Embodiment Construction

[0031] The present invention will be further described below in conjunction with specific examples, so that those skilled in the art can better understand and implement the technical solutions of the present invention.

[0032] A kind of ovoid pomfret body quality breeding method based on Gompertz model, comprises the following steps:

[0033] (1) Construct a selective breeding population of ovate pomfret, carry out nutritional enhancement of broodstock and gonad stimulation to induce production, obtain fertilized eggs, and then carry out offspring seed cultivation and sea area culture. Specific steps are as follows:

[0034] The F3 individuals of the ovoid pomfret breeding population were used as candidate parents. During the first two months of the breeding season, fresh squid, miscellaneous fish, bonito and multivitamins were mixed and fed to strengthen the nutrition of the broodstock and stimulate the maturation of the gonads. Chorionic gonadotropin (HCG), ovulation-stimu...

Abstract

The invention provides a body mass breeding method for pomfret ovata based on the Gompertz model, which measures the multiple body weight data of the breeding population of pomfret ovata, establishes the Gompertz model of the body weight of each fish, and calculates the body mass of each fish Based on the optimal value of body weight growth rate, combined with the additive genetic correlation matrix constructed by microsatellite markers, the breeding value of body weight growth rate of each fish is calculated, and candidate parents are selected according to the breeding value of body weight growth rate, and candidate parents are designed The mating program, to complete the body quality breeding of oval pomfret. The method of the invention can breed a new fast-growing strain of the oval pomfret, avoid inbreeding, and improve breeding efficiency.

Description

technical field [0001] The invention belongs to the technical field of aquatic animal breeding, and relates to a method for breeding oval pomfret body quality based on a Gompertz model. Background technique [0002] Oval pomfret (Trachinotus ovatus), commonly known as golden pomfret, yellow wax pomfret, and red three yellow wax pomfret, is a warm-water, eurysalin, and migratory fish. It is widely distributed in tropical and subtropical seas such as the South my country Sea, Indian Ocean, and Mediterranean Sea. Belonging to carnivorous fish, its group feeding behavior is fierce, and it can eat commercial compound feed with suitable caliber after domestication. Oval pomfret is a high-quality seawater edible fish with rapid growth, tender meat, delicious taste and high economic value. It has become one of the important marine fish culture species in coastal areas such as Guangdong, Guangxi and Hainan. However, with the continuous expansion of its breeding scale, problems such a...
