| 摘 要： | 可捕量的制订方法国内外无统一的标准。本文根据带鱼亲体和补充量关系，以留足每年夏汛的亲体数量、确保正常繁殖并获得较大补充量为前提，探讨东海带鱼可捕量的制订方法。分别给出了在资源正常年份夏、冬汛带鱼捕捞死亡系数和可捕量、资源量的关系，并用开发种群可捕量估算方法计算了年可捕系数。

| Abstract: | There is no unified method for calculating fishing-allowance nowadays.Based on relationship of spawning adults and recruitment fishes,this paperstudies a method for counting fishing-allowance of largehead hairtail in Eastchina Sea,for insuring the quantity of spawning adults in every summer ,tosufficingly reproduct larve fishes and get more recruitments.The paper dealswith a connection of fishing mortality,fishing-allowance and resource quantityin summer and winter fishing season in the resource balance year and givesallowance cofficient with allowance assesment method of exploided stock. |
