Embodiment 1

[0028] experimental method

[0029] The parents of Oriental Plateau Loach were captured from the Yarlung Zangbo River and transported to the aquaculture base of Tibet Agriculture and Animal Husbandry College in Linzhi, where they were disinfected with 10 mg / L potassium permanganate for 10 minutes.

[0030] Select 20 individuals with large females, soft and elastic abdomen, red and swollen genital pores, body length of 12cm, and weight of 13g or more; select males that are larger, with obvious secondary sexual characteristics in the muzzle and pectoral fins, thick pads and spines , And 10 individuals with a body length of 10 cm and a weight of 11 g or more were kept temporarily in a cage of 0.6 × 0.5 × 0.6 m.

[0031] Choose chorionic gonadotropin (HCG), luteinizing hormone releasing hormone analog A 2 (LHRH-A 2 ) And dioscillate (DOM), the female fish's inducing dose is HCG2000IU / kg, LHRH-A 2 25μg / kg, DOM6mg / kg, male fish dose halved.

[0032] Begin artificial induction of labor. Befo...

Abstract

The invention relates to the field of aquatic culture and discloses an artificial breeding technology for Oriental loaches. The artificial breeding technology comprises the following steps of (1) selecting parents, (2) selecting laboring induction drug and laboring induction drug, (3) artificially laboring inducing, (4) artificially inseminating and (5) hatching, wherein mature Oriental loach individuals with normal color, moderate conduction factor and excellent gonad development are chosen as parents; chorionic gonadotropin, luliberin analog A2 (LHRH-A1) and DOM are selected for labor induction drug; the raun laboring induction dosage is HCG of 2000 to 25000IU / KG, LHRH-A1 of 225 to 30 [mu]g / kg and DOM of 6 to 8 mg / kg; milter dosage is reduced by half; with the temperature of 15 to 17 DEG C, the miter is injected 6 to 10 hours after the raum is injected; the raum is artificially inseminated 42 to 60 hours after the raum is injected; and the hatching time is 62 to 80 hours at the temperature of 15 to 19 DEG C.

Description

Technical field [0001] The invention relates to the technical field of aquaculture, in particular to an artificial propagation technology of Oriental Plateau Loach. Background technique [0002] The Oriental Plateau Loach Triplophysaorientalis (Herzenstein), the local name Hemp, belongs to Cypriniformes, Loach, Loach subfamily, and Plateau Loach. It is mainly distributed in Tibet's Lhasa River, the upper reaches of the Nu River, Qinghai, Gansu and the Yangtze River in western Sichuan. The main stream of the Yellow River and its affiliated water bodies, the artesian water bodies of the Qaidam Basin in Qinghai and the Hexi Corridor of Gansu. The Oriental Plateau Loach is a larger individual in the Tibetan Plateau Loach genus, with a body length of 56.5-142mm, which has certain economic value, and has beautiful patterns on the surface, which has good ornamental properties. Plateaus including the Oriental Plateau Loach Loach is an important indigenous fish in the waters of the Yarlu...
