最近几个世纪以来,以全球气温升高为主要特征的全球气候变化对海洋渔业可持续发展的影响日益受到重视.金枪鱼渔业在全球远洋渔业中占据着重要的地位,而在金枪鱼渔业中,2005年以来鲣鱼年捕捞量已超过金枪鱼总捕捞量的一半以上.当前,在全球气候变化背景下,对未来鲣鱼渔业的响应和预测还处于起步阶段.为此,本文从鲣鱼捕捞历史变化、国内外研究现状与模型发展以及未来研究方向展望等三个方面描述了全球气候变化背景下的鲣鱼渔业,以期能够为鲣鱼渔业的可持续发展与研究提供一定的思路与想法.
Over the past several decades, impacts of climate changes on the sustainable development of marine fisheries have been greatly concerned, especially the global warming. Tuna fisheries play a significant role in marine fisheries not only due to their high economic values, but also because of their abundant captures. In tuna fisheries, catches of skipjack tuna (Katsuwonus pelamis) had accounted for more than half of the total captures since 2005. However, studies on responses of skipjack tuna to climate change are still on the very beginning cun:ently. Therefore, the paper reviewed the trend in captures of skipjack tuna over the past six decades, and compared the study histories on skipjack tuna under climate change between Chinese scientists and international scientists. Moreover, based on our current research status, we proposed our perspectives on the future concentrations on skipjack tuna.
