Abstract
AbstractVirtually no information is currently available regarding the relative effects of innate and experiential factors on the development of species identification in fish. Those studies which have approached the problem through schooling behavior have confounded species identification with attraction to a single available school of species‐mates. In this study, isolated Brachydanio rerio spent significantly less time in nonpolarized schools with species‐mates than controls when animals of a related species were available as an alternative. This difference suggests the involvement of experiential factors in species identification and questions the assumption that species identification is entirely innate.
