An efficient method for constructing half-sib families of Chinese prawns

Abstract

The invention discloses a method for efficiently establish half-sib families for penaeus chinensis. The method includes steps of 1), strengthening nutrition cultivation for family penaeus; 2), marking the family penaeus individually for breeding; and 3), regulating the three steps with environmental conditions. The method for efficiently establishing the half-sib families for the penaeus chinensis simple to operate can remarkably improve success rate of establishing the half-sib families, and can meet subsequent requirement for large-scale penaeus chinensis breeding.

Description

Technical field [0001] The invention belongs to the Chinese prawn family breeding technology, and is a method for effectively performing inter-family breeding and improving the success rate of half-sibling family construction by artificially regulating the directional mating of Chinese prawns in the selective breeding process. Background technique [0002] In the 1990s, some countries in the world began to use large-scale family selection techniques for genetic improvement of shrimp, and obtained some valuable varieties. For example, the Hawaii Institute of Oceanography in the United States has bred a fast-growing and tauravirus-resistant strain by constructing a family of Litopenaeus vannamei and using the comprehensive index breeding method; the French Ocean Development Research Institute has bred an anti-infectious strain through family selection. Blue prawn strains with subcutaneous and hematopoietic necrosis virus; Australian Commonwealth Institute of Science and Indust...
