摘要(Abstract):
【目的】研究环境与气候因子对鲐鱼的生长、繁殖和补充的影响。【方法】根据我国东、黄海鲐鱼灯光围网渔业捕获量、捕捞努力量建立剩余产量模型,尝试用6月产卵场(127°30′E、29°30′N)的平均海表温(SST)、Nino 3.4区海表温度距平值(Nino-SSTA)、太平洋中高纬年代际振荡(PDO)和南方涛动指数(SOI)4个因子对剩余产量模型进行优化,分析SST、Nino-SSTA、PDO和SOI对东、黄海鲐鱼资源量和最大可持续产量的影响。【结果】经过Pearson相关性分析,发现PDO对CPUE残差无影响,对SST、Nino-SSTA和SOI有影响。选取相关性较高的SST、Nino-SSTA对模型进行优化,发现优化后的模型对鲐鱼渔获量的拟合效果比优化前显著增强。【结论】6月份产卵场SST、Nino 3.4区海表温度距平值对鲐鱼资源变化有明显的影响,建议在渔业管理中应根据各年环境因子的情况确定最大可持续产量,合理制定管理策略。
