Embodiment Construction

[0018] (1) F1 generation selection:

[0019] 1. Monogamous fertilization and hatching: In 2009, individuals with a pure purple left shell and a black mantle were selected from the oyster breeding population as male breeding broodstock, and the left shell was pure black and the mantle was black. Black individuals are used as female breeding broodstock, and they are divided into groups and mated in single pairs, that is, one female and one male are mated to establish families respectively; the fertilized eggs of each group are placed in 100L polyethylene plastic buckets filled with filtered seawater and made Well-marked, micro-inflated, hatching density controlled at 20-40 / ml, and hatched to D-shaped larvae after 18-20 hours at a water temperature of 20-24°C;

[0020] 2. Cultivation of larvae: Use the siphon method to select the above-mentioned D-shaped larvae with a 300-mesh silk screen, and place them in 100L polyethylene plastic buckets for cultivation; adjust the cultivation...

Abstract

The invention discloses a breeding method for a new strain of crassostrea gigas with orange left and right shells. The breeding method comprises the following steps of selecting individuals with purple left shells and black palliums from a cultured population to be used as male reproduction brood stocks; selecting individuals with black left shells and black palliums to be used as female reproduction brood stocks; carrying out monogamous insemination to establish an F1 family; selecting female and male individuals with black left and right shells and black palliums from the F1 to be used as reproduction brood stocks and establishing an F2 family; continuously selecting female and male individuals with purple black left and right shells and black palliums from the F2 to be used as reproduction brood stocks and establishing an F3 family; selecting orange individuals as parents of the new strain from the F3 and propagating offspring seeds to culture the new strain of the crassostrea gigas with the orange left and right shells and stable characters. The additional value of products is improved and the market prospect is broad.

Description

technical field [0001] The invention relates to a family selection breeding technique in the genetic breeding of shellfish, in particular to a method for breeding a new strain of long orange oyster. Background technique [0002] The long oyster, also known as the Pacific oyster, belongs to the mollusk Phylumbranchia, Pearl Oyster, Oysteridae, and the genus Pyramid. It has the advantages of strong environmental adaptability, fast growth, delicious flavor, and rich nutrition. It is the most extensively cultivated, The most productive economical shellfish. Long oyster is the world's largest cultured shellfish. Most of the seedlings required for cultivation rely on artificial seedlings. The parents used for seedlings are all wild-type populations that have never been genetically improved. [0003] As an important economic trait, color has always been concerned by geneticists and breeders because of its stable heredity. In wild populations of long oysters, individuals with blac...
