Book Sharks  An Eponym Dictionary

Download or read book Sharks An Eponym Dictionary written by Michael Watkins and published by Pelagic Publishing Ltd. This book was released on 2015-01-30 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fascinating reference book delves into the origins of the vernacular and scientific names of sharks, rays, skates and chimeras. Each entry offers a concise biography, revealing the hidden stories and facts behind each species’ name. Full of interesting facts and humorous titbits, the authors’ extensive research and detective work has made this book a comprehensive source of knowledge on everyone associated with the naming of a species. A fascinating resource for anyone with an interest in sharks, from curious naturalist to professional ichthyologist, it is an essential addition to the library of anyone wishing to satisfy those tickling questions on the mysteries behind the names. Sometimes a name refers not to a person but to a fictional character or mythological figure. Eptatretus eos is named after the Greek goddess of the dawn in reference to the pink colouring of the hagfish. The Chilean Roundray Urotrygon cimar, named after Centro de Investigación en Ciencias del Mar y Limnología in honour of its 20th anniversary, and the Angular Angelshark Squatina Guggenheim, named after the John Simon Guggenheim Memorial Foundation, are both named after institutions. The Whiteleg Skate Amblyraja taaf is just a shorthand way of describing a toponym – Territoire des Terres australes et antarctiques françaises. There are also entries which are light-hearted such as the one for a lady who told us "that decoration of her cakes have included roughtail skate Bathyraja trachura, red abalone Haliotis rufescens, and chinook salmon Oncorhynchus tshawytscha." Following the success of their previous Eponym Dictionaries, the authors have joined forces to give the Elasmobranch group of fishes a similar treatment but they have also included the describers and authors of the original descriptions of the fishes involved, in addition to those names that are, or appear to be, eponyms. They have tracked down some 850 names of living as well as dead people. Of these half are eponyms after people who have fish named after them and may also have described a fish or fishes. The other half are ichthyologists, marine biologists and other scientists who have become involved in the description and naming of sharks, rays, skates and chimeras. For each person mentioned there is brief, pithy biography. Additionally there are some 50 entries for what sound like eponyms but turned out not to have any connection to a person, such as the Alexandrine Torpedo is named after the city in Egypt and not Alexander the Great. In some cases these are a reminder of the courage of scientists whose dedicated research in remote locations exposed them to disease and even violent death. The eponym ensures that their memory will survive, aided by reference works such as this highly readable dictionary. Altogether 1,577 fishes are listed.

Ebert and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This fully illustrated guide is designed to assist with the identification of a selection of deep-sea cartilaginous fishes of the Southeastern Atlantic Ocean and that portion of Southwestern Indian Ocean from 18°42'E to 30°00'E (FAO Fishing Area 47), that are of major, moderate or minor importance to fisheries. In this region, the deep--sea chondrichthyan fauna is currently represented by 50 shark, 20 batoid and 8 chimaera species. This guide includes full species accounts for 37 shark, 9 batoid and 4 chimaera species selected as being the more difficult to identify and/or commonly caught. Each species is described, depicted with a colour illustration and photo, and key distinguishing features of similar-looking species occurring in the same area are highlighted allowing for easy and accurate identification in the field. Keys to the shark and batoid orders and families, together with keys to chimaera and skate genera are also provided. This guide is intended to help fishery workers collecting catch data in the field in the identification of the cartilaginous fish species they might encounter. It is conceived to be updatable, offering the possibility to add new species accounts as new species are described."--Publisher's description.

Book Global overview on the status of sharks fisheries and management

Download or read book Global overview on the status of sharks fisheries and management written by Laurence Fauconnet and published by . This book was released on 2009 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'exploitation des requins a considérablement augmenté pendant les trente dernières années, en grande partie pour satisfaire la demande croissante en ailerons de requins pour le marché chinois. La plupart des espèces de sélaciens ont été prouvé particulièrement vulnérables à une intense exploitation, en grande partie en raison de leur longue espérance de vie, maturation tardive et faible fécondité. Malgré la multiplication des preuves scientifiques de déclins de grande ampleur auquels sont sujets les populations de sélaciens, ces études ont presque immédiatement reçu des critiques, notamment concernant l'utilisation des CPUE comme indice d'abondance. Les évaluations de stocks sont considérées comme le moyen le plus rigoureux d'évaluer l'état d'un stock mais cette méthode, très exigeante en données, n'est appliquable que rarement. La gestion des pêcheries de requins demeure une faible priorité dans la plupart des régions et la mise en oeuvre de Plans Nationaux d'Action pour la Conservation et la Gestion des Requins (NPOA-Sharks), en réponse à l'appel lancé par la FAO en 1999 avec le Plan International d'action (IPOA-Sharks), a été relativement lente jusqu'à présent. Les objectifs généraux de cette étude sont (i) d'analyser les tendances dans les captures globales de requins, par pays et par espèce depuis le début des déclarations en 1950, (ii) d'évaluer l'importance des pêcheries de requins au sein des organisations nationales et internationales les plus impliquées dans leur gestion, (iii) évaluer l'état des populations qui ont été évaluées quantitativement et, (iv) mettre en avant les espèces et régions prioritaires pour la gestion. Nous utilisons la base de données "Total Fishery Production (1950-2007)" de la FAO pour identifier les pays qui déclarent les plus importantes captures de requins, les débuts et l'ampleur des déclarations par espèces et les espèces déclarées en plus grandes quantités. Nous examinons six organisations internationales et les treize pays qui ont mis en place un NPOA-Sharks pour caractériser au sein de chacun d'eux les pêcheries de sélaciens, estimer l'ampleur de leur gestion. Les principaux obstacles qu'ils rencontrent pour évaluer l'état de leurs stocks sont classés selon trois critères : manque de données de pêche, manque de données biologiques, faible préoccupation pour la gestion de ces stocks. Nous assemblons toutes les évaluations de stock menées à ce jour sur les populations de requins pour évaluer les stocks pour lesquels un modèle de dynamique de population a été developpé. De même, nous identifions l'état de ces stocks, le modèle utilisé et le niveau d'incertitude dans les résultats de ces analyses. Nous comparons les séries temporelles de données entre les évaluations de stocks et la base de données de la FAO pour identifier les principales différences. Nous identifions les espèces ou groupes d'espèces les plus vulnérables à l'exploitation en se basant sur leurs traits d'histoire de vie en utilisant l'étude de Garcia et al (2006). Nous utilisons la base de données "Commodities production and Trade (1976-2006)" de la FAO pour identifier les pays qui exportent les plus grandes quantités de viande et d'ailerons de requins, puis nous déterminons avec la base de données "Total Fishery Production" les espèces les plus pêchées au sein de ces pays. Pour les ailerons, nous comparons ces résultats avec l'étude menée par Clarke et al, en 2006.

Download or read book State of World Aquaculture 2006 written by Food and Agriculture Organization of the United Nations. Inland Water Resources and Aquaculture Service and published by Food & Agriculture Org.. This book was released on 2006 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture is developing, expanding and intensifying in almost all regions of the world, except in sub-Saharan Africa. Although the sector appears to be capable of meeting the gap between future demand and supply for aquatic food, there are many constraints and challenges which must be addressed in order to at least maintain the present level of per capita consumption at the global level. Key issues are the need for enhanced enforcement of regulation and better governance of the sector, as well as greater producer participation in the decision-making and regulation process. This publication examines past trends in aquaculture development as well as the current global status, drawing on a number of national and regional reviews.
