摘  要：
水温是影响鲐鱼生长、繁殖、补充的重要因素之一。根据东、黄海鲐鱼灯光围网渔业渔获量、标准单位捕捞努力量渔获量(CPUE)和2月产卵场(127°30'E、29°30'N)平均海表面温度(SST),建立了基于SST因子的剩余产量模型,分析SST对东、黄海鲐鱼资源和持续产量的影响。研究表明:持续产量可由捕捞努力量和SST的函数来表征,表达式为:Yt=1 080.97ft-0.006ft2+114.51SSTt ft-2.91SSTt2ft,鲐鱼资源量和持续产量的变动受产卵场SST和捕捞努力量控制。分析认为,2月产卵场最适SST范围为18.5～20.6℃。为此,建议在渔业管理中应根据各年海洋环境状况来确定最大可持续产量,并实时调整管理方案。

摘  要：
Sea water temperature(SST) is one of the important factors that impact growth,reproduction and recruitment of chub mackerel.According to the catch and standardized CPUE data of purse seine fishery with lights(PSFL) and monthly sea surface temperature of the spawning ground in February from 1998 to 2006,the author developed a surplus production model for chub mackerel based on SST,and analyzed the impact of SST on the chub mackerel stock and its sustainable yield.The result indicates the relationship between sustainable yield and SST,can be expressed as Yt=1080.97ft-0.006t f 2+114.51SSTt ft-2.91SSTT2 ft.Variations of chub mackerel stock biomass and sustainable yield are controlled mainly by SST in the spawning ground and fishing effort.The optimal SST range for chub mackerel spawning is 18.5-20.6℃.It is suggested that the maximum sustainable yield may be estimated based on the annual different environmental conditions,and the fishery management measures should be adjusted in real-time.
