基于气候和环境因子的近海鲐鱼资源评估
Stock Assessment of Chub Mackerel (Scomber japonicus) Based on Environmental and Climatic Factors
摘要
Abstract
[Objectives] To study the effect of environmental and climatic factors on the growth,reproduction and recruitment of chub mackerel (Scomber japonicus).[Method] According to the catch and fishing effort of the purse seine fishery with lights (PSFL),the authors have developed a surplus production model and tried to optimize the model by using monthly sea surface temperature (SST) at 127°30′E and 29°30′N of the spawning ground in June from 2000 to 2011,sea surface temperature anomaly (Nino-SSTA) of Nino 3.4 area,Pacific decadal oscillation (PDO) index and southern oscillation index (SOI) from 1990-2011.The impacts of SST,Nino-SSTA,PDO and SOI on the chub mackerel stock and its maximum sustainable yield were analyzed.[Result] According to the Pearson correlation analysis,the authors observed that there was no correlation between PDO and the residual CPUE (Catch Per Unit Effort),but the relationships between SST,Nino-SSTA,SOI and the residual CPUE were significant.The optimized models by using the most correlated two factors,i.e.SST and SSTA,were better than that with non-environmental factors.[Conclusion] Therefore,it is concluded that the SST at 127°30′E and 29°30rN of the spawning ground in June,and Nino-SSTA have greatly affected the stock resources of Chub mackerel.It is also suggested that we should consider the environmental factors of each year in developing management strategies.关键词
