Abstract

Environmental enrichment is important for the long-term wellbeing of captive organisms and is an understudied topic in aquatic taxa, particularly ectothermic organisms such as elasmobranchs. This study examines how individual elasmobranchs use environmental enrichment objects before and after feeding. The species included were Heterodontus francisci (horn shark), Cephaloscyllium ventriosum (swell shark), Triakis semifasciata (leopard sharks) and Caliraja inornata (California skate). Results indicate that interaction peaks post-feeding with animals interacting with objects that have a different color relative to the surrounding environment. Interaction frequency is highest after feeding following an initial lag phase, particularly for T. semifasciata. These data suggest that environmental enrichment should take into account the optical range of elasmobranchs as well as timing of when enrichment objects are introduced to increase enrichment efficacy.

与富集物的相互作用取决于颜色，并且在喂食后增加，而在其他种类中没有

环境富集对于圈养生物的长期健康是重要的，并且是水生分类群中一个未充分研究的主题，特别是变温生物，如板鳃类。本研究考察了弹性鳃在进食前后如何利用环境富集物。包括角鲨（Heterodontus francisci）、角鲨（Cephaloscyllium ventriosum）、豹鲨（Triakis semiifasciata）和加利福尼亚鳐（Caliraja inornata）。结果表明，动物与周围环境颜色不同的物体相互作用时，喂食后相互作用达到峰值。经过最初的滞后期后，进食后的相互作用频率最高，尤其是半筋膜绦虫。这些数据表明，环境富集应考虑弹性枝的光学范围以及引入富集物的时机，以提高富集效果。

期刊介绍： This journal publishes relevant information on the behaviour of domesticated and utilized animals. Topics covered include: -Behaviour of farm, zoo and laboratory animals in relation to animal management and welfare -Behaviour of companion animals in relation to behavioural problems, for example, in relation to the training of dogs for different purposes, in relation to behavioural problems -Studies of the behaviour of wild animals when these studies are relevant from an applied perspective, for example in relation to wildlife management, pest management or nature conservation -Methodological studies within relevant fields The principal subjects are farm, companion and laboratory animals, including, of course, poultry. The journal also deals with the following animal subjects: -Those involved in any farming system, e.g. deer, rabbits and fur-bearing animals -Those in ANY form of confinement, e.g. zoos, safari parks and other forms of display -Feral animals, and any animal species which impinge on farming operations, e.g. as causes of loss or damage -Species used for hunting, recreation etc. may also be considered as acceptable subjects in some instances -Laboratory animals, if the material relates to their behavioural requirements
