Book Description
In the past, the Pacific Salmon Commission has used run reconstruction models to assign stock of origin to sockeye salmon (Oncorhynchus nerka) catches in the Fraser River First Nations fishery. Sockeye salmon catches from this fishery have also been allocated to stock groups using linear discriminant function analysis of scale parameters. This latter method has been applied to fishery catches from which scale proportions and catches derived using the two techniques.

Book Description
Drawing on a number of case studies from around the world, this publication considers how the local knowledge and practices of indigenous fishing communities are being used in collaboration with scientists, government managers and non-governmental organisations to establish effective frameworks for sustainable fisheries science and management. It seeks to contribute towards achieving the goal of establishing international responsibility for the ethical collection, preservation, dissemination and application of fishers' knowledge.

Book Description
The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Book Description
Involving Indigenous peoples and traditional knowledge into natural resource management produces more equitable and successful outcomes. Unfortunately, argue Anne Ross and co-authors, even many “progressive” methods fail to produce truly equal partnerships. This book offers a comprehensive and global overview of the theoretical, methodological, and practical dimensions of co-management. The authors critically evaluate the range of management options that claim to have integrated Indigenous peoples and knowledge, and then outline an innovative, alternative model of co-management, the Indigenous Stewardship Model. They provide detailed case studies and concrete details for application in a variety of contexts. Broad in coverage and uniting robust theoretical insights with applied detail, this book is ideal for scholars and students as well as for professionals in resource management and policy.

Book Description
Up-to-date information, knowledge and research in progress in scientific fields related to natural production of juvenile Atlantic salmon and some other ecologically similar fluvial salmonids is contained in the 25 papers and 12 abstracts contained in this publication, which were prepared for an international symposium held in St. John's, Newfoundland. Studies relate to stream ecology, invertebrates and predators, habitat improvement, competitive effects, behaviour and dispersal, habitat and production of juvenile salmon, population dynamics and relationships of juvenile salmon estimates to smolt yields. A list of participants at the conference is also provided.
