中文摘要：生物学参考点用来指导渔业管理决策,通常以捕捞死亡系数来表达。补充型过度捕捞常常被理解为一个种群被捕捞至补充量出现实质性减少或失败时才发生。该定义很含糊,不能建立生物学参考点,它与捕捞死亡系数挂钩。因此,提出从减少一个世代亲体量的捕捞压力水平出发,定义补充型过度捕捞即是捕捞死亡系数使产卵群体低于其亲代平均生物量的临界点。常规的模型和亲体补充量数据都可确定这一参考点,并与亲体量的更替联系起来,从而实现渔业资源的可持续发展。以印度洋黄鳍金枪鱼渔业为例,计算了其补充型过度捕捞的生物学参考点,提出限制围网诱鱼装置作业,减少幼鱼资源的过度开发,防止补充型过度捕捞发生引起资源的衰退。

外文摘要：Biologlcal reference points were used to guide fisheries management decisions. The reference points most often used were expressed in terms of fishing mortality rate. Recruitment overfishing was usually understood to occur when a population was fished down to a point where recruitment substantially reduced or fails. It was not used as a basis for a biological reference point because the definition was vague and could not be readily related to fishing mortality. The authous proposed an alternative definition of recruitment overfishing in terms of the level of fishing pressure that reducee the spawning biomass of a year class over its lifetime below the spawning biomass of its parents on average. Conventional models and types of data could be used to determine this level of fishing mortality,which clearly related to the replacement of spawning biomass and thus to sustainability of a population. It was suggested that limiting purse seining with fish attractive device could alleviate over - exploitation on young fish and prevent from recruitment overfishing that would result in resource depletion exemplified by yellowfin tuna fishery in the Indian Ocean.
