For centuries fishermen have conducted sustainable fisheries for sharks in coastal waters, and some still do. During recent decades an increase in effort and yield of shark catches, as well as an expansion of the areas fished has taken place. This leads to concern over the consequences for the populations of some shark species in several areas of the world's oceans. Sharks often have a close stock-recruitment relationship, long recovery times in response to over-fishing and complex spatial structures. Conservation and management of sharks is impaired by the lack of accurate data on catch, effort, discards, and trade data, as well as limited information on the biological parameters of many species and their identification.
