Operational Plan: Reproductive and Biological Sampling of Yelloweye Rockfish (Sebastes Ruberrimus) and Black Rockfish (Sebastes Melanops) from Southeast Alaska Sport and Commercial Fisheries


Book Description

There is a limited understanding of the reproductive biology of yelloweye rockfish (Sebastes ruberrimus) and black rockfish (S. melanops) in Alaskan waters. The purpose of this project is to sample yelloweye and black rockfish in order to estimate maturity schedules (length and age at maturity) and fecundity (both absolute and relative) in Southeast Alaska. An understanding of the reproductive biology of these rockfish species is necessary for science-based management and population dynamics modeling for stock assessment purposes. This project will estimate important life history parameters for these rockfish in Southeast Alaska.










California's Living Marine Resources


Book Description

This 592-page spiral-bound reference provides a baseline of information for all those involved with managing living marine resources in California and chronicles changes that have occurred in many of the state’s fisheries. Organized by marine ecosystems: bays and estuaries, nearshore and offshore. Includes illustrated species descriptions with details of biological knowledge, fishery history, landings data, population status and references. Also includes sections on marine birds and mammals and appendices containing management considerations (by species), a glossary of technical terms and acronyms and fishing gear illustrations. Jointly produced by the California Sea Grant Extension Program and the California Department of Fish and Game following the passage of the Marine Life Protection Act in January 1999.




Stock Identification Methods


Book Description

Stock Identification Methods, 2e, continues to provide a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, this valuable resource offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach. Describes 18 distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis Focuses on the challenges of interpreting data and managing mixed-stock fisheries




The Rockfishes of the Northeast Pacific


Book Description

"A major landmark contribution to fisheries science and fish ecology. Rockfish populations are in a severe decline throughout the Northeastern Pacific, and the need for a deep understanding of their biology, ecology, and management has never been more critical. This book addresses all aspects of our current knowledge of this diverse and interesting group of groundfish species, and it is written clearly and with humor. An outstanding work!"--Larry G. Allen, California State University, Northridge "Quite simply the best account ever of the fascinating, diverse, and valuable rockfishes. If you are interested in the marine fishes of the Pacific Coast, you need this book."--Peter B. Moyle, author of Inland Fishes of California




Climate Change and Human Responses


Book Description

This book contributes to the current discussion on climate change by presenting selected studies on the ways in which past human groups responded to climatic and environmental change. In particular, the chapters show how these responses are seen in the animal remains that people left behind in their occupation sites. Many of these bones represent food remains, so the environments in which these animals lived can be identified and human use of those environments can be understood. In the case of climatic change resulting in environmental change, these animal remains can indicate that a change has occurred, in climate, environment and human adaptation, and can also indicate the specific details of those changes.
