Embodiment 1

[0027] A method for hybrid breeding of Siberian sturgeon female fish and Stryker's sturgeon male fish, the steps of the method are as follows:

[0028] 1. Parental selection: female parent selection 5 + Siberian sturgeon, the male parent was 7 + Sturgeon Sturgeon;

[0029] 2. Breeding and reproductive regulation of broodstock:

[0030] (1) Selection of broodstock: Select Siberian sturgeon female broodstock with normal body color, large size, healthy body and more than 5 years of age, with a total length of 100-125cm and a weight of 7.5-15kg; male Siberian sturgeon over 7 years old , with a total length of 135-160cm and a weight of 15-20kg; put the optimal broodstock in batches into circular broodstock breeding ponds with a diameter of 15m, the ratio of male to female is ♀:♂=1.5:1; the stocking density is 20kg / m 3 ;

[0031] (2) Broodstock feeding and nutrition intensive cultivation: feeding of broodstock: 2 times a day, the daily feeding amount is 1.2wt.% of the fish body ...

Abstract

The invention relates to a hybrid breeding method for a female Siberian sturgeon and a male Amur sturgeon and belongs to the technical field of aquaculture. The method includes the following steps that 1, choice of parents is conducted, wherein a 5+ aged Siberian sturgeon is selected as the female parent, and a 7+ aged Amur sturgeon is selected as the male parent; 2, parent fish breeding and procreation regulation are conducted, wherein parent fish optimization, parent fish feed selection, feeding and nutrient enrichment, water temperature procreation regulation and breeding condition and daily management are conducted; 3, artificial fertilization and hatching are conducted, wherein spawn squeezing and semen collection, artificial fertilization, spawn washing and hatching of fertilized spawns are conducted; 4, breeding of fish larvae and young fishes is conducted. The hybrid sturgeon fry bred through the method are high in fertility rate and hatching rate and have the advantages of being high in growth speed, wide in adaptability, high in stress resistance, good in growth trait and the like, and the method is suitable for breeding sturgeons in different regions of China.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for cultivating new species of sturgeon and realizing large-scale breeding of fine species, hybrid seedlings with high fertilization rate and hatching rate, and a hybrid breeding method for female Siberian sturgeon and male Sturgeon's sturgeon. Background technique [0002] At present, my country has become the world's largest sturgeon breeding country, with an annual output of about 21,000 tons, accounting for 89% of the world's sturgeon farming output. With the rapid development of our country's sturgeon aquaculture industry, problems such as the confusion of hybrid breeding species and the lack of good breeding species have become increasingly prominent, which seriously restricts the healthy development of our country's sturgeon industry. At present, most of the sturgeon cultured species in my country are wild domesticated species, and the cultured species are chaot...
