Problems solved by technology

[0005] In order to solve the problems of insufficient supply of broodstock, asynchronous sexual maturity, non-concentrated spawning time, and low hatching rate, the purpose of the present invention is to propose a full-artificial propagation method for cultivating smooth-lipped fish, which is based on on-site The juveniles of wild eucalyptus were domesticated and cultivated to sexual maturity, and ex

Embodiment

[0017] In the middle and late July of 2014, juvenile fish were collected from Huixi River, Xiuning County, the source water system of Qiantang River, and the natural reproduction rate was 50 fish / m 2 The density belt water is quickly transferred to the cement cultivation pool with a size of 6.0m×4.0m×1.2m, and the water depth is kept at 50-60cm. In the initial stage, the powdered compound feed with a protein content of 42% and ultrafine grinding is fed, and water is splashed. 3 times a day, after the juvenile fish take the initiative to feed upstream, they will be fed powder directly, and then gradually converted to extruded feed in the later stage. The particle size will be adjusted in due course according to the size of the fish. Increase or decrease as appropriate. After 2 years of careful cultivation, both male and female light-lipped fish have reached sexual maturity, with a weight of 50-100g / tail.

[0018] On July 12, 2016, a female fish weighing 75-100 g and a male fis...

Abstract

The invention relates to a complete artificial propagation method for acrossocheilus fasciatus. The method comprises: acquiring wild acrossocheilus fasciatus juvenile fishes for acclimation, culturing until sex matured, using exogenous parturifacient chorionic gonadotropin (HCG), lutropin releasing hormone analog (LHRH-A3) and domperidone (DOM), through a one-time injection method, to promote sexual gland of parent fishes of acrossocheilus fasciatus which is mature naturally to develop further, through dry insemination to obtain oosperms, and through a special hatching equipment, performing flowing hatching until hatching. Rate of inducing spawning of parent fishes reaches up to 85%, and fertility rate reaches above 85%, and hatchability is above 70%. The method solves problems of large-scale production of acrossocheilus fasciatus fries.

Description

technical field [0001] The invention belongs to the technical field of fishery science application, and in particular relates to a method for artificial reproduction of fish. Background technique [0002] light lip fish ( Acrossocheilus fasciatus ), belonging to Cyprinidae ( Cypriniformes ) Cyprinidae ( Cyprinidae ) Barby subfamily ( Barbinae ) Lumiphorus ( Acrossocheilus ), is commonly known as "grouper" because the adult fish often inhabits between rock crevices and has 6 obvious black horizontal spots on the side of the body. It is mainly distributed in the mountainous rapids of Anhui, Fujian and Zhejiang. One of the main species of mountain economic fish. The smooth-lipped fish has tender meat and high DHA and EPA content, and is very popular among consumers. Due to habitat destruction, overfishing and other human activities, the wild resources of the smooth-lipped fish have dropped sharply, and the market price has risen. The large-scale production of seedling...
