Running Silver


Book Description

That one could “walk drishod on the backs” of schools of salmon, shad, and other fishes moving up Atlantic coast rivers was a not uncommon kind of description of their migratory runs during early Colonial times. Accounts tell of awe-inspiring numbers of spawners pushing their way upriver, the waters “running silver,” to complete life cycles that once replenished critical marine fisheries along the Eastern Seaboard. This is a hugely important, fascinating, and unique look at the fish of North America whose history and life-cycles and conservation challenges are poorly understood. Despite these primordial abundances, over the centuries these stocks were so stressed that virtually all are now severely depressed, with many biologically or commercially extinct and some simply forgotten. Running Silver will tell the story of the past, present and future of these sea-river fish. This important book will elevate public consciousness of the contrasts between the historical and the present to show the enormous legacy that has already been lost and to help inspire efforts to save what remains. Drawing on the author's thirty-year career as a scientist and educator with a passion for the native river fish of the North East, Running Silver tells the story of these endangered fish with a mix of research, historical accounts, anecdotes, personal experience, interviews, and images.




Ecosystem Based Management for Marine Fisheries


Book Description

Showing how big-picture patterns can help overcome the failures of conventional management, this book is ideal for students, researchers and professionals involved with marine fisheries. It explores not only the current practice of the 'ecosystem approach' to fisheries management but also its critical importance to even larger perspectives. The first section gives a valuable overview of how more and more of the complexity of real-world systems is being recognized and involved in the management of fisheries around the world. The second section then demonstrates how important aspects of real-world systems, involving population dynamics, evolution and behavior, remain to be taken into account completely. This section also shows how we must change the way we think about our involvement in, and the complexity of, marine ecosystems. The final chapters consider how, with the use of carefully chosen macroecological patterns, we can take important steps towards more holistic management of marine fisheries.

Politics of the Wild


Book Description

Politics of the Wild details the 353 species at risk in Canada and considers both the intrinsic and the instrumental reasons for protecting biological diversity. It examines the need for habitat protection, terrestrial protected areas such as national parks, marine species at risk, and the various legislative and interest group attempts to preserve biodiversity. Public policy on endangered species is considered from both historical and comparative perspectives, as is Canada's role in establishing international agreements--the Convention on International Trade in Endangered Species and the Convention on Biological Diversity--and the government's failure in recent years to meet the obligations of these and other environmental agreements. The final chapter looks at the Species at Risk Act (SARA) and its recent predecessor, Bill C-65, and reveals the difficulties of crafting and passing such legislation in an increasingly decentralized federal state such as Canada. Both legislative attempts were criticized--by the environmental policy community for not doing enough, and by the provinces and business for trying to do too much. All the while, diverse regional interests and economic imperatives run the risk of endangering far more than merely Canadian species at risk.




Fish Conservation


Book Description

Fish Conservation offers, for the first time in a single volume, a readable reference with a global approach to marine and freshwater fish diversity and fishery resource issues. Gene Helfman brings together available knowledge on the decline and restoration of freshwater and marine fishes, providing ecologically sound answers to biodiversity declines as well as to fishery management problems at the subsistence, recreational, and commercial levels. Written in an engaging and accessible style, the book: considers the value of preserving aquatic biodiversity offers an overview of imperiled fishes on a taxonomic and geographic basis presents a synthesis of common characteristics of imperiled fishes and their habitats details anthropogenic causes of decline examines human exploitation issues addresses ethical questions surrounding exploitation of fishes The final chapter integrates topics and evaluates prospects for arresting declines, emphasizing the application of evolutionary and ecological principles in light of projected trends. Throughout, Helfman provides examples, explores case studies, and synthesizes available information from a broad taxonomic, habitat, and geographic range. Fish Conservation summarizes the current state of knowledge about the degradation and restoration of diversity among fishes and the productivity of fishery resources, pointing out areas where progress has been made and where more needs to be done. Solutions focus on the application of ecological knowledge to solving practical problems, recognizing that effective biodiversity conservation depends on meeting human needs through management that focuses on long term sustainability and an ecosystem perspective.
