在家鱼人工繁殖技术方面,近几年来,从普及到提高,在提高指导下普及,进展较快。初步总结了亲鱼的选择、运输和培育、催情剂的使用、注射的剂量和方式、生态条件的控制等主要技术环节。特别是我国西南和西北的高寒地区,由于亲鱼体内脂肪积累过多,性腺发育迟缓,因此采用催产前定期流水刺激和延长二次注射的相距时间,并适当调整二次注射的剂量,从而提
Artificial propagation of domestic fish in terms of technology, in recent years, from popularity to improve, under the guidance of popularization, progress faster. The main technical aspects of the selection, transportation and cultivation of broodstock, the use of aphrodisiacs, the dosage and mode of injection, and the control of ecological conditions were summarized. Especially in the alpine regions of southwestern and northwestern China, due to excessive accumulation of fat in the broodstock and gonadal retardation, the time of secondary injection is prolonged by regular flow stimulation before stimulation and the dose of secondary injection is adjusted appropriately
