An estimated 5.66 x 10(7) fish (summed quarterly 95% confidence intervals: 3.01 x 10(7)-1.07 x 10(8)) weighing 258.4 t (143.2-467.9 t) were killed on the cooling-water intake screens of the 2400 MW Longannet Power Station (Forth estuary) in January 1999--December 2000. Abundance and number of species (40) collected were close to predictions for a power station of this size and latitude. Potential losses of equivalent adult whiting (Merlangius merlangus), cod (Gadus morhua), and plaice (Pleuronectes platessa) through deaths of juveniles were estimated at 353.1 t (208.0-603.2 t) worth approximately euro 429,266 (euro 246,592-752,765) in 1999--2000. Fish catch-per-trawl in the estuary was generally not noticeably greater during a year of low water withdrawal (coal miners' strike of 1984--1985) when compared to other years from 1982 to 2001, except for gobies (Pomatoschistus spp.). A fish-return system is being tested at Longannet to reduce mortality.
据估计，1999年1月至2000年12月期间，位于福斯湾的2400兆瓦朗甘尼特电站的冷却水取水口滤网共杀死了约5.66×10⁷条鱼（按季度汇总的95%置信区间：3.01×10⁷ - 1.07×10⁸），这些鱼重258.4吨（143.2 - 467.9吨）。所收集的鱼类数量和种类（40种）接近对这种规模和纬度的电站的预测。1999 - 2000年，因幼鱼死亡导致的成年欧洲无须鳕、鳕鱼和鲽鱼的潜在损失估计为353.1吨（208.0 - 603.2吨），价值约429,266欧元（246,592 - 752,765欧元）。与1982年至2001年的其他年份相比，在低取水量年份（1984 - 1985年煤矿工人罢工），河口的每次拖网捕鱼量通常没有明显增加，除了虾虎鱼（Pomatoschistus spp.）。朗甘尼特电站正在测试一种鱼类回流系统以降低死亡率。
