Takifugu obscurus three-stage type culture process

Abstract

The invention relates to a takifugu obscurus three-stage type culture process. According to the process, indoor and outdoor processes are combined, the wild takifugu obscurus natural growth and development environment is artificially simulated, the process comprises three stages, and the three stages concretely comprise the steps of fish fry greenhouse reinforced culture, fingerling open air wild pool fattening and young fish greenhouse nature simulation overwintering. The takifugu obscurus cultured through the process provided by the invention has the advantages that the growth speed is high, the nutrition is balanced, the immunity is high, the meat content is high, the survival rate is maintained at a value higher than 95 percent, in addition, the fresh flavor of the wild takifugu obscurus is remained, the unique quality and flavor and the rich nutrition are realized, and the economic benefits and ecological benefits are obviously improved.

Biology and breeding technology of puffer obscura. Scientific fish farming, 1998(2): 18) basically adopt carp The breeding mode of the family fish and the four major domestic fishes has led to problems such as slow growth, small size, serious diseases, and low survival rate of cultured pufferfish.

Coupled with the abuse of fish medicines, the cost of breeding has increased, the quality of commercial fish has declined, and the benefits have been low
