Multidecadal Management Ensures High Sustainability and Low Risk in a Global Shark Biodiversity HotspotNARA Subscribed
Overfishing continues to drive the decline of sharks and rays worldwide, contributing to the deterioration of their global conservation status. Effective fisheries management can prevent overfishing, but only a small fraction of the global catch of sharks and rays has been assessed as being sustainable. A weight‐of‐evidence stock assessment framework, incorporating many stock‐specific analyses, is used herein to provide scient...
The use of size‐selective fishing gear has been fundamental for the successful management of shark populations. For the main Australian shark fisheries, available data sets on gillnet selectivity experiments conducted since the 1990s were used to estimate gillnet selectivity parameters for nine commonly caught non‐target species: broadnose, draughtboard, Port Jackson and school sharks, common and southern sawsharks, smooth ham...
Many anadromous (and semi‐anadromous) fish species, which migrate from marine to freshwater ecosystems to spawn and to complete their life cycle, are currently threatened by habitat degradation in the upper parts of estuaries and rivers, where spawning and juvenile nursery areas occur. This situation pertains to Nematalosa vlaminghi , a semi‐anadromous gizzard shad (Clupeidae: Dorosomatinae) endemic to south‐western Australia....
