Prevalence and Implications of “Must‐Kill” Angling Regulations for the Management of Invasive Fishes

Fisheries Management and Ecology, EarlyView.
ABSTRACT Freshwater biodiversity is increasingly threatened by invasive species, which can disrupt native fish populations and the fisheries they support. Must‐kill regulations, which prohibit the live release of invasive fish caught by recreational anglers, are a management strategy that can be implemented to limit the negative effects of invasive ...
