specific Embodiment approach 1

[0018] Specific embodiment one: a kind of pure line yellow barb seed production method of the present embodiment, it is to carry out according to the following steps:

[0019] 1. Collect wild silver-gray barb from natural waters and cultivate it for 3 to 4 years until the gonads mature;

[0020] 2. Carrying out artificial induction, insemination and hatching of the gonad-matured female and male wild giant barbs in the previous step to obtain F1 silver-gray individuals; carry out the next step of the obtained F1 silver-gray individuals;

[0021] 3. Raise the silver-gray F1 individuals obtained in the above steps in ponds and cultivate them for 4 to 5 years until the gonads mature;

[0022] 4. Adopt inbreeding of offspring of the same parents, artificially induce labor, insemination and hatch the F1 female and male fish with mature gonads in the previous step, and obtain F2 by self-breeding of silver-gray F1;

[0023] 5. After F2 is cultivated in ponds to reach 2-3 cm, separate...

Description

technical field [0001] The invention relates to a seed production method of pure-line yellow barb. Background technique [0002] Barbus capito, belonging to Cyprinidae, Barbae subfamily, and Barbus genus, is mainly distributed in the Caspian Sea and Aral Sea in West Asia and the rivers flowing through it. It is a rare large-scale economic fish in the local area. The body length of this fish can reach 70cm, and the weight is 12kg. It has excellent characteristics such as high salt-alkali tolerance, wide appetite, delicious meat, and fast growth. There is no artificial breeding research abroad, and it is still in the wild primitive state in natural waters. In 2003, with the support of the "948" project of the Ministry of Agriculture, the wild giant barb was introduced from Uzbekistan for the first time in China. After more than ten years of research and experiments by the researchers of the Heilongjiang Fisheries Research Institute, it was the first time that the fish was full...
