Example Embodiment

[0012] In April 2007, sand filtered seawater was injected into 4 4m×4m×1.8m nursery ponds with a water depth of 1.5m; each pond was disinfected with 12g of strong chlorinated essence for 12h, and then neutralized with sodium thiosulfate; disinfected Sea water aeration for 12h. From the Zhanjiang Wushi Huagui Chlamys farreri scallop breeding population, 120 mature individuals with sex glands were selected as parents. The number of males and females were 80 and 40, and the shells were 1.5 years old. The parent releases gametes after being stimulated by running water, shade drying and warming sea water (temperature increased by 3-4°C). Filter the male and female gametes with a 300-mesh sieve, put them into a 30L plastic bucket, and add 20L of seawater, then add a small amount of mixed sperm to the bucket containing the female gametes, and stir them thoroughly for artificial insemination. 1h after insemination, wash the eggs for the first time. 2h after insemination, the fertiliz...

Abstract

The invention discloses a Chlamys nobilis offspring seed cultivation method. Offspring seeds are pretreated by water and are performed with parent Chlamys nobilis selection, induction for oviposition and artificial insemination to cultivate Chlamys nobilis offspring seed larva. The invention adjusts water quality by processing water for the offspring seed before inputting larva, thus effectively improving larva survival rate and distortion ratio, and lowering production cost.

Description

technical field [0001] The invention relates to a method for cultivating scallop seedlings. Background technique [0002] Chlamys nobilis is naturally distributed in Honshu, Shikoku and Kyushu of Japan, Indonesia and the South China Sea. Chlamys farreri is rich in nutrition and delicious in meat quality. It is one of the main marine economic shellfish in southern my country. In the process of cultivating scallop scallops, static water culture and running water exchange methods are basically used to cultivate seedlings. The specific operation of the static water culture method is to change the water volume of 1 / 3 of the original water volume every day; the water change method is to simulate the sea area environment, and it is a low-speed circulation system caused by the seedling water body. The specific method is to set nozzles at a certain distance around the seedling pond. The seawater ejected from the nozzle is the water flow that makes the seedling water run (Jin Qizeng...
