苏格兰考察船自1925年1月以来的拖网数据显示，温暖水域中上层物种--凤尾鱼(Engraulis Encrasicholus)和沙丁鱼(Sardina Charchardus)的渔获量在1995年后突然增加。大多数是在每年的第一季度观察到的，1998年和2003年的数字最多，尽管很少有最后一个季度的数据。作者认为，这些长期变化与海洋温度上升有关，尽管确切的原因尚不清楚。
Trawl data from Scottish research vessels dating from January 1925 show that catches of the warm water pelagic species, anchovy (Engraulis encrasicholus) and sardine (Sardina pilchardus), increased suddenly after 1995. Most were observed in the first quarter of each year, with 1998 and 2003 having the largest numbers, although few data are available for the last quarter. The authors believe that these long-term changes are related to rising sea temperatures although the exact causal mechanism is not clear.
