Problems solved by technology

[0003] In recent years, the offspring of Macrobrachium rosenbergii have not grown large during the seedling breeding process. The young shrimp stop growing when they grow to 5-6cm, but their claws grow very long instead. Such shrimp can grow normally and will not die. But it led to a decline in production, waste of feed, and serious losses to farmers
The occurrence of this phenomenon is mainly due to the fact that farmers do not pay attention to the cultivation of shrimp species in the process of raising seedlings, do not select breeding shrimps, and the seedling technology is not standardized, etc.
[0004] In short, the breeding method of Macrobrachium rosenbergii is unscientific, which will lead to low seedling emergence rate and high mortality of shrimp seedlings in the process of raising seedlings, which will cause farmers to reduce production and lose money

Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with specific embodiments.

[0042] A kind of breeding method of Macrobrachium rosenbergii shrimp fry, adopts the following steps:

[0043] Broodstock selection: In October of each year, when the water temperature drops to about 20°C, select qualified seedlings from the fine seed farms to breed broodstock in ponds. Quality requirements: Broodstock shrimp are required to be clean in appearance, strong in body, complete in appendages, and free of lesions in the whole body. The specifications of broodstock are: 40-60 tails / kg for female shrimps; 30-50 tails / kg for male shrimps, and the second step is orange-yellow; the male-to-female ratio of broodstock shrimps is 3-4:1.

[0044] Overwintering cultivation of brood shrimp: Before the brood shrimp enters the pond, the winter pond is first disinfected, and then the brood shrimp is stocked, and the stocking density of the brood shrimp is controlled at 30-5...

The invention provides a macrobranchium rosenbergii breeding method with the advantages of high larvae output rate, high survival rate, high raising nutrition, uniform larvae individual size, clean body surface, no damage or deformity, and increased economic benefit. The method provided by the invention has the advantages of simple operation, low cost, significant effect, and significant economic and social benefits.

Description

technical field [0001] The invention mainly relates to a method for genetic breeding of shrimps, in particular to a method for breeding macrobrachium rosenbergii seedlings, and belongs to the technical field of aquaculture. Background technique [0002] Macrobranchium rosenbergii (Macrobranchium rosenbergii), also known as Malaysian prawns, freshwater long-arm prawns, money prawns, and big river prawns, is the largest freshwater prawn in the world. Lives year-round in fresh or brackish waters in these areas and breeds in tidal-affected estuaries. Macrobrachium rosenbergii is the largest individual among Macrobrachium prawns. Because of its large size, wide feeding habits, few diseases, easy survival, fast growth and good nutrition, it has important economic value. [0003] In recent years, the offspring of Macrobrachium rosenbergii have not grown large during the seedling breeding process. The young shrimp stop growing when they grow to 5-6cm, but their claws grow very long...
