Management Systems for Riverine Fisheries by Thayer Scudder,Thomas Conelly Pdf

This paper is concerned specifically with the problems of river fisheries and associated management issues. It deals in particular with the scope for building on traditional practices, through the participation of traditional fishing communities, as a means of improving the quality of river fishery management. The paper reviews the most frequently encountered problems of riverine fisheries such as over-fishing due to population pressure or migration, and artifically induced environmental factors such as dams, pollution and deforestation. It lays stress on the importance of studying fishing communities, as well as strictly biological factors, and presents a four-stage analysis of the evolution of traditional riverine fisheries. Several undesirable consequences of this typical evolution, both on the resource itself and on traditional fishing communities, are identified and illustrated by case studies from the Amazon and the Zambesi. Certain types of traditional management strategies are examined and assessed for their future utility. The current ineffectiveness of many existing government river fisheries management policies is noted, either as a result of lack of resources or because they are inappropriate, often rooted in outdated colonial legislation. The lack of both limited access measures and of participation by local fishing communities are highlighted as major deficiencies. The paper concludes by linking these two features as crucial components of durable river management strategies for the future, although other possibilities for management are also reviewed and assessed. The paper contains a comprehensive bibliography for further reading.

Sustaining Marine Fisheries by National Research Council,Commission on Geosciences, Environment, and Resources,Ocean Studies Board,Committee on Ecosystem Management for Sustainable Marine Fisheries Pdf

Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.

Fish, Markets, and Fishermen by Suzanne Iudicello,Michael L. Weber,Robert Wieland Pdf

A significant number of the world's ocean fisheries are depleted, and some have collapsed, from overfishing. Although many of the same fishermen who are causing these declines stand to suffer the most from them, they continue to overfish. Why is this happening? What can be done to solve the problem. The authors of Fish, Markets, and Fishermen argue that the reasons are primarily economic, and that overfishing is an inevitable consequence of the current sets of incentives facing ocean fishermen. This volume illuminates these incentives as they operate both in the aggregate and at the level of day-to-day decision-making by vessel skippers. The authors provide a primer on fish population biology and the economics of fisheries under various access regimes, and use that information in analyzing policies for managing fisheries. The book: provides a concise statistical overview of the world's fisheries documents the decline of fisheries worldwide gives the reader a clear understanding of the economics and population biology of fish examines the management issues associated with regulating fisheries offers case studies of fisheries under different management regimes examines and compares the consequences of various regimes and considers the implications for policy making The decline of the world's ocean fisheries is of enormous worldwide significance, from both economic and environmental perspectives. This book clearly explains for the nonspecialist the complicated problem of overfishing. It represents a basic resource for fishery managers and others-fishers, policymakers, conservationists, the fish consuming public, students, and researchers-concerned with the dynamics of fisheries and their sustenance.

Evolving Approaches to Managing Marine Recreational Fisheries by Donald Leal,Vishwanie Maharaj Pdf

"Increasing coastal populations, rising recreational demand, and growing conflicts with other users are adding to the challenge of managing marine recreational fisheries today. Traditional regulations - such as daily bag limits and seasonal closures - are often not enough to control fishing impacts and they tend to generate greater discontent and lower economic benefits in the angling community as they become more restrictive. This volume is the first to examine management approaches that promise to better control fishing, generate more information on fishing impacts, and give anglers more freedom to enjoy their sport."--BOOK JACKET.

Alternative Arrangements for Marine Fisheries by Francis T. Christy, Jr. Pdf

The maintenance of the freedom of fishing in the face of the changing circumstances that were occurring at the time of this title’s original publication in 1973 had produced several damaging consequences. It had led to considerable waste, in both biological and economic terms, and had been the source of increasing conflict. This waste can only be prevented by the adoption of management measures and by the removal of the condition of free and open access. This book explores various techniques for this, and will be of interest to students of environmental management.

