在东太平洋,渔群回游在两个热带及赤道地区,南北两个温带是其界限,特别丰收的鱼种是:长鳍金枪鱼,兰鳍金枪鱼,黄鳍金枪鱼及鲣鱼。黄鳍金枪鱼及鲣鱼为热带种,是主要丰收的鱼种,从价值与产量上看,黄鳍金枪鱼是主要鱼种。长鳍金枪鱼是唯一具有奇特的白肉,具有最高价格,而兰鳍金枪鱼价值较差,但比金枪鱼鱼稍高些,是这四种鱼中产量最

In the eastern Pacific Ocean, fishing reefs travel in two tropical and equatorial areas. Two southern and northern temperate zones are the boundaries. Species particularly bred are albacore tuna, bluefin tuna, yellowfin tuna and anchovy. Yellowfin tuna and anchovy are tropical species and are the major breeders of the species. In terms of value and yield, yellowfin tuna is the dominant species. Albacore is the only peculiar white meat with the highest price, while the bluefin tuna is less valuable but slightly more tuna than the tuna, which is the most abundant of the four species
