Hatchery Trout Predation Data, Arizona
December 17, 2018
These data were compiled to evaluate the potential adverse impacts that stocked trout may have on native fish populaitons through predation. Hatchery-reared rainbow and brown trout are typically fed exclusively on commercially prepared pelleted feeds and have no experience catching or consuming life fish at the time of stocking and yet stocked fish are percieved to present a high predation risk for juvenile native fishes. These data were compiled to allow for a relative comparison of predation effectiveness between hatchery-reared fish and wild fish. Mean numbers of prey fish surviving in replicated overnight laboratory predation trials were quantified.

Are hatchery-reared Rainbow Trout and Brown Trout effective predators on juvenile native fish?
Hatchery‐reared Rainbow Trout Oncorhynchus mykiss and Brown Trout Salmo trutta are typically fed exclusively on commercially prepared pelleted feeds and have no experience catching or consuming live fish at the time of stocking. Despite this lack of predation experience, it is commonly assumed that stocked Rainbow Trout and Brown Trout will adversely impact native fish populations by...
