A kind of facility and method for parent-breeding mussel breeding and grouping for constructing large-scale family of Triangle sail clam

Abstract

The invention relates to a mussel breeding and grouping facility and method for constructing a large-scale family line of the triangular clam. The facility includes two water supply pools and matching pools equal in number to the builder's coefficient. The water supply pool is connected to each matching pool through pipelines, and can inject water into the matching pool. Each matching group pool is an independent pool body and is provided with an overflow port. The matching group pool is provided with a clam hanging bracket, and the parent mussels are placed in the net clips of the clam hanging bracket. A method for parenting mussel breeding and grouping for constructing a large-scale family of S. triangularis, characterized in that it comprises the following steps: (1) selecting a water supply pool; (2) building a grouping pool; (3) laying pipelines; (4) parenting Identification of male and female mussels; (5) Hanging mussels; (6) Daily management and inspection. The whole set of parent-breeding mussel breeding and grouping facilities for building a large-scale family of S. sinensis is precisely designed to meet the strict requirements of family breeding of aquatic animals. Compared with traditional facilities, it has the advantages of low cost, small construction difficulty, strong controllability and high accuracy. In the process of family building, it is easier to check the fertilization status of parent mussels and daily management, which is more efficient and greatly saves manpower and material resources.

Description

technical field [0001] The invention relates to the field of genetics and breeding of aquatic animals, in particular to a mussel breeding and matching facility and method for constructing a large-scale family line of S. sinensis. Background technique [0002] Triangle sail mussel is the most important freshwater pearl-growing pearl mussel in my country, which has important economic value. my country is the world's largest producer of pearls. The annual output of freshwater pearls exceeds 1,000 tons, accounting for more than 95% of the world's pearl production. However, its actual market output value is far from it. Related to the scarcity of good breeds. The key to the revitalization of my country's pearl industry lies in the selection and breeding of pearl-breeding mussels that produce large-scale, high-quality pearls, and large-scale selection and breeding of S. sinensis is particularly important. Family selection has become one of the important means of selective breedin...
