Book Description
The harvest of Alaska king crabs in the North Pacific and Bering Sea reaches about 18 million pounds per year, one-tenth of the bonanza 1980s catch. While king crab stocks are recovering from the crash, efforts such as this book on standardizing data collection promise to further improve fishery management. Geared to fishery observers, shoreside samplers, shellfish researchers, and fishermen, the book is illustrated with line drawings, maps, and numerous color photos, and it is printed on waterproof paper. Topics include taxonomy, life history, distribution, anatomy, and diseases. The authors are expert crab biologists at Alaska Department of Fish and Game, the agency responsible for managing the crab fishery.

Book Description
"This important publication enables standardization of data collection by fisheries observers and shoreline samplers, crab and shellfish biologists, and fishermen. Wide use of the book promises to improve data accuracy, and thus promote good management for these commercially important crabs. When data are collected citing this publication, there should be little or no ambiguity as to measurements made and definitions used. This guide is not all inclusive, but is intended to identify structures and organs, measurements and descriptions, and techniques that are commonly used in field studies"--p. vi.

Book Description
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, sys

Book Description
Arctic marine ecosystems are among the most productive and most vulnerable in the world, both from an economic and ecological perspective of growing accessibility. The complexity of Arctic marine ecosystems and their location poses challenges for management, valuation, and the establishment of sound policy to protect them. This special issue of Temanord presents papers from a workshop devoted to this topic. In October 2013, a group of multidisciplinary experts on marine invasive species and the Arctic came together in Esbjerg, DK for a two-day workshop titled: “Marine Invasive Species in the Arctic: Management Issues.” Attendees of the workshop came from academic, governmental and scientific institutions in Denmark and the Faroe Islands, Sweden, Norway, Finland, Iceland, Canada, and the United States. This volume presents papers based on the presentations of the workshop speakers.

Book Description
This handy, fully illustrated guide is designed to help researchers and scientists identify squids and octopods found in the eastern North Pacific Ocean and the Bering Sea, regions that have been difficult to sample because of their rough seas and thus have been poorly known until now. Printed on waterproof paper, the book describes and illustrates forty-four species, with full scientific details and aids to identification."
