潮汐能开发的进展表明，未来许多水流湍急的沿海海峡和弯道将配备流中涡轮机。考虑到涡轮机设计的多样性，可以合理地假设将使用大转子和小转子。每种设计都意味着不同的方式来干扰当地环境。然而，有很少的现有报告中的鱼类行为在流涡轮机的存在。本文研究了鱼类游动行为与不同潮汐涡轮机转子碰撞风险的关系。基于现有的模型和蒙特-卡罗模拟与生物数据从现场调查的刀片罢工概率计算为三个不同的和广泛的鱼类类群（豆娘鱼，安魂鲨，梭鱼）。结果表明，小型涡轮机具有较高的风险，只要鱼被认为不会发现并积极避免转子。然而，下面的论文指出，对模型的改进可能会改变这些结果。此外，它表明，潮汐涡轮机的潜在危害在不同的鱼类类群和个体之间存在很大差异。似乎是“坏”的人最有理由害怕。
Advances in tidal power development indicate that many coastal straits and bends with rapid currents will be equipped with in-stream turbines in the future. Considering the variety among turbine designs it is reasonable to assume both large and small rotors will be utilized. Each design implies a different way of interfering with local environment. However, there are very few available reports on fish behaviour in the presence of in-stream turbines. In this paper fish swimming behaviour is investigated in relation to the risk of colliding with different tidal turbine rotors. Based on an existing model and Monte-Carlo simulations with biological data from a field survey the blade-strike probability is calculated for three different and widespread fish taxa (damselfishes, requiem sharks, and barracudas). The results indicate that small turbines carry higher risks, as long as fish are assumed not to detect and actively avoid the rotor. However, the following paper indicates that improvements to the model may alter these results. Furthermore, it is shown that the potential hazard of tidal turbines varies strongly between different fish taxa and individuals. And seemingly it is ‘the bad’ that has the most reasons to be afraid.