5 Easy Pieces by Daniel Pauly Pdf

5 Easy Pieces features five contributions, originally published in Nature and Science, demonstrating the massive impacts of modern industrial fisheries on marine ecosystems. Initially published over an eight-year period, from 1995 to 2003, these articles illustrate a transition in scientific thought—from the initially-contested realization that the crisis of fisheries and their underlying ocean ecosystems was, in fact, global to its broad acceptance by mainstream scientific and public opinion. Daniel Pauly, a well-known fisheries expert who was a co-author of all five articles, presents each original article here and surrounds it with a rich array of contemporary comments, many of which led Pauly and his colleagues to further study. In addition, Pauly documents how popular media reported on the articles and their findings. By doing so, he demonstrates how science evolves. In one chapter, for example, the popular media pick up a contribution and use Pauly’s conclusions to contextualize current political disputes; in another, what might be seen as nitpicking by fellow scientists leads Pauly and his colleagues to strengthen their case that commercial fishing is endangering the global marine ecosystem. This structure also allows readers to see how scientists’ interactions with the popular media can shape the reception of their own, sometimes controversial, scientific studies. In an epilog, Pauly reflects on the ways that scientific consensus emerges from discussions both within and outside the scientific community.

Sustainable Fishery Systems by Anthony Charles Pdf

This book provides a comprehensive attempt to adopt an 'integrated' interdisciplinary approach to the study of fisheries. Fisheries are discussed as holistic 'systems', with emphasis on their structure, operation and dynamics. The book's interdisciplinary approach is applied to an analysis of problems faced in pursuing 'sustainable fisheries', with emphasis on six dominant themes: sustainability, uncertainty, complexity, conflict, fishing rights and the nature of management. Within this discussion, several major directions in current fishery thinking are explored, notably the precautionary approach, the ecosystem approach, co-management, and robust management for resilient fisheries.

Fishery Co-Management by Robert S. Pomeroy,Rebecca Rivera-Guieb Pdf

During the last decade, there has been a shift in the governance and management of fisheries to a broaderapproach that recognizes the participation of fishers, local stewardship, and shared decision-making.Through this process, fishers are empowered to become active members of the management team,balancing rights and responsibilities, and working in partnership with government. This approach iscalled co-management.This handbook describes the process of community-based co-management from its beginning, throughimplementation, to turnover to the community. It provides ideas, methods, techniques, activities, checklists,examples, questions and indicators for the planning and implementing of a process of community-basedco-management. It focuses on small-scale fisheries (freshwater, floodplain, estuarine, or marine) indeveloping countries, but is also relevant to small-scale fisheries in developed countries and to themanagement of other coastal resources (such as coral reefs, mangroves, sea grass, and wetlands). Thishandbook will be of significant interest to resource managers, practitioners, academics and students ofsmall-scale fisheries.

The Behavior, Ecology and Evolution of Cichlid Fishes by Maria E. Abate,David L.G. Noakes Pdf

This volume constitutes the most recent and most comprehensive consideration of the largest family of bony fishes, the Cichlidae. This book offers an integrated perspective of cichlid fishes ranging from conservation of threatened species to management of cichlids as invasive species themselves. Long-standing models of taxonomy and systematics are subjected to the most recent applications and interpretations of molecular evidence and multivariate analyses; and cichlid adaptive radiations at different scales are elucidated. The incredible diversity of endemic cichlid species in African lakes is revisited as possible examples of sympatric speciation and as serious cases for management in complex anthropogenic environments. Extreme hydrology and bathymetry as driver of micro-allopatric speciation is explored in the African riverine hotspot of diversity of the lower Congo River. Dramatic new molecular evidence draws attention to the complex taxonomy and systematics of Neotropical cichlids including the crater lakes of Central America. Molecular genetics, genomics, imaging tools and field study techniques assess the roles of natural, sexual and kin selection in shaping cichlid traits and beyond. The complex behavioral adaptations of cichlids are considered from a number of sub-disciplines including sensory biology, neurobiology, development, and evolutionary ecology. Most importantly, this volume puts forth a wealth of new interpretations, explanatory hypotheses and proposals for practical management and applications that will shape the future for these remarkable fishes in nature as well as their use as models for the study of biology.
