Book excerpt: The first Wild Trout Symposium (1974) was sponsored by Trout Unlimited and the United States Department of the Interior. The second Symposium (1979) added the Federation of Fly Fisherman as a sponsor. Five years later (1984) the U.S. Department of Agriculture - Forest Service joined. In 1989 , the U.S. Environmental Protection Agency and the American Fisheries Society joined. These symposia began with a concentration on management, then recognized that more than 'management' was required in ongoing efforts to enhance wild salmonid fisheries. Subsequent symposia began to examine a broader range of environmental and social factors influencing wild salmonids. The originators hoped that each symposium would be a building block upon which the succeeding symposium could provide insights and research which future sessions could revisit. Along with the broadening of sponsorship, we have grown , we have gained recognition, and we look forward to expanding our contribution to the cause of wild salmonids. We hope these Proceedings will stimulate readers thinking and efforts on behalf of our wild salmonid resources , and plan to participate with us in Wild Trout V.

Book excerpt: This report is the synthesis by an editorial committee of information presented in working papers developed by Atlantic salmon scientists from the DFO Regions of Atlantic Canada and the Province of Quebec. It describes the 'Species Information', the first of five components of a DFO-outlined 'Conservation Status Report'. The 'Species Information' summarizes the population structure, biology, abundance, status, potential for recovery and scope for harm of Atlantic salmon. Highlights include: * the identification of 28 Atlantic salmon 'Conservation Units' CUs) in Eastern Canada i.e., groups of individuals likely exhibiting unique adaptations that are largely reproductively isolated from other groups, and that may represent an important component of a species' biodiversity; * the presentation of salmon population information for each of the CUs in terms of their abundance, trends thereof, and status relative to current conservation requirements and other reference points; * the presentation of a general decision-making framework to define thresholds between implementation of critical recovery actions, important new management actions/ interventions, and continuation of existing management/conservation approaches; * the presentation of evidence suggesting that the status of Eastern Canadian Atlantic salmon CUs is declining, particularly in the more southern extremities of its range. While some river populations on the south coast of insular Newfoundland (CU 5) appear to require management action, required direct recovery actions appear to be limited to Mainland Nova Scotia (i.e., Southern Upland) and Bay of Fundy (i.e., both outer and inner) salmon populations (i.e., CUs 14 - 17). River populations in Quebec and the southern Gulf of St. Lawrence are not considered to require recovery action although direct management actions for certain CUs may be required.

Download or read book Ecology of Atlantic Salmon and Brown Trout written by Bror Jonsson and published by Springer Science & Business Media. This book was released on 2011-05-03 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Destruction of habitat is the major cause for loss of biodiversity including variation in life history and habitat ecology. Each species and population adapts to its environment, adaptations visible in morphology, ecology, behaviour, physiology and genetics. Here, the authors present the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms of growth, migration, spawning and recruitment. Salmonids appeared as freshwater fish some 50 million years ago. Atlantic salmon and brown trout evolved in the Atlantic basin, Atlantic salmon in North America and Europe, brown trout in Europe, Northern Africa and Western Asia. The species live in small streams as well as large rivers, lakes, estuaries, coastal seas and oceans, with brown trout better adapted to small streams and less well adapted to feeding in the ocean than Atlantic salmon. Smolt and adult sizes and longevity are constrained by habitat conditions of populations spawning in small streams. Feeding, wintering and spawning opportunities influence migratory versus resident lifestyles, while the growth rate influences egg size and number, age at maturity, reproductive success and longevity. Further, early experiences influence later performance. For instance, juvenile behaviour influences adult homing, competition for spawning habitat, partner finding and predator avoidance. The abundance of wild Atlantic salmon populations has declined in recent years; climate change and escaped farmed salmon are major threats. The climate influences through changes in temperature and flow, while escaped farmed salmon do so through ecological competition, interbreeding and the spreading of contagious diseases. The authors pinpoint essential problems and offer suggestions as to how they can be reduced. In this context, population enhancement, habitat restoration and management are also discussed. The text closes with a presentation of what the authors view as major scientific challenges in ecological research on these species.
Download or read book The Aquaculture Controversy in Canada written by Nathan Young and published by UBC Press. This book was released on 2011-01-01 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The farming of aquatic organisms is one of the most promising but controversial new industries in Canada. The industry has the potential to solve food supply problems, but critics believe it poses unacceptable threats to human health, local communities, and the environment. This book is not about the methods and techniques of aquaculture, but it is an exploration of the controversy itself. The authors present the controversy as a multi-layered conflict about knowledge, rights, and development. Comprehensive and balanced, this book addresses one of the most contentious public policy and environmental issues facing the world today.

Book excerpt: This document is a continuation of the assessment of the conservation status of Atlantic salmon (Salmo salar L.) which began with 'Species Information' in 'Conservation Status Report, Atlantic Salmon in Atlantic Canada and Quebec: Part I - Species Information' (DFO and MRNF 2008). It addresses the anthropogenic considerations relevant to the conservation of Atlantic salmon, i.e., threats, existing protection, potential conservation targets, and significance of Atlantic salmon in Canada, and was assembled from text drafted by DFO and Quebec Provincial Atlantic salmon fisheries and habitat managers, economists and personnel in Aboriginal fisheries. Most elements of the document were reviewed in the presence of contributors, and 'external' scientists during a workshop held in March of 2007 (DFO 2007a). Highlights include: [1] a general discussion of 16 categories of threats potentially limiting to Atlantic salmon in Eastern Canada and a first attempt at a semi-quantitative evaluation of the degree of harm by each threat in terms of salmon affected and spawners lost within each of 28 Conservation Units; [2] evidence that the most wide-ranging habitat threats to Atlantic salmon originate from transportation infrastructure, agriculture, forestry and mining operations, and Municipal waste water discharge, and that the Maritime Provinces are the most severely impacted; [3] summary recovery efforts in place for the unlisted (Species at Risk Act, SARA) but severely depleted populations of Atlantic salmon in the outer Bay of Fundy (NS) and Southern Upland (NS) as well as the SARA-listed inner Bay of Fundy populations; [4] summary proposals for species rebuilding and habitat restoration as embodied in: a draft policy for the conservation of wild Atlantic salmon, an Atlantic salmon Endowment Fund, an Implementation Plan addressing Resolutions and Agreements of the North Atlantic Salmon Conservation Organization (NASCO), and governance and regulatory reform for aquaculture management; and [5] evidence that more than 40,000 Aboriginal Peoples in more than 50 communities through Atlantic Canada and Quebec can be said to be dependent on the traditional values of the Atlantic salmon resource.

Available in PDF, EPUB and Kindle. Book excerpt: This bulletin examines issues related to concerns that farmed salmon are interacting & adversely impacting the production & sustainability of wild Atlantic salmon stocks of the Maritime Provinces. It begins with an overview of the salmon farming industry in the Maritimes & Maine and examines the status of wild Atlantic salmon stocks in the Maritimes generally and also in two specific stocks. Factors potentially affecting wild salmon abundance are then discussed along with the evidence of wild/farmed salmon interaction in Maritime rivers & other locations. This is followed by a review of potential ecological, behavioural, disease, & genetic impacts of such interaction; a prediction of interaction impacts using a life history model; the conventions, regulatory controls, & policies relevant to the issues at hand; and the scientifically based options for mitigation of the impacts of wild/farmed salmon interaction. The final sections outline fishery management considerations & recommendations for further research.
