In Canada, the Fisheries Act requires all water takers to avoid, mitigate and offset fish losses. To satisfy the act’s requirements, operators of power plants are required to undertake habitat restoration projects to compensate for fish impinged and entrained at cooling water intake structures. Scaling the quantity of restoration needed, and measuring whether adequate compensation has been achieved, requires a metric that expresses the losses and gains in comparable units. Development of such a metric is especially difficult in the case of power plants, because the losses often consist of a mix of species and life stages that are very different from those produced by technically feasible restoration projects. This paper documents the method that has been developed for quantifying offsets for impingement and entrainment at the Bruce Generating Stations on the eastern shore of Lake Huron, and demonstrates how the method is being used to estimate the offset to be provided by removal of a dam on the nearby Saugeen River.

量化加拿大核电厂的修复补偿

在加拿大,渔业法要求所有取水者避免、减轻和抵消鱼类损失。为了满足该法案的要求,发电厂的运营商必须进行栖息地恢复项目,以补偿在冷却水进水结构中受到撞击和夹带的鱼类。衡量所需恢复的数量并衡量是否获得了足够的补偿,需要一个以可比单位表示损失和收益的指标。在发电厂的情况下,制定这样的指标尤其困难,因为损失通常由物种和生命阶段的混合组成,这与技术上可行的恢复项目产生的损失非常不同。
