Problems solved by technology

[0003] The purpose of the present invention is to provide an optimized incubation method for pearl shellfish seedlings, to overcome the low hatching rate of traditional pearl shellfish seedlings natural hatching and laissez-faire cultivation, the quality of seedlings degrades, the cultivation quality is low, and the quality of pearl oysters is low. Poor, small size, poor disease resistance

Embodiment 1

[0017] (1) Collection of parent shellfish: In the first ten days of April in the spring of that year, 2,000 wild 3-year-old Fritillaria martensii species were collected in the Beibu Gulf sea area. The shells are complete, the shell height is more than 7cm, the radiation is obvious, the scales on the abdomen are prominent, and there is no infection by diseases and insect pests. , the nacre on the inner wall of the shell is crystal clear and smooth, silvery white or iridescent in color, and the gonads of Pinctada martensii are artificially inseminated as brood shells; the mature female gonads are bright yellow or light yellow in appearance, full of gonads, smooth in surface, random Choose ten broodlings, pick a few mature eggs on a glass slide, drop them into sea water and see them disperse, mature eggs under a microscope, egg diameter is 50 microns-60 microns, egg nucleus is large and obvious, yolk grains are rich and mature; male The appearance of the gonads is milky white, the...

Embodiment 2

[0033] (1) Collection of parent shellfish: In early September of that autumn, 2,000 wild 5-year-old Fritillaria martensii species were collected in the Beibu Gulf sea area. , the nacre on the inner wall of the shell is crystal clear and smooth, silvery white or iridescent in color, and the gonads of Pinctada martensii are artificially inseminated as brood shells; the mature female gonads are bright yellow or light yellow in appearance, full of gonads, smooth in surface, random Select ten broodlings, pick a few mature eggs on a glass slide, and drop them into sea water to see them disperse. Under the microscope, the mature eggs have a diameter of 50 μm-60 μm, large and obvious nucleus, rich and mature yolk grains; appearance of male gonads It is milky white, the surface of the gonads is rough and granular, germ cells flow out near the genital pores when lightly pressed, the semen is milky, mature sperm are very active when observed under a microscope in 30mg / L-50mg / L ammonia sea...

Abstract

The invention discloses an optimized hatching breeding method for pinctada martensii seedlings. The method comprises the following steps of collection of parent pinctada martensiis, preparation beforeinsemination, parturition hastening through induction, insemination, hatching, trochophore collection and temporary breeding, larva breeding, prevention and treatment for insects and diseases, seedling adhering and seedling collection. According to the method, wild original strains are collected as the parent pinctada martensiis, by adjusting the seawater PH value and salt degree of breeding liquid, a good environment suitable for propagation of pinctada martensiis is created, and in the insemination process, the scientific proportion of ova to sperms is adopted; egg cells which are not subjected to insemination, excess sperm cells and remaining tissue cells are timely removed, the hatching water quality of the pinctada martensiis is effectively improved, the ovum washing time of the pinctada martensiis is shortened, the hatching density of oosperms is increased, and therefore the hatching rate is increased. The hatched and bred pinctada martensii seedlings are strong, the variety isgood, the breeding survival rate is high, the method is easy to implement, and the economic benefits are high.

Description

technical field [0001] The invention relates to an optimized hatching and cultivation method for pearl oyster oysters martensii seedlings, which belongs to the technical field of seawater pearl cultivation. Background technique [0002] my country is a big country rich in pearls, and the South Pearl produced is famous both at home and abroad. It is known as "the West Pearl is not as good as the East Pearl, and the East Pearl is not as good as the South Pearl". Nanzhu refers to the pearls produced in the Beibu Gulf, that is, the pearls cultivated from the Martensii pearl oyster, especially the pearls produced in Hepu, Guangxi. The pearls produced in Hepu are dignified in quality, bright and clean, round and colorful, and are the best among pearls. It stands to reason that such a good pearl should have a good international reputation and a good international market, but the facts are not optimistic. my country's pearl sales in the international market account for less than 10...
