Humans are a constant in the lives of captive animals, but the effects of human-animal interactions vary. Research on the welfare impacts of human-animal interactions focus predominantly on mammals, whereas fish have been overlooked. To address this lack of research, we assessed the impacts of aquarium visitors on the behaviors of ten members of four elasmobranch species: an Atlantic stingray (), four southern stingrays (), two blue-spotted maskrays (), and three fiddler rays (). The rays engaged in a significantly higher proportion of active behaviors and a lower proportion of inactive behaviors when visitor density levels were high; however, there were no significant changes for negative or social behaviors. Individual analyses indicated that all three fiddler rays and one of the southern stingrays' active behaviors differed across visitor density levels, whereas there was no association between active behavior and visitor density levels for the other rays. Further research is needed to determine whether this pattern is an adaptive or maladaptive response to visitors, but this research provides much needed initial data on activity budgets within elasmobranch species.
人类在圈养动物的生活中是一个常量，但人兽互动的影响各不相同。关于人兽互动对福利影响的研究主要集中在哺乳动物上，而鱼类则被忽视了。为了解决这一研究不足的问题，我们评估了水族馆游客对四种软骨鱼类的十只个体行为的影响：一只大西洋黄貂鱼、四只南方黄貂鱼、两只蓝斑条尾魟和三只琴魟。当游客密度较高时，这些魟鱼表现出活跃行为的比例显著更高，不活跃行为的比例更低；然而，负面行为或社交行为没有显著变化。个体分析表明，所有三只琴魟以及其中一只南方黄貂鱼的活跃行为在不同游客密度水平下存在差异，而其他魟鱼的活跃行为与游客密度水平之间没有关联。需要进一步研究来确定这种模式是对游客的适应性还是适应不良的反应，但这项研究提供了软骨鱼类活动预算急需的初步数据。
