摘要
海洋渔业与气候密切相关 ,因为渔业捕捞不管是在近海还是在大洋中 ,都要受到天气变化的影响 :浓雾的产生容易使渔船迷航导致触礁 ;大风的突袭 ,会造成生命财产重大损失。而且天气的变化对鱼群洄游路线、鱼群的集散分布、渔汛的迟早、渔场位置的迁移 ,都有直接或间接的影响。本文分析了气候各要素 (气温、风、气压、降水、光照等 )的变化对渔场、渔汛以及海洋捕捞作业的影响 ,为科学捕捞和安全生产提供一些借鉴。
The Marine fisheries prodution has a consanguineous connetion with climate,because the catching work falls under the influence of weather change in spite of in offing or in ocean.For instance: tick fog being makes fishers get lost easily,down to knocking on the rocks.The bluster swooping usually lead to life and possession damnify loss.And that the change of weather effects straightly or indirectly shoal's moved-path ,shoal collection and scatter,shoal distibution,the firstor or late of the fish-flood,and the movement of fishing ground position.This article analyse what influence the change of climate factor(air temperature、wind、air pressure、 precipitation and illurnination and so on)process with fishing ground、fish-flood and the ocean catching work,So that offers some use for reference for scientific catching and secure production.
