东、黄海鲐鯵鱼渔场与海洋环境关系的研究

根据2000～2004年7～12月东、黄海鲐碜鱼生产统计以及表层温度和盐度数据，利用地理信息系统软件和数理统计方法，对鲐碜鱼产量分布及作业渔场与表层温度、盐度的关系进行分析。结果表明，鲐碜鱼高产（20000区域主要在122～125°E、26～28°N和123～125°E、32～38°N之间的海域。整个渔场的产量分布呈南部和北部高而中部低的态势。南北渔场汛期差异明显，南部渔场高产期集中在8～9月份，北部渔场高产期集中在10～11月份，且北部渔场高产期的产量比南部渔场高出22．7％。鲐碜鱼适温范围为9．5～29．5℃，最适范围为28．5～29．5℃；适盐范围为30．9～34．4，最适范围为32．8～34．2。经非参数统计K—S检验结果是可信的。

A study on the relationship between the chub mackerel and Japanese scad fishing ground and marine environment in the East China Sea and Yellow Sea

Analysis of correlation between catch distribution of chub mackerel Scomber japonicus and Japanese scad Decapterus maruadsi,and marine environment in the East China Sea and Yellow Sea was done by means of geographical information system and statistical methods,in order to understand the tempo-spatial distribution of chub mackerel and Japanese scad in relation to marine environment parameters such as sea surface temperature and salinity from July to November in 2000~2004.The results indicated that high yield...
