Book Description
Sharks are only a small proportion of world recorded fish landings, but they are a versatile and valuable resource. They sustain important fisheries in several countries and are a cheap but valuable source of protein for coastal communities dependent on subsistence fisheries. Sharks are exploited for their meat, fins, teeth, cartilage, liver and other internal organs. This report details species used and methods of preparation for various purposes.

Book Description
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.

Book Description
This report, a joint project of the Center for Marine Conservation and TRAFFIC International, regarding existing international agreements that may promote the conservation of sharks. The report analyses several existing international fisheries regimes, and identifies gaps in the conservation of sharks. Gaps are of two general types - geographical and functional gaps. A comparison of the range of key species of sharks with the jurisdiction of existing fisheries management regimes reveals large gaps in some areas.

Book Description
Get submerged in the amazing world of sharks! Your expert host, award-winning marine biologist Dr. David Shiffman, will show you how—and why—we should protect these mysterious, misunderstood guardians of the ocean. Sharks are some of the most fascinating, most ecologically important, most threatened, and most misunderstood animals on Earth. More often feared than revered, their role as predators of the deep have earned them a reputation as a major threat to humans. But the truth is that sharks are not a danger to us—they're in danger from us. In Why Sharks Matter, marine conservation biologist Dr. David Shiffman explains why it's crucial that we overcome our misconceptions and rise above cinematic jump scares to embrace sharks as the imperiled and elegant ocean guardians they really are. Sharing his own fascinating experiences working with sharks, Shiffman tells us • why healthy shark populations are a must for supporting ocean ecosystems—and the coastal economies that depend on them • why we're in danger of losing many shark species forever • what scientists, conservationists, and readers can do to help save these iconic predators • why so much of what you've heard about sharks and how to save them is wrong Exploring the core tenets of shark conservation science and policy, Shiffman synthesizes decades of scientific research and policymaking, weaving it into a narrative full of humor and adventure. Touching on everything from Shark Week to shark fin soup, overfishing to marine sanctuaries, Shiffman reveals why sharks are in trouble, why we should care, and how we can save them. Perfect for shark enthusiasts, Why Sharks Matter is an approachable, informative guide to the world of shark conservation and the passionate, fascinating, brilliant people who work to understand and protect our oceans. This fun read will have you looking at sharks with a fresh perspective and an understanding that the survival of sharks is crucial to the survival of another apex predator—ourselves.
