Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Tradicionaly recreational fishery management has focused on dynamics of individual fish populations. Attempts to improve fish populations center on manipulations of harvest or the population itself. However, outcomes of fishery management actions have been difficult to forecast. Ecological processes within fish communities and angler responses can produce unanticipated effects. This thesis documents my research on these processes in Lake Mendota to make fishery management a more holistic, predictive science. A food web manipulation began in 1987. This project used several fishery management tools to increase the biomass of piscivorus gamefish to evaluate food web manipulation as a water quality management tool. Forecasting and measuring direct and indirect effects of the manipulation were important objetives. To forecast how management would affect piscivore populations, and their consumption of prey, I combined two computer models: an age-structured population model and a bioenergetics model. This technique predicted how size, abundance, and consumption of piscivores changed with stocking rates and sire limits. A walleye stocking program that yielded 8,000 yearling/year doubled consumption demand; adding a 381-mm minimum size limit achieved another 50% increase. To predict consequences of piscivore management for prey populations, I studied predador and prey fish populations. Highley variable prey recuitment made forecasting impacts of piscivory difficult. Based on historic recruitment patterns, enhanced walleye populations could consume 65-100% of young-of-year perch biomass produced in low recruitment years. When recruitment was high walleyes consumed less than 5% of the biomass. Translating predicted piscivore consumption into perch dynamics was accomplished by incorporating prey recruitment uncertainty. Angler response to piscivore enhancements was intense. Angler effort increased four-fold and harvest rates doubled to 60% per year. As a result, forescasts of piscivore consumption demand and the effectiveness of food web manipulation dependend heavily on responses of sport anglers to piscivore populations. Hence, a better understanding of angler dynamics was required before ecological effects of fishery management actions could be predicted. I developed a predatory-prey model to study angler-piscivore interactions. This approach linked angler and fish dynamics, and provided the means to incorporate fish, anglers, and management actions within one framework.
