Download or read book A Preliminary Evaluation of the Status of Shark Species written by José Ignacio Castro and published by Food & Agriculture Org.. This book was released on 1999 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Chondrichthyes are a group of cartilaginous fish, where we have sharks, rays, and chimeras as members. This group plays an important role in aquatic ecology, as they act as predators throughout the food chain (e.g., sharks). However, many populations of Chondrichthyes are threatened by several factors (increased direct fishing, high mortality rate as accompanying fauna, marine pollution, habitat destruction, etc.). These declines are evident in many parts of the world and have come to the attention of scientists, conservation organizations, the media, and the general public. Fisheries legislation regulating international fisheries markets has been amended to provide greater protection for this group along with other species of fish. However, little is known about these species, which reinforces the importance of studies in order to have a better understanding of the elasmobranch stocks, as well as to identify the influences of the anthropic action of fishing. In response to knowledge on the low sustainability of cartilaginous fish fisheries on a global scale, FAO has developed an international plan of action for the management and conservation of these fish, with the aim of developing and implementing national plans of action to ensure management and conservation of these stocks, having as main recommendation the collection of information about the Chondrichthyes, especially the sharks. Even so, this group is little known in terms of biodiversity, ecology, behavior, and a host of other characteristics relevant to this taxon, which is very worrying. Chondrichthyes - Multidisciplinary Approach attempts to portray to the readers up-to-date information on Chondrichthyes to promote an overview of the current taxon, serving as an indispensable source of access to more accurate and detailed information on shark rays and chimeras.

Book excerpt: In The Empty Ocean, acclaimed author and artist Richard Ellis tells the story of our continued plunder of life in the sea and weighs the chances for its recovery. Through fascinating portraits of a wide array of creatures, he introduces us to the many forms of sea life that humans have fished, hunted, and collected over the centuries, from charismatic whales and dolphins to the lowly menhaden, from sea turtles to cod, tuna, and coral. Rich in history, anecdote, and surprising fact, Richard Ellis’s descriptions bring to life the natural history of the various species, the threats they face, and the losses they have suffered. Killing has occurred on a truly stunning scale, with extinction all too often the result, leaving a once-teeming ocean greatly depleted. But the author also finds instances of hope and resilience, of species that have begun to make remarkable comebacks when given the opportunity. Written with passion and grace, and illustrated with Richard Ellis’s own drawings, The Empty Ocean brings to a wide audience a compelling view of the damage we have caused to life in the sea and what we can do about it.

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.
Download or read book The State of World Highly Migratory Straddling and Other High Seas Fishery Resources and Associated Species written by Jean-Jacques Maguire and published by Food & Agriculture Org.. This book was released on 2006 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries for highly migratory species are important in all oceans and semi-enclosed seas, except for polar regions. Fisheries for straddling fish stocks are much more localised, primarily occurring in a few regions where continental shelves extend beyond the 200 miles Exclusive Economic Zone (EEZ), while most fisheries for other high seas fishery resources are deep-water fisheries. This publication examines issues relating to the stocks of these resources, including information on their state of exploitation. Findings include that about 30 percent of the stocks of highly migratory tuna and tuna-like species, more than half of highly migratory oceanic sharks and nearly two-thirds of the straddling stocks and the stocks of other high seas fishery resources are overexploited or depleted. Although the stocks concerned represent only a small fraction of the world fishery resources, they are key indicators of the state of an overwhelming part of the ocean ecosystem which appears to be more overexploited than EEZs.
