Embodiment Construction

[0039] The sustainable cultivation method for prawns of the present invention is carried out according to the conditions of the following table:

[0040] Table 1 Time for seedling placement

[0041]

[0042]

[0043] Note: Before placing the seedlings each time, test the seedlings: take a part of the shrimp seedlings and seal them with a mesh bag and sink them to the bottom of the pond, and calculate the survival rate after 24 hours to check whether the shrimp seedlings are adapted to the pond bottom.

[0044] The third method of placing the vannamei shrimp is to make a thick label first, and set up a winter shed. After a month of breeding, that is, before and after the light snow solar term, the thick labeled vannamei shrimp can be placed in the built winter shed pond.

[0046]

[0047] The first and fourth fish are omnivorous fish and omnivorous partial carnivorous fish. The omnivorous fish is preferably tilapia, and the stocking d...

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...
