Abstract

The sandbar shark (Carchrarhinus plumbeus) is a commercially important shark species to fisheries around the world but is known to be highly susceptible to over·fishing. During the late 1990s, changes in the targeting practices of Western Australian demersal gillnet fishing vessels, and an expansion of targeted demersal longlining in the north of the State, caused a rapid escalation in C. plumbeus catches. This study therefore aimed to collect the biological and fishery data necessary to assess the impacts of increasing exploitation of the species and to develop biologically appropriate techniques for assessing the sustainability of these fishery developments.
