摘要
本文研究浙江近海1970年到1992年鲐鱼渔获量变化与Elnino现象的关系，结合捕捞强度，长江中下游汛期（4—9月）降水量距平年际变化综合分析，探讨浙江近海鲐鱼渔获量变动规律，为合理开发渔业资源提供科学依据。
Based on the fishing intensity the relationship between the EI-nino phenomenon, the variations of catch of scomber japonicus and Decapterus maruadsi, and the precipitatioon in the offshore waters of Zhejiang Province is analysed, the variation pattern of catch of scomober japonicus and decapterus mariuasdsi in this area is found, which provides valuable information for rational exploitation of the resources.
