King Crabs Of The World

by Bradley G. Stevens, King Crabs Of The World Books available in PDF, EPUB, Mobi Format. Download King Crabs Of The World books, With species existing in all subpolar seas, king crabs are one of the most valuable seafoods. Major fluctuations in their abundance have stimulated a flurry of research and a rapid expansion of the scientific literature in the last decade. King Crabs of the World: Biology and Fisheries Management consolidates extensive knowledge on the biology, systematics, anatomy, life history, and fisheries of king crabs and presents it in a single volume. This book is the first comprehensive scientific reference devoted to the biology and fisheries of king crabs. The first part of the book describes king crabs and their place in the world, covering geographic distribution, depth and temperature ranges, and maps of known habitats. Chapters examine phylogenetic relationships, evolutionary history and phylogeography, internal and external anatomy of king crabs, and the history of North Pacific fisheries. There is also a chapter that presents a comprehensive overview of diseases and other anomalies of king crabs. The second part of the book describes the life history and biology of various king crab species, including embryonic development and environmental factors, the development and biology of larvae, the ecology and biology of juvenile stages, reproductive strategies of fished species, and the growth and feeding of king crabs and their ecological impacts. The third part of the book discusses human and environmental interactions with king crabs through fisheries, management, and ecosystems. Topics include the impacts of fishing—bycatch, handling, and discard mortality—king crab aquaculture and stock enhancement, and king crabs from various regions such as Southern Hemisphere waters, the Barents Sea, and Alaska. A chapter synthesizing various aspects of king crab biology provides an ecosystem-scale perspective and the final chapter presents the author’s outlook on the future of king crab research and populations.

Walking Sideways

by Judith S. Weis, Walking Sideways Books available in PDF, EPUB, Mobi Format. Download Walking Sideways books, The world's nearly 7,000 species of crabs are immediately recognizable by their claws, sideways movement, stalked eyes, and thick outer shells. These common crustaceans are found internationally, thriving in various habitats from the edge of the sea to the depths of the ocean, in fresh water or on land. Despite having the same basic body type as decapod crustaceans-true crabs have heavy exoskeletons and ten limbs with front pincer claws-crabs come in an enormous variety of shapes and sizes, from the near microscopic to the giant Japanese spider crab. In Walking Sideways, Judith S. Weis provides an engaging and informative tour of the remarkable world of crabs, highlighting their unique biology and natural history. She introduces us to recently discovered crabs such as the Yeti crab found in deep sea vents, explains what scientists are learning about blue and hermit crabs commonly found at the shore, and gives us insight into the lifecycles of the king and Dungeness crabs typically seen only on dinner plates. Among the topics Weis covers are the evolution and classification of crabs, their habitats, unique adaptations to water and land, reproduction and development, behavior, ecology, and threats, including up-to-date research. Crabs are of special interest to biologists for their communication behaviors, sexual dimorphism, and use of chemical stimuli and touch receptors, and Weis explains the importance of new scientific discoveries. In addition to the traditional ten-legged crabs, the book also treats those that appear eight-legged, including hermit crabs, king crabs, and sand crabs. Sidebars address topics of special interest, such as the relationship of lobsters to crabs and medical uses of compounds derived from horseshoe crabs (which aren't really crabs). While Weis emphasizes conservation and the threats that crabs face, she also addresses the use of crabs as food (detailing how crabs are caught and cooked) and their commercial value from fisheries and aquaculture. She highlights other interactions between crabs and people, including keeping hermit crabs as pets or studying marine species in the laboratory and field. Reminding us of characters such as The Little Mermaid's Sebastian and Sherman Lagoon's Hawthorne, she also surveys the role of crabs in literature (for both children and adults), film, and television, as well in mythology and astrology. With illustrations that offer delightful visual evidence of crab diversity and their unique behaviors, Walking Sideways will appeal to anyone who has encountered these fascinating animals on the beach, at an aquarium, or in the kitchen.

