Problems solved by technology

[0003] Zhejiang Qingxi Soft-shelled Soft-shelled Turtle Industry Co., Ltd. has been in the exploration stage since 1992, when the soft-shelled soft-shelled soft-shelled turtle was raised on trial, mainly because the genetic traits of the soft-shelled soft-shelled turtle were not stable

Embodiment Construction

[0015] 1. Systematic selection of black soft-shelled turtle parents

[0016] ①Choose a black soft-shelled soft-shelled soft-shelled turtle, which is extremely rare in nature, and crosses it with the soft-shelled soft-shelled soft-shelled turtle to produce F 1 .

[0017] ② in F 1 Select black turtle individuals with all black traits for selfing, and produce F 2 .

[0018] ③ in F 2 Select individuals with all black traits and then self-cross to produce F 3 .

[0019] ④ in F 3 Select individuals with all black traits and continue selfing to produce F 4 . After four generations of selective breeding, the genetic characters of the soft-shelled soft-shelled turtle have stabilized to more than 99%.

[0020] 2. Parental cultivation

[0021] Use F 4 Breed as parents, the male to female ratio of the parents is 6:1, and the stocking density is 2m 2 / fish, fresh animal bait accounts for 60% of the feeding material, 40% of the bait is mainly imported white fish meal, and diseas...

Abstract

The invention relates to the field of the aquiculture, in particular to methods of the breed selection of the soft-shelled turtle breed-parent and the breeding of the soft-shelled turtle. The breed selection of the soft-shelled turtle includes obtaining F1 by crossbreeding of the soft-shelled turtle individual and the strip-necked turtle; obtaining the soft-shelled turtle breed-parent F4 after breed selection of three generations, the genetic character thereof is stable at above 99%. The invention also discloses the breeding of the soft-shelled turtle, which includes introducing and breeding F4 as the breed-parent; egg-laying, egg taking, incubating, temporarily breeding of young turtles, breeding of baby turtles, stocking in the outer pond and obtaining the soft-shelled turtle. The bred soft-shelled turtle is characterized in good taste, good mouth feeling and high nutritive value.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a breeding method for the black turtle parent and a breeding method for the black turtle. Background technique [0002] The black turtle is produced in the Taihu Lake Basin, and it is also called "tile turtle" locally. Its whole body and even its belly are pitch-black, and its shape is similar to that of a common soft-shelled turtle. It is rare to see one among thousands of wild soft-shelled turtles. Relevant information shows that Japan's University of Tokyo and Iwatani Industrial Corporation have conducted research to confirm that "turtle has anti-cancer effects". Because the turtle body contains vitamin B17, especially the content in the skirt is relatively rich, and vitamin B17 is an anti-cancer substance recognized by the United Nations Health Organization. According to the inventor's research, the content of vitamin B17 is relatively high in animals with melanin, so the content...
