A Meta-Analysis of Hooking Mortality of Nonanadromous Trout

Abstract.—The results of 18 studies of hooking mortality of nonanadromous trout were integrated with meta-analysis. Studies were coded for all variables suspected of having a relationship to rates of hooking mortality. The analysis showed that trout caught on bait died at higher rates than trout caught on artificial flies or lures, that fish caught on barbed hooks had higher mortality rates than fish caught on barbless hooks, that brown trout Salmo trutta had lower mortality rates than other species of nonanadromous trout, and that wild trout died at higher rates than hatchery-reared trout. Other variables, including size of hooks, number of hooks, and water temperature, did not show a statistically significant relationship to hooking mortality. The results of this review should assist fisheries management agencies in refining and developing policies regarding fisheries regulations.
