Abstract

The invention belongs to the field of aquaculture, and particularly relates to a method for culturing one-year patinopecten yesoensis. The method effectively avoids vigorous attachment periods of mussels, oysters and heterogeneous algae by one-time seedling separation and three-time cage inversion so as to improve the survival rate of seedlings; the quality and the specification of the seedlings are promoted by seedling selection; and the density is reasonably dispersed and the living space is expanded so as to facilitate the growth of the seedlings. The method is suitable for large-scale offshore culture, and has great significance for the development of the shell industry.

Description

technical field

[0001] The invention belongs to the field of aquaculture, and in particular relates to a method for cultivating first-year-old scallops. Background technique

[0002] Ezo scallops are native to Japan and the Far East of Russia. They are cold-water shellfish and are distributed in coastal sea areas with high salinity, hard bottom without fresh water injection, less silt and water depth not exceeding 40m. It is one of the excellent varieties of scallops in the world that are more suitable for artificial breeding. my country introduced it from Japan in the early 1980s and mainly cultivated it in the Liaodong Peninsula in northern my country, Shandong Changdao and other sea areas. The growth rate is relatively slow. From juvenile shellfish From the beginning to the shell height of 11-12cm, the shortest time is 1 year and 7 months. According to records, the maximum shell height can reach 27.94cm, and its life span is about 25 years.

[0003] In recent years, due ...

Examples

Embodiment Construction

[0018] The present invention will be described in detail below with the case of cultivating one-year-old scallops in the sea area of ​​Changhai County, Dalian City, Liaoning Province.

[0019] A culture method for scallops, adopting floating raft type net cage culture, the culture method includes at least two parallel floats, floats are arranged on the floats, the distance between the parallel floats is 10m, the culture cage hangs Hanging on the float, the scallops are in the culture cage, each culture cage has 20 layers, the height of each layer is 15cm, the diameter of the culture cage is 34cm, and the seawater flow rate in the culture area is greater than 1.5km / h. The specific steps are as follows: figure 1 Shown:

[0020] (1) In July every year, when the average seawater temperature reaches 18°C ​​to 19°C, screen scallop seedlings with a shell height of more than 0.5cm and put them into breeding cages with a mesh of 0.5cm, and put 150 scallops in each layer of breeding cag...
