摘要：研究了刀鲚溯河生殖洄游规律、性腺发育过程，以及刀鲚繁殖季节洄游到各江段的水温变化、光照周期与强度、渗透压变化、水流强度、生物饵料等环境状况，模拟建立了专门的刀鲚亲本现代化培育池，通过人为调控、模拟刀鲚生殖洄游规律，促使刀鲚亲本生理发育成熟，解决了刀鲚从体成熟到性成熟的技术难题，实现了人工培育刀鲚亲本技术的突破。2012年3月29日—4月8日催产了4批刀鲚亲本，每批均产卵受精，受精率达70%以上，受精率最高达80.2%，平均每条雌鱼得苗2.1万尾。

Abstract: After eight years systematic studies, the Zhongyang Group detected the rules of Coilia nasus anadromous reproductive migration, gonadal development and collected the data of water temperature, photoperiod, osmotic pressure, flow intensity and live-prey during the Coilia nasus migratory breeding season. According to the bionic principles, the Zhongyang Group built the modern breeding ponds, promoted fish sexual maturation through regulation and achieve artificial propagation of Coilia nasus. From Mar. 29 to Apr. 8, 2012, four batches bloodstocks were artificial spawned and each batch were successfully fertilized. All the fertilization rates were more than 70% and the highest number of fertilization rate was 80.2%. Average 21 thousand larvae were hatched out from each female.

Key words: Coilia nasus; bloodstock breeding; gonadal development
