DOWNLOAD EBOOKWalleye, the holy grail of game fish: on catching them, understanding their biology and history, and ensuring their survival Among the more than 34,000 species of fish, few have the walleye’s following—among anglers and diners, states conferring official status on the fish, and towns battling for recognition as the Walleye Capital of the World. And among those passionate fans, few know the walleye as well as Paul J. Radomski does—a fisheries biologist, lake ecology scientist, and old fisherman. In Walleye: A Beautiful Fish of the Dark he unspools the mysteries of this fascinating fish. Radomski looks at walleye from every angle, with something to say to the curious naturalist, committed ecologist, and avid fishing enthusiast. People who view walleye as the “lion of the lakes” might be surprised to learn that rivers are their ancestral habitat. Some might wonder about the name “wall-eye,” a nod to an evolutionary adaptation to dark water environments. Others might simply ask: why walleye? What are they, where do they exist, how do they survive, and how have people come to depend on them? Radomski discusses the principles and pitfalls of managing this predator of the twilight (and the history and methods of doing so) and shares his informed perspective on when and where stocking is prudent. Finally, he explores three of the best walleye lakes: Winnebago, the largest inland walleye fishery in Wisconsin, and Mille Lacs and Red Lake in Minnesota. From the simple pleasures of fishing for walleye to the most pressing questions about how this species survives, this book is the best word on this beautiful fish of the dark.

DOWNLOAD EBOOKQuantitative modeling methods have become a central tool in the management of harvested fish populations. This book examines how these modeling methods work, why they sometimes fail, and how they might be improved by incorporating larger ecological interactions. Fisheries Ecology and Management provides a broad introduction to the concepts and quantitative models needed to successfully manage fisheries. Walters and Martell develop models that account for key ecological dynamics such as trophic interactions, food webs, multi-species dynamics, risk-avoidance behavior, habitat selection and density-dependence. They treat fisheries policy development as a two-stage process, first identifying strategies for varying harvest in relation to changes in abundance, then finding ways to implement such strategies in terms of monitoring and regulatory procedures. This book provides a general framework for developing assessment models in terms of state-observation dynamics hypotheses, and points out that most fisheries assessment failures have been due to inappropriate observation model hypotheses rather than faulty models for ecological dynamics. Intended as a text in upper division and graduate classes on fisheries assessment and management, this useful guide will also be widely read by ecologists and fisheries scientists.

It describes, by reciprocity, the vulnerability of ecosystems, resources, heritage, human health and, consequently, economic and social sectors. it considers climate scenarios and socio-economic status indicators research, design strategies and patterns of adaptation, development of innovative monitoring systems, analysis of perceptions of major hazards and valuation of ecosystem services.
