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.

In this edited work, international experts in fisheries management and ecology review and appraise the status of river fisheries, assessment methodology, constraints on development, issues and options regarding management and associated problems in both temperate and tropical countries. Recommendations are made to improve management and an attempt is made to provide guidelines for formulating policy, for planning methodology and for evaluating future activities. Assessment of fish community structure and dynamics. Factors constraining stock recruitment. Fish habitat requirements. Instream flow needs. Impact of water resource schemes. Rehabilitation of river fisheries. Enhancement of fish stocks. Exploitation of stocks. Management of migratory fish stocks. Conservation of endangered species. Integrated river management. Bioeconomic issues. Legislation. Multinational management of rivers. Case studies.

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.

The book envisages the use of under-water electric field for catching fish. The use of electricity for catching fish has been practiced from a long time by the fishermen of different regions, the recorded evidence of which goes to 1886, when one Mr. Isham Bagg was issued a patent in Britain for catching fish with electricity. The author is the first person, who undertook fishing with electric seine as early as 1962 in Odisha, and in 2015 by developing an electric fish catcher. Originally, after several studies on fish electrophysiology, in different countries, the technique was applied in freshwater fisheries, like, streams, rivers, lakes and reservoirs, mainly for research and investigations and fisheries management. In this book, the author has tried to compile the basic principles of electrofishing system, with reference to design, construction and field application with the precautions and safety measures to be followed while construction and use of the electrofishing gear not only for the operational crews, but also for the fishes to avoid unnecessary mortality and injuries. The experiments and trial of electrofishing in sea water, particularly, of pulse trawling for flat fish, Hovercran shrimp trawling, and experiments with pelagic fishes in design criteria for electrical fish harvesting systems, which includes netless fish harvesting and mid-water electric trawling have find place in the book. The principal system components of electric fishing machine, its design consideration, power transmission, both from battery operated backpack and boat mounted electrode array and the factors affecting the efficiency of electrical fishing gear have been taken into account in the book.

Based on a selection of papers presented at the International Symposium on the Ecological Basis for River Management in March 1993, it addresses the underlying ecological issues in the six major operational functions of river management: water quantity, water quality, management of the natural river environment, management of fish stocks and fisheries and catchment management.

Here fishing guide and fly designer Henry Cowen shares decades of hard-earned knowledge of stripers for the first time. Learn about the species, its food, and where and how to find them, so you can land far more and bigger stripers. Knowing where and how to find stripers is key, and Cowen offers proven techniques for locating fish in both reservoirs and rivers, including water temperature, seasonal patterns, weather patterns, locating the bait, water clarity, and wildlife and how it can help anglers. The popularity of fishing for striped bass in freshwater is growing quickly, especially as global warming allows the fish to live in waters that used to be too cold. This is the first major book on the subject, one that is sure to be part of a big trend among fly fishers. Cowen carefully outlines fishing tactics, along with detailed photographs of the steps involved, covering: Retrieving a striper Fishing a point, uphill and downhill Working a topwater fly (constant retrieve) Hooking a fish (strip strike) Fishing a hump Fishing a saddle or blow-through Fishing a breakwater Using the countdown method Fishing a deep hole in a river Fishing a creek in a river And much more! Cowen also takes a close look at freshwater striped bass, explaining how natural and stocked fisheries are managed as well as the difference between the various species. Along with help choosing equipment and some notes on wading tactics, anglers will have everything they need to improve their fishing techniques or make a start on this popular all-American outdoor sport.
