Fish ‘personality’ linked to vulnerability to angling

28 octubre 2014

Individual differences in moving activity in a novel environment are linked to individual differences in vulnerability to angling, according to an experimental study. The study used novel, long-term observations of individual behavior in groups and authentic angling trials to analyze if behaviors predict the vulnerability to fishing in brown trout reared in traditional and enriched hatchery rearing environments. Based on the results, it can be predicted that fishing modifies the heritable behavioral traits of fish by favoring cautious fish.
