Yellowfin tuna ( Thunnus albacares) is a major target species of the tuna purse seine fishery in the Eastern Pacific Ocean. 黄鳍金枪鱼是东太平洋金枪鱼围网渔业中的主要渔获种类之一。
Catch rate analysis of yellowfin tuna from longline fishery using generalized linear model in the Indian Ocean 利用广义线性模型分析印度洋黄鳍金枪鱼延绳钓渔获率
Based on the catch data of yellowfin tuna captured by Chinese tuna longline fleet in the west-central Indian Ocean from January to June in 2003 and 2004, the basic biological characteristics of catch composition of yellowfin tuna captured were investigated. 根据2003-2004年1-6月印度洋中西部海域金枪鱼延绳钓所捕获的黄鳍金枪鱼数据,对其基本的生物学特征进行了研究。
The catch weight was different in various sea areas, the proportion of skipjack tuna in the sea area east of 162 ° E was higher than that west of 162 ° E, while yellowfin tuna was contrary to skipjack tuna. 渔获物重量组成存在海域差异,在162°E以东海域鲣鱼比例高于以西海域,黄鳍金枪鱼则是在162°E以西海域的比例较高。
Longline fishery dominates the Tonga tuna fisheries. Albacore, yellowfin tuna, and bigeye tuna are the main catch species. 汤加金枪鱼渔业以延绳钓渔业为主,主要捕捞鱼种是长鳍、黄鳍和大目三种金枪鱼。
The results showed that the distribution of yellowfin tuna longline fishing-grounds are mainly located in the tropical areas, which are between 20 ° N and 20 ° S. 结果表明:太平洋延绳钓黄鳍金枪鱼渔场主要分布在20°N&20°S之间的热带太平洋海域,具纬向分布特征。
The barycenter of fishing ground for yellowfin tuna were different in El Nino and La Nina condition from the other year. 黄鳍金枪鱼各月的作业渔场重心与其他年份差异较大的年份几乎都在厄尔尼诺和拉尼娜发生的年份。
