Problems solved by technology

[0005] Penaeus vannamei has not been successfully propagated in fresh water in my country so far. The supply of shrimp seedlings is provided by seawater breeding farms with high salinity along the coast. Since shrimp seedlings enter freshwater directly from seawater with high salinity, the osmotic pressure of the breeding water environment varies with the salinity of the water body in a wide range. Mutation occurs due to reduction, which will lead to the death of shrimp body osmotic pressure that cannot adapt to the osmotic pressure mutation of the water environment

Embodiment 1

[0032] Example 1: Using the freshwater osmotic pressure regulator of Penaeus vannamei of the present invention to carry out a culture experiment of Penaeus vannamei. The specific experiment process is as follows: (1) The breeding experiment was carried out in the production, education and research base of Changsha University, and the indoor temperature-controlled glass aquarium was 80cm x 40cm x 40cm. In the breeding system of the laboratory of Changsha University, vannamei shrimp larvae are provided from domestic coastal seawater breeding farms with high salinity. The salinity of the shrimp larvae transportation is 12 degrees.

[0033] (2) The freshwater osmotic pressure regulator of Penaeus vannamei is formulated according to the following chemical substances by weight: sodium hydroxide 1, vitamin C 0.02, vitamin E 0.015, calcium chloride 0.7, pyridoxine 0.015, potassium chloride 0.35, sodium silicate 0.002, well salt 16, creatine phosphate 0.015, boric acid 0.1, glucose 0.01, ...

Abstract

The invention discloses a method for cultivating Penaeus vannamei by using a water body osmotic pressure regulator. The water body osmotic pressure regulator is formulated according to the following chemical substances in parts by weight: sodium hydroxide 1-2, vitamin C 0.01-0.02, vitamin E0. 01‑0.02, calcium chloride 0.5‑1, pyridoxine 0.01‑0.02, potassium chloride 0.1‑0.5, sodium silicate 0.001‑0.003, well salt 15‑20, creatine phosphate 0.01‑0.015, boric acid 0.1‑0.3, glucose 0.01‑0.02, potassium bromide 0.02‑0.04, sodium bicarbonate 0.02‑0.05, magnesium sulfate 8‑10, soybean oligosaccharides 0.1‑0.15, sea salt 20‑25, calcium dihydrogen phosphate 5‑8. By adjusting the freshwater salinity and osmotic pressure of Penaeus vannamei, the growth environment of Penaeus vannamei is adapted from the high-salinity seawater growth environment to the low-salinity freshwater growth environment.

Description

[0001] Technical field: [0002] The invention relates to a method for culturing Penaeus vannamei using a water body osmotic pressure regulator, and belongs to the technical field of aquaculture. [0003] Background technique: [0004] Penaeus vannamei has a wide range of adaptability to salinity, strong disease resistance, fast growth, high meat yield, delicious meat, high protein and low fat, and is suitable for artificial high-density farming. It is the three recognized in the world today. One of the fine varieties of farmed shrimp. Introduced by my country in 1988, it is mainly cultivated in coastal wide-salt waters. However, for a long time, coastal aquaculture has deteriorated water quality, viruses and bacteria ravaged, and natural disasters frequently occur. This has caused coastal aquaculture to reduce production, and domestic consumption of Penaeus vannamei However, it continues to rise. Therefore, in recent years, the domestic white shrimp consumer market has been in short...
