Abstract

To test whether swimming skills can be improved by exposure to structurally complex environments, juvenile rainbow trout Oncorhynchus mykiss were reared in either physically enriched or plain tanks for 2 months and were then screened to test their ability to swim along a channel while avoiding obstructions. The results show that even a relatively short exposure period to enrichment improves O. mykiss swimming agility. (C) 2016 The Fisheries Society of the British Isles
