Available in PDF, EPUB and Kindle. Book excerpt: An international group of specialists presented these 53 papers at the sixth crab symposium in the Lowell Wakefield symposium series at the U. of Alaska in January of 2001. The main themes include crab life cycles, reproductive biology and behavior, recruitment and population dynamics, fisheries and stock assessment, environment and habitat, and fisheries management. Individual papers present the results of research on topics that include the bitter crab syndrome in Tanner crab, re-stratification of red king crab assessment, population structure of blue king crab, habitat use by juvenile crabs, the impact of the European green crab in the Pacific, and use of tag recapture data to estimate natural mortality.

Download or read book Population Genetics and Mating Structure of Blue King Crab Paralithodes Platypus written by Jennifer L. Stoutamore and published by . This book was released on 2014 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blue king crab (Paralithodes platypus Brandt, 1850) has been an economically important species in Alaska since the 1970s, but its abundance has decreased substantially since the mid-1980s. Despite Fishery closures, abundances have not rebounded to previous levels. This failure has highlighted the dearth of information on the species and the need for research into genetic population structure and reproductive biology in order to better inform management efforts. Blue king crab tissue and hemolymph samples were collected from eight geographically distinct locations in Southeast Alaska, the Bering Sea, and Russia (n = 770). Allele frequencies at 10 polymorphic microsatellite loci were compared among collection locations. Moderate genetic differences were detected among all locations (overall Fst = 0.027, SE = 0.005). Heterogeneity was detected among temporal samples collected at the Pribilof Islands and St. Matthew Island. Comparisons suggested allele frequencies within each location had changed over time. Mating structure was examined by genotyping 20 progeny from each of 44 blue king crab broods collected from 3 different locations in the Bering Sea. All evidence supported single paternity for this species. This study suggests that Alaskan blue king crab stocks be managed at the population level, monitored for temporal genetic changes, and that potential future enhancement activities incorporate the single paternity mating system into determinations of broodstock composition and number.

Download or read book Quantitative Fish Dynamics written by Terrance J. Quinn and published by Oxford University Press, USA. This book was released on 1999 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fields of fish population dynamics and stock assessment have seen major advances in the 1980s and 1990s, creating the need for a new synthesis. This text attempts that synthesis by presenting a contemporary approach for quantitative fisheries science that incorporates modern statistical and mathematical techniques. It emphasizes the link between biology and theory by explaining the assumptions inherent in the quantitative methods and models. The book covers key topics that are often overlooked in other texts, such as optimal harvesting, migratory stocks, and complex age and size-structured models. Quantitative Fish Dynamics is an ideal textbook for graduate and undergraduate courses in fish population dynamics and stock assessment. It is an indispensable reference work for fisheries scientists and others interested in conservation biology, fish and wildlife management, population ecology, and statistical applications.

Available in PDF, EPUB and Kindle. Book excerpt: The Bering Sea, which lies between the United States and Russia, is one of the most productive ecosystems in the world and has prolific fishing grounds. Yet there have been significant unexplained population fluctuations in marine mammals and birds in the region. The book examines the Bering Sea ecosystem's dynamics and the relationship between man and the ecosystem, in order to identify potential reasons for the population fluctuations as well as identify ways the Sea's living resources can be better managed by government.
