Abstract

The invention relates to a label control method in an indoor intermediate breeding stage in a tidal shellfish family breeding process, in particular to a breeding family juvenile mollusk intermediate temporary rearing method. The problems that in the prior art, the survival rate of juvenile mollusks is low, the cultivation cost is high, and the breeding operation difficulty is high are solved. A plurality of groups of culturing barrels are arranged in a culturing pond, growth conditions of the various culturing barrels are the same, and the breeding cost can be reduced; and moreover, the method is simple, the survival rate is high, and the method is suitable for breeding a plurality of families, and meets requirements of development of the large-scale shellfish family breeding industry.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to the cultivation of tidal flat shellfish, in particular to a method for intermediate temporary cultivation of juvenile shellfish of selected breeding families. Background technique [0002] Breeding of aquatic animal families has become one of the important means in selective breeding and an important way to improve the germplasm of aquatic animals. During the family breeding of tidal flat shellfish, since the planktonic period of larvae is generally 6 to 12 days, metamorphosis occurs when the shell grows to 200-250 μm, and the short time is convenient for family selective breeding. After the metamorphosis of the larvae, because the juvenile shells are relatively small, they cannot be marked on their juvenile shells, nor can they be mixed. On the other hand, studies on the interim cultivation of tidal flat shellfish spat show that if the tidal flat shellfish spat with a shell length of 3...
