Cage diving to view great white sharks and other iconic marine mega-fauna is a huge part of the marine wildlife tourism industry. But cage diving is considered a double-edged sword. On one hand, it fosters positive conservation ethics in tourists and raises awareness. However, on the other hand, there are concerns about animal welfare, costs to shark fitness and disruption of the natural ecology of habitats, mostly related to the use of bait to attract sharks. In fact, at cage-diving sites that use bait, Lauren Meyer and her colleagues determined that the swimming behaviour and daily activity levels of great white sharks are affected but not their nutrition. However, Meyer et al. (2019) have just investigated the impact on the other fishes, including rays that are unintentionally fed at these sites, and it turns out, those fishes do experience the effects.

看不到大白鲨吗？为它诱饵。

笼子潜水以观赏大白鲨和其他标志性的海洋大型动物，是海洋野生动物旅游业的重要组成部分。但是笼子跳水被认为是一把双刃剑。一方面，它在游客中树立了积极的保护道德观，并提高了人们的意识。但是，另一方面，人们对动物福利，鲨鱼适应成本和栖息地自然生态的破坏存在担忧，这主要与使用诱饵吸引鲨鱼有关。实际上，在使用诱饵的网箱潜水场所，劳伦·迈耶（Lauren Meyer）和她的同事们确定大白鲨的游泳行为和日常活动水平受到影响，但其营养并未受到影响。然而，迈耶等。（2019）刚刚调查了对其他鱼类的影响，包括在这些地点无意喂食的射线，结果是，
