Problems solved by technology

However, the main problems at present are: small seed production capacity, too scattered seed production, poor equipment, low efficiency; low seed quality, resulting in damage to the interests of farmers, which is extremely inconsistent with the increase in the demand for strains for production development To a large extent, it restricts the development of aquaculture production

Embodiment 1

[0026] 1. Artificially cultivated parents: 1) Egg selection: Select fertilized eggs with a diameter of more than 2 cm and a weight of 3-7g from the eggs laid by the ancestors of the parent turtles. Eggs are artificially hatched after being marked in different spawning pools, and the priority rate of eggs is controlled at 60%; 2) hatchling breeding: select healthy, energetic, strong limbs, and no deformities from the hatched hatchlings. Individuals, juvenile turtles with a weight of more than 4g are marked according to different sources after disinfection, and they are cultivated under different conditions, and the selection rate is not higher than 60%. Glossy, thick skirts, consistent specifications, turtles weighing more than 15g, the selection rate is not higher than 60%; 4) Reserve parent turtle selection: After the selected young turtles grow to a weight of more than 200g after breeding, then select none according to their external characteristics. Injuries, large individu...

Embodiment 2

[0033] 1. Establish a parent system: 1) Select wild parents for fishing. Specific selection criteria for parents: strong physique, no injuries on the surface, bright body color, smooth skin, sound limbs, no disease or injury, quick movements; The mature age is over 5 years old, the female tortoise is more than 1kg, the male tortoise is 500g, and the ratio of female to male is 3-2.5:1; 2) Supplementation of backup parents: 30% of the parental individuals used for breeding will be eliminated every year. Parents, including parents with injuries, physical degradation and breeding years of up to 4 years; the eliminated parents are supplemented by wild parents; 3) parent breeding: select the parents caught outside each year according to the breeding standards, and mark the qualified ones , and reared in separate ponds; the cultivation of the parents is carried out in the outdoor parent cultivation ponds, the density of the parents is 1-2 fish / square meter, and the ratio of female to ...

Embodiment 3

[0038] Embodiment 3: adopt the mode that raises together with fish

[0039] 1. Artificially cultivated parents: 1) Egg selection: select fertilized eggs with a diameter of more than 2 cm, a weight of more than 8 g, bright and clean color, and a clear periphery from the eggs laid by the ancestral soft-shelled turtles. Carry out artificial hatching after marking according to different spawning pools, and the priority rate of eggs is controlled at 60%; 2) juvenile soft-shelled turtle breeding: select healthy, energetic, strong limbs, and no-deformed individuals from the hatched juvenile soft-shelled turtles , Juvenile soft-shelled turtles weighing more than 6g, after disinfection, mark according to different sources, and carry out cultivation under different conditions respectively, the selection rate is not higher than 60%; 3) Juvenile soft-shelled turtle breeding: after the juvenile soft-shelled turtle cultivation stage, select the ones with complete appearance and shiny skin ,...

Abstract

The present invention relates to a breeding method for tortoises, comprising the following steps: A, establishing a parent system: 1) selecting parents; 2) supplementing backup parents; 3) cultivating parents; B, hatching; C, cultivating young turtles and soft-shelled turtles; D. Cultivation of young turtles and soft-shelled turtles; E. Breeding of commercial turtles and soft-shelled turtles. The present invention adopts green ecological breeding, realizes the integration of production, epidemic prevention and sales, and continuously develops all links of the industry. Starting from the cultivation of seedlings, it not only ensures the emergence rate, but also ensures the quality of seedlings, laying a solid foundation for later breeding and breeding. a good foundation. In the present invention, the parental generation of the turtle is the offspring of the ancestor's parental turtle, and the breeding process starts from the eggs to serve as the parents' parental fish and turtles, and will go through egg selection, juvenile turtle selection, young turtle selection, and backup parents. Turtle breeding, breeding of turtles and turtles, etc. The purity of parent turtles and soft-shelled turtles and the excellent traits of the germplasm are ensured through layers of checks and optimizations in the breeding of parent turtles.

Description

technical field [0001] The present invention relates to special aquaculture, in particular to a breeding method for turtles. Background technique [0002] In recent years, while the aquaculture industry has maintained rapid development, famous and special aquaculture has sprung up, the enthusiasm for breeding has been high, and the breeding boom has been set off in various places. Driven by the market and interests, famous and special aquaculture has formed a relatively large scale , its products have a certain batch, which has played an important role in promoting the structural adjustment of the aquaculture industry and increasing the income of the majority of farmers. Following the continuous development of mandarin fish, snakehead, river crab, and catfish, the breeding of turtles, yellow catfish, and squid has developed rapidly. Because turtles are high-quality special aquatic products with delicious taste, they are popular in restaurants and homes, and the market price...
