Northeast Pacific Shark Biology, Research and Conservation, Part B, Volume 78, the latest release in the Advances in Marine Biology series contains updated chapters that focus on a variety of topics, including, but not limited to, an Introduction to Northeast Pacific shark biology, ecology, and conservation, Shark Interactions with Directed and Incidental Fisheries in the Northeast Pacific Ocean: historic and current encounters and challenges for shark conservation, An Introduction to modeling abundance and demographic parameters in shark populations, and Sharks in Captivity: The Role of Husbandry, Breeding, Education and Citizen Science in Shark Conservation. Specialty areas in this longstanding series include marine science, both applied and basic, a wide range of topical areas from all areas of marine ecology, oceanography, fisheries management and molecular biology, and the full range of geographic areas from polar seas, to tropical coral reefs are included making this an ideal reference and resource for postgraduates and researchers in a variety of fields. - Reviews articles on the latest advances in marine biology - Authored by leading figures in their respective fields of study - Presents materials that are widely used by managers, students, and academic professionals in the marine sciences - Provides value to anyone studying bottlenose dolphins, deep-sea macrofauna, marine invertebrates, pinna nobilis and ecology, amongst other study areas
The status of shark species is reviewed based on the available data. A review of the history of shark fisheries demonstrates that intensive shark fisheries are not sustainable. Numerous problems are encountered in assessing shark populations: a general lack of biological and fishery data, lack of suitable models, and lack of validated age estimates. Sharks have an unusual combination of biological characteristics: slow growth and delayed maturation, long reproductive cycles, low fecundity and long life spans. These characteristics make them vulnerable to overfishing. A preliminary evaluation of the status of shark species is made on the basis of historical data, the reproductive potential of each species, and the level of exploitation of the species. In this document, exploited shark species are classified numerically according to their vulnerability. The majority of these species are listed as Category 1, indicating that there are not sufficient data to assess the species. Available data indicate that sharks are very vulnerable and are threatened by overexploitation in many parts of the world.
