Conventional tagging of sharks in Western Australia: the main commercial species exhibit contrasting movement patterns
Understanding movement patterns underlies effective management and conservation measures. The current study summarises the main findings from a tagging program of Western Australian sharks to provide insights into the movement patterns of the main commercial shark species: dusky (Carcharhinus obscur...
