Analysis of stock status and related indicators for key shark species of the Western Central Pacific Fisheries Commission
In this report we present, for seven of the fourteen key shark species, information on the geographicrange of catches; temporal trends in catch composition and catch rates; and key biological indicatorsof fishing pressure such as mean size and sex ratio. Whale sharks are assessed separately due toth...
