Does catch and release affect the mating system and individual reproductive success of wild Atlantic salmon ( Salmo salar L.)?
Abstract In this study, we documented the breeding system of a wild population of A tlantic salmon ( S almo salar L .) by genetically sampling every returning adult and assessed the determinants of individual fitness. We then quantified the impacts of catch and release ( C & R ) on mating and re...
