| Notes | Foraging fish, especially fish that exhibit aggressive feeding behavior, are more likely to be caught by anglers. For this study, the authors suspected that fish that were caught by hook-and-line would be more vulnerable to fishing and less likely to survive to reproduce than fish caught in fish traps. In this paper, the authors report that they found some evidence to support their hypothesis that vulnerability to angling is heritable. More importantly, “our data unexpectedly revealed that steelhead collected with in-river traps produced nearly twice as many adult offspring as steelhead collected by anglers” (from the Abstract). They recommend that hatcheries prefer to spawn fish collected by traps, rather than fish collected by anglers. Note: the results of this study came from only one generation of descendants. More research is needed |
