北太平洋长鳍金枪鱼延绳钓渔场分布及其与海水表层温度的关系
Relationship of distribution of albacore Thunnus alalunga longline fishery grounds and sea surface temperature in the North Pacific Ocean
摘要
Abstract
The albacore Thunnus alalunga longline fishery is one of the important fisheries in the Pacific Ocean. According to the collected catch data of the albacore, sea surface temperature (SST) derived from satellite 3-level production and literatures, the distribution of albacore longline fishery grounds and its relationship with SST were analyzed quantitatively or qualitatively by using GIS technology. The results showed that the distribution of longline albacore fishing-grounds was latitudinal zones, and mainly located in the area of 25~40°N. The average SST and median SST of albacore longline fishing-grounds were 23. 6°C and 24. 5°C respectively. In addition, average SST of most fishing grounds was 16 - 28°C. The distribution curve of SST was a negative skew and the distribution curve of catch was a positive skew. Variation of the average CPUE and the average yields were similar and they were the highest when the SST wasbetween 18~20°C. The catch of fishing is different at lower SST area (16~23°C) and higher SST area (24~27°C) , but mainly distributed at lower SST area (16~23°C). There was a correlation between CPUE of albacore and PDO index by time series analysis.关键词
