Download or read book Edible Sea Urchins Biology and Ecology written by John M. Lawrence and published by Elsevier. This book was released on 2001-05-21 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea urchins are a major component of marine environments found throughout the world's oceans. A major model for research in developmental biology, they are also of major economic importance in many regions and interest in their management and aquaculture has increased greatly in recent years. This book provides a synthesis of biological and ecological characteristics of sea urchins that are of basic scientific interest and also essential for effective fisheries management and aquaculture. General chapters consider characteristics of sea urchins as a whole. In addition, specific chapters are devoted to the ecology of 17 species that are of major commercial interest and ecological importance. Features include: • A synthesis of what is known about the basic biological characteristics of the sea urchin, useful for the direction of future research. • Case histories of 17 species that illustrate their ecological role in a variety of environments. • With the catastrophic decline in fisheries resulting primarily from over-fishing, it is essential that the populations be managed effectively and that aquaculture be developed. This book provides knowledge of the biology and ecology of the commercially important sea urchins that will contribute to these goals. • The only book available in present literature devoted to sea urchins. With this new title experts provide a broad synthetic treatment and in depth analysis of the biology and ecology of sea urchins from around the world, designed to provide an understanding of the group and the basis for fisheries management and aquaculture.

Book excerpt: "Sea urchins are harvested worldwide, the majority destined for the Japanese market. Japan is by far the world's largest importer and consumer of sea urchin roe. In 2002, Japan imported about 18,525 metric tons (mt) of live sea urchins and sea urchin roe valued at about 247 million dollars, an increase of more than ten-fold in volume and 12-fold in value from 1975. Much of this increase was due to good demand, decreased domestic harvest, and consequent rise in price for sea urchin roe. Fresh sea urchin roe was the dominant product imported into Japan, representing as much as 49 percent in value in 2002. The United States has become the largest supplier of fresh roe to Japan, providing over 45 percent in value and 39 percent in volume of the total. Differences in peak fishing seasons in Japan (spring through summer) and the United States (fall through spring) have benefitted U.S. exporters in marketing sea urchin roe to Japan. Japan was the world's largest harvester of sea urchins until 1984. Since 1987, Japanese harvests have declined steadily due mainly to declining stock abundance. The harvest in 2002 of 13,000 mt was less than half of the record high landings which occurred in 1969. From 1987 to 2001, landings in the United States have exceeded Japanese landings. In 2001, sea urchins were harvested in six states: Alaska (1,166 mt), Washington (344 mt), Oregon (571 mt), California (5,951 mt), Maine (4,491 mt), and Rhode Island (0.1 mt). Most fresh sea urchin roe are sold through auction at the Tokyo Central Wholesale Market. Although quality of roe is the most important factor in determining prices, total supply (domestic and imported roe) is also significant. In 2002, the highest price for imported roe occurred in January. High prices for Japanese roe occurred in January and September, reflecting the low availability of roe during these months. Japan regulates imports of sea urchin products with import tariffs. As the United States and Japan are signatories to the World Trade Organization (WTO), WTO tariffs apply to U.S. exports of sea urchin products: 7 percent for fresh, frozen, or salted sea urchin roe, and 10 percent for prepared or preserved products, including those in airtight containers. There is no tariff for live sea urchins. Tariff rates are calculated as a percentage of total cost, including insurance and freight. Sea urchin roe shipped from Los Angeles is considered to be the best in Japan's import market. The future market for sales of U.S. sea urchins to Japan depends to a large extent on Japanese sea urchin harvest. Because domestic harvest is not likely to increase in the short term, increased export of U.S. sea urchins and sea urchin roe has significant potential."--Executive summary.

Available in PDF, EPUB and Kindle. Book excerpt: The world’s stocks of wild fish continue to decline, making the task of finding innovative, sustainable and socially acceptable methods of fisheries management more important than ever. Several new approaches from around the world have proved to be successful in stemming the decline whilst increasing fish catches, and under the editorship of McClanahan and Castilla this international team of authors have looked to these examples to provide the reader with carefully chosen case studies offering practical suggestions and solutions for problem fisheries elsewhere. Coverage includes: Community based fisheries Collaborative and co-operative fisheries management Coastal fisheries management The future for sustainable fisheries management Written by many of the world’s most experienced practitioners Fisheries Management: Progress toward sustainability is an important purchase for all fisheries scientists, managers and conservationists. All libraries in universities and research establishments where this area is studied and taught will find this book a valuable addition to their shelves.

Available in PDF, EPUB and Kindle. Book excerpt: Sea urchins and sea cucumbers are highly sought after delicacies growing in popularity globally. The demand for these species is rapidly outpacing natural stocks, and researchers and seafood industry personnel are now looking towards aquaculture as a means of providing a sustainable supply of these organism. Echinoderm Aquaculture is a practical reference on the basic biology and current culture practices for a wide range of geographically diverse echinoderm species. Echinoderm Aquaculture begins by examining the basic ecology and biology of sea urchins and sea cucumbers as well as the breadth of uses of these organisms as a source of food and bioactive compound. Subsequent chapters delineate the specific species of interest invarious geographic regions from around the world. Together, chapters provide a comprehensive coverage of culture practices. Echinoderm Aquaculture is a practical reference for researchers and industry personnel, and will serve as an invaluable resource to this rapidly growing segment of the aquaculture industry.

Available in PDF, EPUB and Kindle. Book excerpt: Sea urchins are a major component of the world ocean. They are important ecologically and often greatly affect marine communities. They have an excellent fossil record and consequently are of interest to paleontologists. Research has increased in recent years stimulated first by a recognition of their ecological importance and then because of their economic importance. Scientists around the world are actively investigating their potential for aquaculture. This book is designed to provide a broad understanding of the biology and ecology of sea urchins. Synthetic chapters consider biology of sea urchins as a whole to give a broad view. The topics of these chapters include reproduction, metabolism, endocrinology, larval ecology, growth, digestion, carotenoids, disease and nutrition. Subsequent chapters consider the ecology of individual species that are of major importance ecologically and economically. These include species from Japan, New Zealand, Australia, Europe, North America, South America and Africa. * First comprehensive book devoted to the biology and ecology of sea urchins * NEW chapter on Nutrition of Sea Urchins and Ecology of Diadema * Brand NEW illustrations * Hot NEW topic: Immunology of the Sea Urchin * Chapters written by internationally recognized experts * Each chapter revised and updated from the first edition * Biological chapters include reproduction, endocrinology, carotenoids and disease * Ecological chapters include species of major economic interest for fisheries and aquaculture
