Bay scallop breeding method

Abstract

The invention discloses a bay scallop breeding method. The bay scallop breeding method includes steps of 1) selecting a pond with sand substrate and disinfecting with water by bleaching powder or quick lime; 2) feeding water lower than 0.5 meter and adding fertilizer in ten days before juvenile scallops are placed into the pond, and feeding water to the highest level in two to three days before the juvenile scallops are placed into the pond; 3) setting a floating stem on a raft and fixing two ends of the floating stem by timber piles; 4) arranging a juvenile scallop curtain and utilizing a mesh bag with 60 meshes until the juvenile scallops bred to more than 400micrometers; 5) adding a mesh sheet into the mesh bag for supporting a juvenile scallop collecting bag; 6) gradually increasing daily water refreshment quantity in the second day after the juvenile scallops are placed into the pond; 7) keeping increasing water refreshment quantity within 3 days before dividing the scallops; 8) uniformly distributing the juvenile scallops on the mesh bag in two days after the juvenile scallops are subpacked, and moving the juvenile scallops to the sea and waiting for sales. By the above technical scheme, the bay scallop breeding method adopts scientific breeding technology, the bred scallops are fast in growth and fresh in meat, and the bay scallop breeding method is higher in output that other breeding methods.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating bay scallops. Background technique [0002] Gulf scallop was introduced from the United States by the Institute of Oceanography, Chinese Academy of Sciences in 1982. After many efforts, it has developed into one of the main cultured species in the north. With its advantages of short breeding period and quick results, it has brought significant benefits to the vast number of coastal breeding units and fishermen. economic benefits. [0003] However, in recent years, due to the instability of seed production and the low growth rate in the middle, it often brings great economic losses to nursery farmers and breeding production units. [0004] Contents of the invention [0005] The technical problem mainly solved by the present invention is to provide a culture method of bay scallops. [0006] In order to solve the above technical problems, a technical solution ...
