Effects of simulated catch-and-release angling of Atlantic salmon shortly before spawning on the viability and development of their offspring
The principle of catch-and-release (C&R) angling is to conserve fish populations while allowing the socioeconomic benefits associated with recreational angling to continue, even at low-stock abundances. We explored how angling-associated parental stress close to spawning could influence early de...
