Aimed at anybody that uses electro-fishing such as river keepers, members of rivers trusts, Environment Agency staff or anyone involved in the assessment of fish in rivers and is intended primarily for users of equipment in Great Britain and Republic of Ireland. To help users of electric-fishing equipment improve their understanding of the theory and practice of this important fisheries management tool, Bill Beaumont, from the Game & Wildlife Conservation Trust and an acknowledged world authority on this activity, has produced a unique 95 page operators manual, which gives clearly explained information on both the theory and practice of using the method.

This book is written to serve as a general reference for biologists and resource managers with relatively little statistical training. It focuses on both basic concepts and practical applications to provide professionals with the tools needed to assess monitoring methods that can detect trends in populations. It combines classical finite population sampling designs with population enumeration procedures in a unified approach for obtaining abundance estimates for species of interest. The statistical information is presented in practical, easy-to-understand terminology. - Presented in practical, easy-to-understand terminology - Serves as a general reference for biologists and resource managers - Provides the tools needed to detect trends in populations - Introduces a unified approach for obtaining abundance estimates

Electricity in Fish Research and Management, 2nd Edition provides a comprehensive discussion of the uses of both electricity and electrical principles in fishery management and research. It covers electric fishing (including theory, equipment, data analysis and practical factors affecting efficiency), fish barriers, fish counters and fish welfare issues. The book concentrates on Electric Fishing (or Electrofishing); an internationally accepted and widely used procedure for sampling fish. Over the past 50 years electric fishing has become a standard method for fishery studies and management e.g. establishing population densities and abundance. However, due to the potential hazards of the method (both to operators and fish) there is a continuing need to develop and promote best practice guidelines. The author has studied fish ecology for 40 years and understands the need for information that reaches out to all levels of understanding in the field. Previous books on this subject have either been collections of scientific papers and/or technical reports or very simple instruction manuals. In this book theory and practice is explained using non-technical language and simple equations. It brings depth as well as breadth in both information and principles behind the methods and should be an invaluable tool to both fisheries managers and researchers. Although the book is aimed at undergraduates, the clear explanation of the factors means that the book is suitable for all levels of practitioners.

Actor and passionate fisherman Robson Green is on a mission to discover the weird, the wonderful and the way-off-limits that the angling world has to offer. Working alongside some of the finest in their field, his exhilarating adventure series Extreme Fishing with Robson Greentakes him to the greatest fishing destinations ever seen; chasing the most elusive and terrifying creatures on the planet, learning new tricks, hearing old stories and eating pretty much everything he catches. From ice fishing in Siberia, mining eggs on the side of an active volcano in Papua New Guinea and struggling with the Mekong Giant Catfish in Thailand, to surviving a Force 10 hurricane on a Canadian trawler, catching a thirty-pound King Salmon in Patagonia and dancing the Salsa in Havana, this is an extraordinary modern-day fishing odyssey with tales of victory, defeat, struggle and joy. Complete with exclusive off-camera capers, top locations and best and worst catches, this laugh-out-loud adventure is jam-packed full of facts, fishing tips and, most importantly, fun.

Methods in Stream Ecology, Second Edition, provides a complete series of field and laboratory protocols in stream ecology that are ideal for teaching or conducting research. This updated edition reflects recent advances in the technology associated with ecological assessment of streams, including remote sensing. In addition, the relationship between stream flow and alluviation has been added, and a new chapter on riparian zones is also included. The book features exercises in each chapter; detailed instructions, illustrations, formulae, and data sheets for in-field research for students; and taxanomic keys to common stream invertebrates and algae. With a student-friendly price, this book is key for all students and researchers in stream and freshwater ecology, freshwater biology, marine ecology, and river ecology. This text is also supportive as a supplementary text for courses in watershed ecology/science, hydrology, fluvial geomorphology, and landscape ecology. - Exercises in each chapter - Detailed instructions, illustrations, formulae, and data sheets for in-field research for students - Taxanomic keys to common stream invertebrates and algae - Link from Chapter 22: FISH COMMUNITY COMPOSITION to an interactive program for assessing and modeling fish numbers

This beautifully illustrated and scholarly book examines the importance of electric fishes in science and medicine and how three species in particular shaped neurophysiology. Anchored in the philosophy and science of past epochs, it is the story of one of Nature's greatest puzzles. Over a long and tortuous path, it focuses on how some numbing fishes helped to make physiology modern.
