动物福利评估技术试图考虑到特定的需要和动物的问题。提供丰富（在居住环境中添加物理对象或同类）通常是一种让圈养动物有机会选择与谁或与什么互动以及如何度过时间的方式。然而，在圈养中经常被忽视的水生环境的一个基本组成部分是动物选择从事体育锻炼的能力。对于包括鱼类在内的许多动物来说，运动是其生命史的一个重要方面，并且已知具有许多健康益处，包括大脑和行为的积极变化。在这里，我们提出了一种方法来评估圈养动物的栖息地偏好。该协议可以很容易地适应于查看各种环境因素（例如，砾石与沙子作为基质，塑料植物与活植物，低流量与高流量的水）在不同的水生物种中，或与陆生物种一起使用。偏好的统计评估是使用雅各布的偏好指数进行的，该指数将栖息地从-1（避免）到+1（最喜欢）进行排名。有了这些信息，就可以从福利的角度确定动物想要什么，包括它们的首选位置。
Animal welfare assessment techniques try to take into consideration the specific needs and wants of the animal in question. Providing enrichment (the addition of physical objects or conspecifics in the housing environment) is often a way to give captive animals the opportunity to choose who or what they interact with and how they spend their time. A fundamental component of the aquatic environment that is often overlooked in captivity, however, is the ability for the animal to choose to engage in physical exercise. For many animals, including fish, exercise is an important aspect of their life history, and is known to have many health benefits, including positive changes in the brain and behavior. Here we present a method for assessing habitat preferences in captive animals. The protocol could easily be adapted to look at a variety of environmental factors (e.g., gravel versus sand as a substrate, plastic plants versus live plants, low flow versus high flow of water) in different aquatic species, or for use with terrestrial species. Statistical assessment of preference is carried out using Jacob's preference index, which ranks the habitats from -1 (avoidance) to +1 (most preferred). With this information, it can be determined what the animal wants from a welfare perspective, including their preferred location.
