Book Description
The genus Perca includes only three species of fish, but they are ubiquitous and abundant in freshwater and brackish environments of the northern hemisphere, from North America to Europe and Asia. These species are important both ecologically and economically. In Biology of Perch, world-renowned specialists review and update the biology of these fi
Xenobiotics in Fish

ISBN: 1461547032
Category : Science

Pages : 226
Book Description
Aquaculture is rapidly becoming a major source of fish protein used to meet the nutritional needs of humans. As the aquaculture industry grows, exposure of farmed fish to environmental contaminants, and the need for chemical therapeutic agents for fish, will increase. This book is designed to bring together authorities worldwide on the regulation of environmental contaminants and food chemicals and researchers investigating the metabolism and disposition of foreign chemicals (xenobiotics) in fish species.
Fisheries and Aquaculture - Volume III

ISBN: 1848261101

Languages : en
Pages : 472
Book Description
Fisheries and Aquaculture theme is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Fisheries are a major life support system and the main purpose of this theme on Fisheries and Aquaculture is to provide baseline information and latest knowledge at the dawn of this century to facilitate vital fisheries recovery before their irreparable collapse. This Theme on Fisheries and Aquaculture is divided into five topics. It starts with discussions on major issues and challenges in “Harvesting the Seas”, with emphasis on the role and importance of the fisheries sector and its environment, and introduces trends and perspectives in marine fisheries, including allocation of use rights, subsidies, and port management. The next two topics present an in-depth and detailed knowledge on fish and other aquatic living resources that are commercially exploited and/or farmed. The third topic on Inland Fisheries presents salmonid fish, eels, shad, whitefish and smelt, carp, perch, pike and bass, tilapia, frog, and crustaceans. The fourth topic presents a comprehensive review of trends and perspectives in Aquaculture: Principles and Prospects. The fifth topic on Economics of Fisheries and Aquaculture reviews the latest views and concepts useful to apprehend the fisheries management regime, including a comparative static economic theory and a dynamic theory of fishery, spatial bioeconomic dynamics and role of international law in the management of marine fisheries, rights-based and community fisheries management, aquaculture economics, and game theory and fisheries. These five volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.
Monitoring the State of the St. Lawrence River

Book Description
Six government partners - Environment Canada, Fisheries and Oceans Canada, the Canadian Space Agency, Parks Canada Agency, the Ministère du Développement durable, de l'Environnement et des Parcs du Québec, the Ministère des Ressources naturelles et de la Faune du Québec - and Stratégies Saint-Laurent, a nongovernmental organization that works actively with riverside communities, are pooling their expertise and efforts to provide Canadians with information on the state of the St. Lawrence and long-term trends affecting it. To this end, environmental indicators have been developed on the basis of data collected as part of each organization's ongoing environmental monitoring activities. This fact sheet is about the Shellfish Water Quality Protection Program (SWQPP). This program is a monitoring network to assess the bacterial water quality in shellfish growing areas.
Ecological Effects of Water-level Fluctuations in Lakes
Author: Karl M. WantzenPublisher: Springer Science & Business Media
ISBN: 1402091923
Category : Technology & Engineering
Languages : en
Pages : 184
Book Description
Most aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.

Book Description
Beginning with the Grand Rapids Dam in the 1960s, hydroelectric development has dramatically altered the social, political, and physical landscape of northern Manitoba. The Nelson River has been cut up into segments and fractured by a string of dams, for which the Churchill River had to be diverted and new inflow points from Lake Winnipeg created to manage their capacity. Historic mighty rapids have shrivelled into dry river beds. Manitoba Hydro's Keeyask dam and generating station will expand the existing network of 15 dams and 13,800 km of transmission lines. In Our Backyard tells the story of the Keeyask dam and accompanying development on the Nelson River from the perspective of Indigenous peoples, academics, scientists, and regulators. It builds on the rich environmental and economic evaluations documented in the Clean Environment Commission’s public hearings on Keeyask in 2012. It amplifies Indigenous voices that environmental assessment and regulatory processes have often failed to incorporate and provides a basis for ongoing decision-making and scholarship relating to Keeyask and resource development more generally. It considers cumulative, regional, and strategic impact assessments; Indigenous worldviews and laws within the regulatory and decision-making process; the economics of development; models for monitoring and management; consideration of affected species; and cultural and social impacts. With a provincial and federal regulatory regime that is struggling with important questions around the balance between development and sustainability, and in light of the inherent rights of Indigenous people to land, livelihoods, and self-determination, In Our Backyard offers critical reflections that highlight the need for purposeful dialogue, principled decision making, and a better legacy of northern development in the future.
