Problems solved by technology

[0003] At present, there is a small amount of artificial breeding of Chinese sand loach in Sichuan Province, but the scale is small, and the artificial breeding technology is not mature, especially the cases of mature breeding in the circulating water system and successful artificial induced breeding have not been reported. The main reason is that the male fish The amount of semen is very small, and the male fish is often checked for semen extraction before artificial insemination. When insemination, the male fish can only squeeze out 1-2 drops of semen or no semen at all, resulting in a low or low fertilization rate. Completely impermeable, resulting in the failure of artificial reproduction, which is one of the important reasons for the failure of large-scale production

Embodiment 1

[0031] The method for artificial propagation of Chinese loach, the steps are:

[0032] 1. The domestication method of Chinese loach:

[0033] 1) Domestication of wild broodstock

[0034] A. From August to December 2013, more than 500 wild Chinese loach parents were collected in the waters of the Jinsha River in Panzhihua, Sichuan Province, and transported to the fish breeding station of Datang Guanyinyan Hydropower Station for temporary breeding;

[0035]B. After arriving at the station, carry out the water temperature transition first, and put the collected wild Chinese loach into the breeding tank together with the oxygen bag. At that time, the water temperature in the tank was 22°C, and the water temperature of the oxygen bag containing the fish was about 15°C. When the water temperature in the oxygen bag rises to about 21°C, pour the fish from the oxygen bag into a square box, select the broodstock with strong physique and light injuries, and put them in the broodstock br...

Embodiment 2

[0055] The method for artificial propagation of Chinese loach, the steps are:

[0056] 1. The domestication method of Chinese loach:

[0057] A. From March to June 2014, more than 200 wild Chinese loach parents were collected in the waters of the Jinsha River in Panzhihua, Sichuan, and transported to the fish breeding station of the Datang Guanyinyan Hydropower Station for temporary breeding;

[0058] B. After arriving at the station, carry out the water temperature transition first, and put the collected wild Chinese loach into the breeding tank together with the oxygen bag. At that time, the water temperature in the oxygen bag was 12°C, and the water temperature in the breeding tank was 16°C. The water temperature in the bag rises to about 15°C. At this time, pour the broodstock in the bag into a square plastic box, screen 180 broodstock with strong physique and light injuries, and put them into a broodstock cultivation tank with a diameter of 2 meters for temporary feeding....

Embodiment 3

[0077] The method for artificial propagation of Chinese loach, the steps are:

[0078] 1) Domestication of wild broodstock

[0079] A. From August to November 2015, more than 100 wild parents were collected by nets in the waters of Jinsha River in Lijiang, Yunnan, and transported to the circulating water system of the fish breeding station of Hanergy Jin'anqiao Hydropower Station for temporary breeding.

[0080] B. After arriving at the station, the water temperature is transitioned, and then screened to select individuals with strong physique and light injuries, and put them in a broodstock breeding tank for temporary breeding and isolation treatment. The treatment method is to bathe with 2-3% salt and 200ppm penicillin for 20-30 minutes, then change the water and soak in 20ppm enrofloxacin solution for 24 hours, then change the water, then soak in 0.5ppm methylene blue solution for 24 hours to prevent Water mold grows.

[0081] C. Start baiting after the fish wounds and ac...

Abstract

The invention discloses an artificial propagation method for botia superciliaris. The method comprises the following steps of 1 wild parent fish collecting and domesticating, 2 parent fish breeding, 3 artificial spawning, 4 artificial inseminating and 5 artificial incubating. The method is simple, high in operability and good in practical applicability, large-scale and industrialized production of botia superciliaris fries can be achieved, development of botia superciliaris breeding industry is promoted, and botia superciliaris wild resources are effectively protected. Tests show that the survival rate of the botia superciliaris bred in a circulating water system ranges from 80% to 85%, the induced spawning rate ranges from 70% to 75%, the fertilization rate ranges from 40% to 45%, and the incubating rate ranges from 70% to 80%.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an artificial propagation method of Chinese loach. Background technique [0002] Chinese sand loach (scientific name: Botia superciliaris), commonly known as "Chuan Jinmei" in the south, is a fish belonging to the genus Botia superciliaris and is endemic to China. Small fish, body length 9-18cm, slender body, bright body color, beautiful markings on the body surface; long and pointed snout, 3 pairs of whiskers, 1 pair of button-like protrusions under the chin; barbs behind the eyes, the end exceeds Posterior edge of eye; without scales, end of pelvic fin not reaching anus, anus near origin of anal fin, caudal peduncle lower. Chinese loach is distributed in the Nanxi River and Lancang River in Yongjia, Wenzhou, the eastern Sichuan Basin and the low mountainous areas around the basin. It is also distributed in Yichang, Hubei, and Wenxian County, Gansu. It has high ...
