Embodiment 1

[0022] Step 1: The source of parent shellfish is Shenzhen wild Pinctada martensii Dunker (Pinctada martensii Dunker), the number is 2,000, and the color of the shell surface is golden yellow. Use a mouther to open the shell to a size of about 0.5cm-1cm, and check the front ear. The color of the mantle border, select the individuals whose mantle border is golden yellow. Select individuals with fuller glands from the selected individuals, and the shellfish age is 2 years old; they are kept indoors for 5 days, and the water temperature is above 25°C, and they are cultured at room temperature. During the breeding period, the water is changed once a day, and sufficient bait is fed to promote the further development of the gonads into a physiologically mature state. The fertilization adopts single crossing, and the sperm eggs are respectively drawn into the beaker filled with filtered sea water, and the collected sperm eggs are filtered through a sieve to remove impurities and tissu...

Abstract

The invention discloses a method for producing seeds of golden shell colored pinctada martensii. The process for studying genetic breeding of pinctada martensii discovers that the characters of golden shell surface and golden pallial edge can be inherited, so that pinctada martensii having golden lip (the pallial edge is golden) and golden shell appearance can be easily cultivated, the proportion of golden shell color can be more than 60 percent without transgenosis or chemal treatment and other complicated technologies, and the product does not influence biological and environmental safety. According to the golden shell colored pinctada martensii, the death rate and pearl yield of pearly shellfish can be reduced, and the economical benefit of the product can be increased.

Description

[0001] Technical field: [0002] The invention belongs to the field of aquatic animal genetic breeding technology and aquaculture, and in particular relates to a seed production method of golden-yellow shell-colored Pinctada martensii. [0003] Background technique: [0004] Studies have shown that there is a certain correlation between the individual's choice of shell color in the growth process and its growth environment (including the temperature and salinity of the water area, etc.), geographical location and physiological factors. According to some shellfish research reports, shell color polymorphism is a simple Mendelian inheritance, but there is no clear conclusion whether the selection of shell color is necessarily related to growth traits, physiological traits and some economic traits. [0005] Pinctada martensii Dunker (Pinctada martensii Dunker) belongs to Bivalvia, Pearl Oysteraceae, and Pinctada genus. It is an important cultured seawater pearl shellfish. Its shell...
