Abstract

The invention relates to the technical field of aquaculture, and in particular relates to a breeding and culture method for all-male macrobrachium rosenbergii. According to the breeding and culture method provided by the invention, different feed is thrown according to the growth needs of the macrobrachium rosenbergii in different reproduction stages, so that maturation of parent pseudo-female macrobrachium rosenbergii is promoted, and the reproduction cycle is effectively shortened; the survival rate of young all-male macrobrachium rosenbergii is improved, and large-number of young all-male macrobrachium rosenbergii is obtained; and besides, the content of selenium in macrobrachium rosenbergii meat is improved, and the nutrient quality of the macrobrachium rosenbergii is promoted.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a breeding method for all male Macrobrachium rosenbergii. Background technique [0002] Macrobrachium rosenbergii (Macrobrachium rosenbergii), also known as freshwater long-arm prawn and Malaysian prawn, is native to the tropical and subtropical waters of the Indian Ocean-Pacific Ocean. It is one of the largest freshwater prawns in the world. It has fast growth, large individual, It has the advantages of wide appetite, easy domestication, strong adaptability, and short production cycle. The traditional domestic method of cultivating Macrobrachium rosenbergii is to mix male and female shrimp seedlings together. Generally, after 2 to 3 months after the seedlings are thrown, the female shrimps begin to mature and hold eggs. At this time, they generally no longer grow meat. Nutrients are distributed to the eggs. Although the male Macrobrachium rosenbergii does not lay eggs, the...
