Problems solved by technology

[0003] With the continuous expansion of the scale of freshwater shrimp farming and the rapid development of production, there are many problems in the freshwater shrimp farming industry. The efficiency cannot be improved, and at the same time, it is affected by external factors, such as salinization factors, temperature factors and disease factors, which all cause the problem of low survival rate of shrimp seedlings. For this reason, we propose to use hybrid backcrossing of freshwater shrimp and Macrobrachium hainanensis to effectively solve the problem. Shrimp seedlings generally have problems such as low survival rate

Abstract

The invention discloses a breeding method of hybrid backcross freshwater shrimps, and relates to the technical field of freshwater shrimp breeding. The method comprises the following steps: S1, selecting a shrimp pond; S2, desilting and disinfecting the bottom of the pond; S3, culturing water in the shrimp pond; S4, selecting shrimp seed varieties; S5, carrying out hybrid backcross of the shrimp seeds; S6, feeding the shrimp seeds with feed; S7, conducting water quality management; S8, conducting shrimp seed management; and S9, fishing adult shrimps. According to the breeding method of the hybrid backcross freshwater shrimps, Taihu Lake freshwater shrimps and Hainan male macrobrachium are subjected to hybrid backcross, the obtained hybrid backcross freshwater shrimps are high in disease resistance and high in yield, and the bred hybrid backcross freshwater shrimps have the advantages that the disease resistance, high temperature resistance and low temperature resistance of the shrimps are obviously improved and the finished shrimps are great in physique, large in size and full in meat and has bright color and luster and high yield; and according to the method, the problems of low survival rate and the like generally existing in shrimp seed management in the later stage are effectively solved, so that the breeding rate and the growth speed of the shrimp seeds are increased, and the traits of the freshwater shrimps after stable hybrid backcross are improved.

Description

Technical field [0001] The present invention relates to the field of green shrimp cultivation, and is specifically a cultivation method of hybrid back green shrimp. Background technique [0002] The green shrimp is affiliated to the articular animal door, the crust mark, the top, swimming and shrimp, the long arm shrimp, Hainan mastun shrimp, Baihe Shrimp or large pliers, which is mainly distributed in the South In the coastal area, the lower reaches of the Lectoral in Zhejiang Province are rich in the shrimp, and their individual is large, but also compared with Roche Maimi, find the maximum male individuals up to 200 grams, but the meat is more delicious, and the cultured technology of green shrimps is more mature. Especially in the pond of green shrimp. [0003] With the continuous expansion of the serial size of the green shrimp, there are many problems in the rapid development of the production, and there are many problems in the serial shrimp, and the existing green shrimps...
