Continuous culturing method for two-year-five-crop prawns

Abstract

The invention belongs to the field of shrimp culture and discloses a continuous culturing method for two-year-five-crop prawns. The continuous culturing method for two-year-five-crop prawns concretely comprises steps in that during the first crop, South America prawns and fishes are mixedly cultured around the Tomb-Sweeping day; during the second crop, penaeus japonicus are stocked around the Autumn Begins day; during the third crop, South Africa prawns are stocked around the First Frost Day and cultured in a winter shed around the Light Snow day; during the fourth crop, the South Africa prawns and fishes are mixedly cultured around the Tomb-Sweeping day of the next year; and during the fifth crop, penaeus japonicus are stocked around the Autumn Begins day of the next day. The culturing mode has the great advantage of stable production. The prawn and fish mixed-culturing mode has excellent stability; the penaeus japonicus has high economic value; winter shed prawns are welcomed by farmers due to stability and high profits; three excellent culturing modes are combined, rational seedling releasing density is set out and scientific set meals matches and detailed daily management are arranged, so farmer earnings can be greatly improved; and a system solution scheme is provided for the prawn culturing industry.

Description

technical field [0001] The invention belongs to the field of shrimp culture, in particular to a sustainable shrimp culture method for two-year and five-year production. Background technique [0002] Shrimp farming is the pillar industry of aquaculture in my country and even in the world. In the 1980s, the development of shrimp aquaculture led to the development of my country's aquaculture industry, promoted the economic development of coastal areas, and promoted the simultaneous development of related industrial chains such as seedling breeding, bait production, and refrigeration processing in coastal areas. In the 1990s, especially since 1992, due to the spread of shrimp virus disease all over the country and the lack of appropriate countermeasures by aquaculture workers, the economic benefits of shrimp aquaculture plummeted. Therefore, after aquaculture workers studied shrimp virus diseases, explored new alternative species and new economic growth points in the shrimp far...

Problems solved by technology

With the continuous deterioration of the breeding environment, the degradation of seedlings, the decline in the quality of feed products and many other problems, the previous model of intensive shrimp farming is no longer suitable for today's farming environment, so it is urgent to find a sustainable breeding road
