Cultivation method of novel strain of crassostrea gigas with pure purple left shells

Abstract

The invention discloses a cultivation method of a novel strain of crassostrea gigas with a pure purple left shells. The cultivation method is characterized in that operation comprises the steps of: (1) seed production: selecting male and female individuals with pure purple left shells from a cultured group as cultivating parent shellfishes; performing one-to-one insemination and copulation, respectively marking breeding systems, cultivating larva by adopting strict isolation measures, and placing in a same sea area for intermediate culture and cultivation; breeding generation by generation to purify so as to form a family; and (2) purification of the novel strain: selecting inseparate families with character proportion of above 90% as parent shellfishes, performing seedling propagation so as to cultivate the novel strain of crassostrea gigas with the pure purple left shells and stable character. With the adoption of the cultivation method provided by the invention, the cultivating process of the novel strain is accelerated and transgenic and pharmaceutical treatment do not need to be carried out, the novel strain is cultivated, the additional value of product is also improved through color character, and the market sale price and income of cultivation enterprises and cultivators are increased, and market prospect is wide.

Description

technical field [0001] The invention relates to a selective breeding technique in the genetic breeding of shellfish, in particular to a method for cultivating a new strain of the left shell pure purple long oyster. Background technique [0002] The long oyster belongs to the mollusk Phylumbranchia, and the genus Pysteraceae of the family Oysteridae of the order Pearl Oyster. Long oysters are tender and can be eaten fresh or dried. Oyster soup can be condensed into oyster sauce. The long oyster is naturally distributed in Japan, China and Korea, and is the most widely cultivated and produced marine shellfish in the world. my country's oyster production accounts for more than 80% of the world's oyster production, mainly oysters. [0003] As an important economic trait, color has always been concerned by geneticists and breeders because of its stable heredity. This trait has been applied in agriculture, animal husbandry and fish genetic breeding. In shellfish, shell color, ...
