This up-to-date and comprehensive electronic book on CD-ROM provides a complete guide to sharks and the research and conservation efforts of the National Oceanic and Atmospheric Administration (NOAA) through the National Marine Fisheries Service (NMFS). Sharks are a valuable part of marine ecosystems and NOAA Fisheries is committed to conserving shark populations. Most sharks are vulnerable to overfishing because they are long-lived, take many years to mature, and only have a few young at a time. Recovery from overfishing can take years or decades for many shark species. Therefore, sharks need conservation and NOAA Fisheries is conducting research, implementing restrictions and working with fisherman domestically, and pursuing international conservation. These steps will ensure that those shark populations that are healthy remain so and those shark populations that are overfished recover. Shark Management - The Magnuson-Stevens Fishery Conservation and Management Act requires overfished shark stocks to be rebuilt and requires healthy shark populations to be maintained.Many shark stocks, particularly in the Atlantic, are overfished and must be rebuilt. Nationally, the United States recently enacted a ban on shark finning that prohibits any person under U.S. jurisdiction from engaging in shark finning and possessing shark fins harvested on board a U.S. fishing vessel without the corresponding carcasses. Finning is defined as the practice of removing the fin(s) from a shark and discarding the remainder of the shark at sea.The United States is a conservation leader internationally and was a key player in developing the Food and Agriculture Organization's International Plan of Action for the Conservation and Management of Sharks. Shark Science - In meeting its Congressional mandate under the Magnuson-Stevens Fishery Conservation and Management Act to rebuild shark! populations in the United States, NOAA Fisheries conducts shark research on a periodic basis to determine the abundance of shark species. The data collected by scientists in these research programs provide fishery managers with critical information they need to monitor shark populations and implement fishery regulations to maintain population levels. Shark Species - Common Human Encounters - Experts caution sea-goers to beware of sharks 6 feet or longer due to the damage they can cause to humans in a single bite. Among the species that grow to this size and have been known to attack humans are bull sharks, tiger sharks and great white sharks. However, these are not the predominant shark species that a person is likely to come across in the surf zone at the beach in the United States. In fact, about 90 percent of human-shark encounters are with smaller species of sharks not normally implicated in fatal attacks. One challenge in identifying sharks that attack humans is that people don’t always get a good look at the shark in the water. Even if they do, they usually do not know what kind of shark it was. Often, experts use the bite pattern to determine the responsible species and are sometimes able to extract teeth samples from the bite area, which helps identify the species.
