effect is remarkable, and the ecological breeding method has a good application prospect.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an ecological culture method for polyculture of S. rosenbergii and Macrobrachium rosenbergii. Background technique [0002] Dianbasketfish is a rare marine omnivorous fish with delicious meat, high protein content, and rich polyunsaturated fatty acids, which is deeply loved by consumers. Point basket fish has strong adaptability and strong tolerance to salinity and temperature, and can be cultured in most areas south of the Yangtze River in my country. After a certain degree of salinity domestication, the basketfish can also be cultured in brackish water. Basket fish likes to eat large algae such as prolifera. It has a mixed diet and a short food chain, which can reduce the investment in aquaculture, which is conducive to the improvement of the breeding environment. Sustained development has far-reaching significance. my country has carried out aquaculture of dangling fi...

Problems solved by technology

Our country has carried out the breeding work of basket fish, but so far, the cultivation of basket fish is limited to seawater cage culture in some areas in the south and brackish water culture in a few areas, and it is mainly used as net cage cleaning fish. Single model, limited breeding area
