Book Description
Lake trout (Salvelnus namaycush) were the dominant coldwater predator in Lake Huron until population crashes occurred in the 1940s and 1950s. Since that time, international rehabilitation efforts directed at lake trout have been implemented. To further lake trout rehabilitation efforts in Ontario waters of Lake Huron, the Ontario Ministry of Natural Resources drafted the 1996 Lake Trout Rehabilitation Plan for Lake Huron (Canadian jurisdiction) using the continuum concept for guidance. Using the 1996 Plan objectives and evaluation criteria as benchmarks, progress towards rehabilitation in each of the 16 Lake Trout Rehabilitation Zones (LTRZs) is described. Upon review, the intent of the goal and objectives from the 1996 plan were deemed to be sound. However, revisions to the three objectives have been recommended that more closely relate them to the progression through rehabilitation. These revised objectives more closely reflect timelines associated with rehabilitation, and how these timelines differ between individual LTRZs as a result of differences in stocking history, stocking density, total annual mortality, and age to maturity. In addition to recommendations specific to the goals and objectives, recommendations for changes to rehabilitation strategies (i.e. stocking and exploitation control), evaluation criteria, and assessment tactics are made.--Document.

ISBN:
Category : Business & Economics
Languages : en
Pages : 576
Book Description
This volume focuses on the US-Canadian experience with the shared fishery resources of the Laurentian Great Lakes, a vast and complex ecosystem that holds 20 percent of the world's surface fresh water supply and a wide array of fish and fisheries. Written by scientists from federal, state, and provincial management agencies, contributions address current knowledge of the ecological, sociological, and policy issues that face the region's fishery managers and policy makers in both countries.

Book Description
Brown Trout: Biology, Ecology and Management A comprehensive guide to the most current research, history, genetics and ecology of the brown trout including challenging environmental problems The brown trout is an iconic species across its natural European distribution and has been introduced throughout the World. Brown Trout offers a comprehensive review of the scientific information and current research on this major fish species. While the brown trout is the most sought species by anglers, its introduction to various waters around the world is causing serious environmental problems. At the same time, introduction of exogenous brown trout lineages threats conservation of native gene pools of populations in many regions. The authors summarize the important aspects of the brown trout’s life history and ecology and focus on the impact caused by the species. The text explores potential management strategies in order to maintain numerous damaged populations within its natural distributional range and to ameliorate its impacts in exotic environments. The authors include information on a wide-range of topics such as recent updates in population genetics, evolutionary history, reproductive traits and early ontogeny, life history plasticity in anadromous brown trout and life history of the adfluvial brown trout and much more. This vital resource: Contains the latest research on the biology and ecology of brown trout Includes information on phylogeography, genetics, population dynamics and stock management Spotlights the brown trout’s introduction to regions around the world and the serious environmental impacts Offers a comprehensive review of conservation and management techniques Written for salmonid scientists and researchers, fishery and environmental managers, and students of population genetics, ecology and population dynamics, Brown Trout explores the most recent findings on the history, ecology and sustainability of this much-researched species.
