Rapidly proliferated brine shrimp in high-temperature and high-salinity environments and domestication method thereof

Abstract

The invention provides a rapidly proliferated brine shrimp in high-temperature and high-salinity environments and a domestication method thereof. The domestication method achieves gradual enhancementof adaptability of the brine shrimps to the extreme high-temperature and high-salinity environments by feeding the brine shrimps with mixed feeds by stages, and after domestication is completed, by continuously feeding the brine shrimps with the mixed feeds, ensures intake of polyunsaturated fatty acids (EPA) by the brine shrimps, maintains permeability of the cell membranes of the brine shrimps and ensures absorbency of the brine shrimp to nutrients in the extreme high-temperature and high-salinity environments, so that the problem of proliferation of the brine shrimps in brine making pools of salt lakes in summer with an upper temperature of 32-38 DEG C, a degree of salinity of 15-18 Baume degrees or a degree of brine salinity of 160-190 g / L. The domesticated rapidly proliferated brine shrimp in the high-temperature and high-salinity environments can continuously and rapidly proliferate under the premise of continuous mixed feed feeding, so that the material costs for purchasing juvenile shrimps and the time cost for repeated domestication can be reduced, and technical support can be supported for industrialized development.

Description

technical field [0001] The invention belongs to the field of cultivation, and relates to a method for cultivating Artemia, in particular to a method for multiplying and domesticating Artemia in a high-temperature and high-salt environment. Background technique [0002] Artemia (Brine Shrimp) is also called saltwater Artemia, and Chinese folks are also called salt worms or brine shrimp; it belongs to the phylum Arthropoda, Crustacea, Branchopod, Anocaria, Saltwater Artemia, Artemia (Artemia) . Artemia is rich in protein, complete in amino acid composition, relatively high in fat and polyunsaturated fatty acids, and rich in trace elements and growth factors. Artemia, as a high-quality live bait, is widely used in shrimp, crab, sea fish, freshwater fish and ornamental animal larvae breeding, and is the most widely used biological bait. About 40,000-50,000 tons of fresh Artemia are used for aquatic economic animal breeding in my country every year. So far, there is no substitu...
