In 2007 the Shark Specialist Group convened an expert workshop with the aim of using the IUCN Red List Categories and Criteria to assess the conservation status of pelagic sharks and rays. This report provides a detailed summary of the IUCN Red List assessment for these species, highlighting species of conservation concern as well as identifying species assessed as Least Concern and Data Deficient.
Many shark populations are in serious decline worldwide with little shark fisheries management in place. The IUCN Shark Specialist Group has compiled a Global Status Report for Chondrichthyan Fishes (the Sharks, Rays and Chimaeras), with Red List assessments for over 100 species and regional reports on the status of shark fisheries, together with information on taxonomy; life history; trade; socio-economics; threats; and conservation and management initiatives.
Sharks and their relatives, the rays and chimaeras, are the diverse group of cartilaginous fishes that have evolved over 400 million years. Historically considered of low economic value to large-scale fisheries, today many of these fishes have become the target of directed commercial and recreational fisheries around the world, and they are increasingly taken in the by-catch of fisheries targeting other species.

This report analyses several existing international fisheries regimes, and identifies geographical and functional gaps in the conservation of sharks. A comparison of the range of key species of sharks with the jurisdiction of existing fisheries management regimes reveals large gaps in some areas.
Overview of the findings of regional TRAFFIC studies in Europe, India, East and Southern Africa, Southeast Asia, East Asia, Oceania and North and South America. It highlights the fisheries, shark products in trade, and the processing, preparation and use of these products in domestic and international markets. It also discusses the management and conservation implications.
