Abstract

The study of swimming behavior is an important part of fish biology research and the swim tunnel is used to study swimming performance as well as metabolism of fish. In this investigation, we have developed a user-friendly, automated, modular, and low-cost swim tunnel that permits to study the performance of one or more fish separately, as well as a small group of individuals. To validate our swim tunnel, we assessed swimming activity of four different species (zebrafish, medaka, guppy, and cavefish) recording reliable data of swimming behavior and performance. Because swimming behavior has been recently used in different fields from physiology to ecotoxicology, our setup could help researchers with a low-cost solution.
