鲥鱼是长江下游的名贵经济鱼类之一。每年4—5月由海入江上溯产卵,形成了一年一度的渔汛期。了解鲥鱼生殖腺发育的特点及怀卵量的变化,掌握其生殖腺成熟时撞、繁埴地点以及繁殖的生态条件等,为长江鲥龟资源增殖提供可靠的生物学依据。将收集到的生殖腺材料进行整理。由于条件的限制,鲥鱼在海洋里的生殖腺标本,采集到的较少,有待今后补充。鲥鱼入江后的精巢发育不像卵巢那样复杂,在此不详加
Anchovy is one of the rare economic fish in the lower reaches of the Yangtze River. April to May each year by the sea into the river spawning, forming an annual fishing season. To understand the characteristics of gonad development and the changes of fecundity, and grasp the impact of bursting, breeding sites and reproductive ecological conditions of mature gonads, so as to provide a reliable biological basis for the proliferation of marsh turtle resources. The collected gonad material is sorted out. Due to conditions, catfish in the sea gonads specimens, collected less, to be added in the future. Catfish into the river after the development of the testis is not as complicated as the ovary, this is unknown plus
