#Environmental_enrichment is the modification of typically barren hatchery rearing tanks to simulate natural habitats or make more complex rearing environments. Vertically-suspended environmental enrichment has been shown to improve the growth and hatchery rearing efficiencies for numerous salmonid species. This experiment documents the effects of water velocities in #circular_tanks larger in diameter than 1.8-m, with and without the presence of fish, and with and without the presence of a novel vertically-suspended environmental enrichment structure. The findings demonstrate that a unique form of environmental enrichment and two distinct #fish_densities can act alone and also interact to dramatically alter within tank water #velocity profiles.
