大目金枪鱼是印度洋金枪鱼渔业的主要渔获鱼种之一，其渔获量仅次于黄鳍金枪鱼和鲤排在第三位。从８０年代以来，其年产量获得迅速增长（图１），是一个极有生产潜力的鱼种。有关金枪鱼的基础生物学研究，国内开展很少，国际上亦主要对大西洋和太平洋的黄鳍金枪鱼群体研究报道?
Big headed tuna is one of the major catch species in Indian Ocean tuna fisheries, ranking third only to Yellowfin tuna and common carp. Since the 1980s, its annual output has seen rapid growth (Figure 1) and is a species of fish with great potential for production. The basic biological research on tuna has few domestic studies and mainly reports on yellowfin tuna populations in the Atlantic and Pacific Ocean.
