西北太平洋柔鱼渔场分布与海面高度关系的初步研究
Study on the Relationship Between Distribution of Fishing Grounds for Ommastrephes bartramii and Sea Surface Height in the Northwest Pacific Ocean
摘要
Abstract
Ommastrephes bartramii is one of the most important commercial species in the morthwest Pacific Ocean, and is also the fishing target for Chinese squid jigging fleets. By comparing the relationship between different yield distribution of Ommastrephes bartramii and sea surface height anomaly (SSHA) during the migratory process, the main fishing ground can be forecast based on the data of sea surface height. On the basis of fishing data of Chinese fleets from July to November in 2012, the migration rules of fishing ground can be obtained by using every week’s catch gravity. The result indicates that the main yield is distributed where the value SSHA is more than 0 from 1th to 7th weeks, the main yield is distributed where the value of SSHA is more than 0 and less than 0 from 8th to 11th weeks, the main catch is distributed in the areas with SSHA < 0 from 12th to 14th weeks, and the main yield is also distributed in the fishing ground with SSHA > 0 during 15th to 19th weeks. The obviously difference of temporal and spatial distribution of squid resources in SSHA is related to violent activities of ocean front in the Kuroshio Extension Region.关键词
