Method of male selection of green shrimp

Abstract

The method for male selection of freshwater shrimps, involving aquaculture technology, is characterized in that: using laser induction technology in the best effective time period of freshwater shrimps to induce all young shrimps to be male; During the period of time, the female shrimp seedlings were killed using hormone technology, and all the male shrimp seedlings were obtained. The present invention solves the territorial consciousness of male shrimp in the breeding pond, cannot mate, and does not need to fight, thus becoming a mechanical shrimp for meat production; and because the male shrimp is large, it solves the problem that the freshwater shrimp is small and the shrimp is not willing to be deep-processed. The price of shrimps must be higher than that of small shrimps; under normal circumstances, male shrimps are twice as large as female shrimps, so the output can also be more than doubled.

Description

technical field [0001] The invention relates to aquaculture technology, in particular to a method for male selection of freshwater shrimp. Background technique [0002] Freshwater shrimp, also known as Macrobrachium japonica, belongs to the phylum Arthropoda, Crustacea, Decapoda, Longarmidae, Macrobrachium genus, and its geographical distribution is very narrow, limited to my country and Japan. Because of its delicious meat, high nutritional and economic value, fast growth, short cultivation cycle, low feed requirements, easy self-propagation of seedlings, and all-weather cultivation, etc., since the end of the 1980s when it entered the heyday of aquaculture development, aquaculture has become popular. The scale is rapidly expanding, and the breeding technology is becoming more and more perfect. It has become the leading freshwater shrimp species in my country and one of the main freshwater famous, premium and new species. The breeding areas are all over my country's Jiangsu,...

Problems solved by technology

[0005] Beneficial effects of the present invention: the present invention solves the territorial awareness of the male shrimp in the culture pond, cannot mate, and does not need to fight, thus becoming a mechanical shrimp for meat production; The question of willingness to further process, the price of large shrimps must be higher than that of small shrimps; under normal circumstances, male shrimps are twice as large as female shrimps, so the output can also be more than doubled
