Embodiment 1

[0019] Location: Zhanhai shrimp nursery farm in Wushi, Zhanjiang. Time: April 2005. 150 golden-yellow shell-colored individuals, 1.5-2.0 years old, were selected from Zhanjiang Liusha Port and Houhonghai area. The average shell length of the breeding population was 6.35. ±1.12cm. Indoor maturation promotion cultivation, changing water once a day, and feeding enough chlorella and flat algae. After 7 days, the parents developed to a physiologically mature state. During the ripening period, the water temperature is 24°C and the salinity is 30‰. After 20 minutes of drying in the shade, the parents discharge gametes, filter the male and female gametes with a 300-mesh sieve, put them into 30L plastic buckets, add 20L seawater at the same time, then add a small amount of mixed sperm into the bucket containing the female gametes, and stir well. artificial insemination. Fertilized egg hatching and post-cultivation were carried out according to conventional techniques. During the gr...

Embodiment 2

[0021] Location: Guangdong Anhua Group Co., Ltd., Xuwen, Zhanjiang, Time: March 2008, according to the targets of shell color and shell weight index, the 3rd generation population selection was carried out on the breeding population. From the golden shell color selection series F 2 1000 individuals with obvious golden shell color characteristics were randomly sampled, 1.2 years old, and 80 individuals were selected as parents according to the shell color, and the line F was selected. 2 The average shell weight index was 19.63±2.61, and that of the parents was 21.12±1.34. Indoor maturation promotion cultivation, changing water once a day, and feeding enough chlorella and flat algae. After 7 days, the parents developed to a physiologically mature state. During the ripening period, the water temperature is 25°C and the salinity is 30‰. After 20 minutes of drying in the shade, the parents discharge gametes, filter the male and female gametes with a 300-mesh sieve, put them into...

Abstract

The invention discloses a seed production method for breeding pinctada martensii, which comprises the following steps: selecting individuals with obvious characteristic of golden yellow shell color from wild or bred colonies as parents to perform colony sex so as to establish basic colonies; performing colony selection on the basic colonies according to the characteristics of shell color and shell weight index; and after the selection of 3 to 5 generations, selecting the colonies in which the proportion of the golden yellow shell individuals can reach 95 percent and the shell weight index is improved by over 20 percent. The method for breeding a new pinctada martensii strain with obvious characteristics of shell color and shell weight index by using the golden yellow shell individuals of the wild or bred colonies as parents has stronger operability and can realize industrialized production.

Description

technical field [0001] The invention relates to a seed production method for cultivating Pinctada martensii. Background technique [0002] Pinctada martensii (Dunker) is one of the main economic shellfish in Guangdong, Guangxi and Hainan provinces in southern my country. The main purpose of culturing Pinctada martensii is to cultivate seawater pearls. In my country, the pearls cultivated by using Pinctada martensii are known as "Southern Pearls". They are well-known both at home and abroad for their delicateness, embellishment of pearl gardens, magnificence and colorfulness, and long-lasting luster. [0003] In 1965, the artificial breeding of Pinctada martensii in my country was successful. So far, Pinctada martensii has been cultured artificially for more than 40 years. Due to long-term inbreeding and other reasons, there have been serious problems such as precocious puberty and smaller shell bodies; the breeding density in many sea areas is too high, and the breeding e...
