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 then screened their ability swim along a channel while avoiding obstructions. The results show that even relatively short period enrichment improves O. agility.