Working On The Edge

by Spike Walker, Working On The Edge Books available in PDF, EPUB, Mobi Format. Download Working On The Edge books, No profession pits man against nature more brutally than king crab fishing in the frigid, unpredictable waters of the Bering Sea. The yearly death toll is staggering (forty-two men in 1988 alone); the conditions are beyond most imaginations (90-mph Arctic winds, 25-foot seas, and super-human stretches of on-deck labor); but the payback, if one survives can be tens of thousands of dollars for a month-long season. In a breathtaking, action-packed account that combines his personal story with the stories of survivors of the industry's most harrowing disasters, Spike Walker re-creates the boom years of Alaskan crab fishing--a modern-day gold rush that drew hundreds of fortune-and adventure-hunters to Alaska's dangerous waters--and the crash that followed.

Time Bandit

by Andy Hillstrand, Time Bandit Books available in PDF, EPUB, Mobi Format. Download Time Bandit books, “Many brave hearts are asleep in the deep, so beware, beware,” goes the chorus of an old sailors’ sing-along that celebrates the allure and danger of the seafaring life. But make no mistake–there truly is much to beware for those who are drawn to risk their lives and seek their fortunes upon the waves. And perhaps none take more chances than the men and women who brave the tempestuous, bountiful waters of the Bering Sea. Season after season, they bond and battle with its icy depths, determined to reap yet one more rewarding harvest while eluding the ever-present threat of sudden, certain death. And among the rapidly diminishing ranks of these die-hard salts, brothers Andy and Johnathan Hillstrand have forged a reputation as fierce masters of their treacherous, enthralling trade. If you’ve watched their exploits on TV’s Deadliest Catch, you’ve only scratched the surface. To read Time Bandit is to step into their skins, smell the sea air, feel the frigid wind, and know with all your senses the exhilarating, and terrifying life on the edge. Natives of tiny, fishing hamlet, Homer, Alaska; sons of a hard-bitten, highly successful fisherman; and born with brine in their blood, the Hillstrand boys couldn’t imagine a life without a swaying deck underfoot and a harvest of mighty Alaskan king crabs waiting to be pulled from the ocean floor. In pursuit of their daily catch, the brothers brave ice floes and heaving waves 60 feet high, the perils of 1000-lb steel traps thrown about by the punishing wind, and the constant menace of the open, hungry water. Even the brothers’ downtime on land–where the deadly realities of the unforgiving sea are never far from their minds–is lived as if borrowed: fast and hard, haunted by the knowledge that the next season at sea could end asleep in the deep. Here is the Hillstrands’ own heartfelt hymn to the brutally hard, gloriously independent, and mysteriously soul-satisfying life that has earned them their daily bread and defined their existence. By turns raucous and reflective, exhilarating and anguished, enthralling, suspenseful, and wise, Time Bandit chronicles a larger-than-life love affair as old as civilization itself–a love affair between striving, willful man and inscrutable, enduring nature.

In The Wrong Place Alien Marine Crustaceans Distribution Biology And Impacts

by Bella S. Galil, In The Wrong Place Alien Marine Crustaceans Distribution Biology And Impacts Books available in PDF, EPUB, Mobi Format. Download In The Wrong Place Alien Marine Crustaceans Distribution Biology And Impacts books, In The Wrong Place: Alien Marine Crustaceans - Distribution, Biology And Impacts provides a unique view into the remarkable story of how shrimps, crabs, and lobsters – and their many relatives – have been distributed around the world by human activity, and the profound implications of this global reorganization of biodiversity for marine conservation biology. Many crustaceans form the base of marine food chains, and are often prominent predators and competitors acting as ecological engineers in marine ecosystems. Commencing in the 1800s global commerce began to move hundreds – perhaps thousands – of species of marine crustaceans across oceans and between continents, both intentionally and unintentionally. This book tells the story of these invasions from Arctic waters to tropical shores, highlighting not only the importance and impact of all prominent crustacean invasions in the world's oceans, but also the commercial exploitation of invasive crabs and shrimps. Topics explored for the first time in one volume include the historical roots of man's impact on crustacean biogeography, the global dispersal of crabs, barnacle invasions, insights into the potential scale of tropical invasions, the history of the world's most widely cultured shrimp, the invasive history and management of red king crabs in Norway, Chinese mitten crabs in England, and American blue crabs in Europe, the evolutionary ecology of green crabs, and many other subjects as well, touching upon all ocean shores.
