Problems solved by technology

In natural waters, because the parents of red-eyed trout are small, their egg production is relatively small. In addition, due to the fluctuation of hydrology in natural waters, the survival rate of hatched red-eyed trout fry is low

Embodiment 1

[0022] The artificial propagation method of red-eye trout includes the following steps:

[0023] (1) Before January, 150kg / mu of quicklime was used to sterilize the broodstock cultivation pond of red-eye trout, and 1.2m deep water was injected, 250kg of fermented chicken manure was applied per mu to cultivate water quality, and the broodstock of red-eye trout over 2 years old was 150kg / mu·m; water temperature At 11~20℃, the feed is artificial feed, which is fed twice a day, and the daily feed amount is 2% of the total weight of the surviving broodstock in the pond; when the water temperature is 14~20℃, artificial feed is fed 2 times a day The daily feeding amount of artificial feed is 2% of the total weight of the surviving broodstock in the pond, and the daily feeding amount of green feed is 20% of the total weight of the surviving broodstock in the pond. After entering the pond, the cultivation pond shall be filled with water once every 15 days, with water filling of 10cm each ...

Embodiment 2

[0030] The artificial propagation method of red-eye trout includes the following steps:

[0031] (1) Before January, 150kg / mu of quicklime was used to sterilize the broodstock cultivation pond of red-eye trout, and 1.2m deep water was injected, 250kg of fermented chicken manure was applied per mu to cultivate water quality, and the broodstock of red-eye trout over 2 years old was 150kg / mu·m; water temperature At 11-20℃, the feed is artificial feed, once a day, the daily feed is 0.5% of the total weight of the surviving broodstock in the pond; when the water temperature is 14-20℃, artificial feed is fed 1 day The daily feeding amount of artificial feed is 0.5% of the total weight of the surviving broodstock in the pond, and the daily feeding amount of green feed is 10% of the total weight of the surviving broodstock in the pond. In order to meet the needs of the development of the gonads of the broodstock of red-eye trout, the broodstock After entering the pond, the cultivation po...

Abstract

The invention discloses an artificial propagation method for squaliobarbus curriculus, which comprises the following steps: 1, putting the squaliobarbus curriculus into a processed farming pool, feeding artificial diet in combination with green fodder, wherein the squaliobarbus curriculus includes male squaliobarbus curriculus parent fish and female squaliobarbus curriculus parent fish; in the mid-to-late May, respectively injecting artificial oxytocic into the squaliobarbus curriculus parent fish and the female squaliobarbus curriculus parent fish for hastening parturition; and 3, allowing roes and male sperms to be subjected to artificial insemination, then moving fertilized eggs into a 5 percent normal saline for mixing, immersing in yellow mud water and cleaning for 3-5 times for debonding, and putting the fertilized eggs into an incubation cylinder or a concrete incubation ring for water incubation. According to the invention, the artificial oxytocic is adopted for hastening parturition, so that the fertility of the squaliobarbus curriculus is effectively improved, and as artificial insemination and artificial propagation way is adopted, the fertility rate and the survival rate of incubation of the fertilized eggs are both improved.

Description

Technical field [0001] The invention relates to an artificial propagation method of red eye trout. Background technique [0002] Crimson trout belongs to the genus Cypriniformes, Cyprinidae, Yalu subfamily, Trichogramma. It is commonly known as redeye and wild grass fish in Zhenjiang, Jiangsu. It is distributed in various water systems throughout the country. It is a fast growing, adaptable, food miscellaneous, commodity High-value economic fish. [0003] Red eye trout grows fastest in the second to fourth instar stage, and the common individuals can reach 0.5 to 1.5 kg. In general, red-eye trout is mature at second instar. The period from mid-May to early June in Zhenjiang area of ​​Jiangsu Province is the peak spawning period for the broodstock of red-eye trout, and its eggs are sticky eggs. In natural waters, due to the small individuals of the C. eye trout parents, their spawning volume is relatively small. In addition, due to the variable hydrology of natural waters, the sur...
