Shallow lakes differ from deep ones in many aspects of nutrient dynamics, biotic structure and interactions of various trophic levels. Though very common in European lowlands, shallow lakes attract inadequate attention from research teams. This book aims at filling gaps in our knowledge of the processes which take place in non-stratified lakes. It contains proceedings from the international conference `Shallow Lakes *95' held in Mikolajki, Poland, on 20-26 August 1995. In more than 50 original papers up-to-date views on eutrophication, degradation and recovery of shallow lakes are presented. The first four sections of the book (Nutrient fluxes, Biotic structure, Trophic interactions and Whole lake studies) deal with theoretical aspects of lake functioning while the fifth (Biomanipulation, restoration and management) is devoted to practical measures undertaken to improve water quality in shallow lakes. The book is therefore addressed to university biologists and ecologists and PhD students, as well as to managers involved in restoration of shallow lakes.
The most complete fly fishing guide to musky to date Musky, short for muskellunge, have been called the fish of 10,000 casts and are one of the most challenging, yet rewarding, fish to catch on a fly. Musky have a large range--from northern Michigan, northern Wisconsin, and northern Minnesota through the Great Lakes region, north into Canada, throughout most of the St. Lawrence River drainage and northward throughout the upper Mississippi valley, extending as far south as Chattanooga in the Tennessee River valley. This much-anticipated book is the most complete guide to fly fishing for musky to date and includes fly patterns, wisdom, and local techniques from top guides around the country: Blane Chocklett (Virginia); Brad Bohen (Wisconsin); Chris Willen (Tennessee), and more.
Pike and related fish form an important part of aquatic ecosystems and are also commercially very valuable. This title provides full coverage of the biology, ecology and exploitation of this important group of fish and will be invaluable for fisheries scientists, fish biologists, aquatic scientists, ecologists and environmental scientists.

Take your knowledge of fishes to the next level Fishes of the World, Fifth Edition is the only modern, phylogenetically based classification of the world’s fishes. The updated text offers new phylogenetic diagrams that clarify the relationships among fish groups, as well as cutting-edge global knowledge that brings this classic reference up to date. With this resource, you can classify orders, families, and genera of fishes, understand the connections among fish groups, organize fishes in their evolutionary context, and imagine new areas of research. To further assist your work, this text provides representative drawings, many of them new, for most families of fishes, allowing you to make ...
