Standard Methods for Sampling North American Freshwater Fishes

About this book

This is the second updated edition of an important, popular reference book that provides standard sampling methods recommended by the American Fisheries Society (AFS) for assessing and monitoring freshwater fishes in North America. Involves contributions from over 500 fisheries scientists from almost 200 agencies, universities, and nongovernmental organizations from Canada, Mexico, and the United States.

Methods apply to ponds, reservoirs, natural lakes, streams, and rivers containing cold and warm water fishes and, new to this edition, Great Lakes, cenotes, and wetlands. Rangewide and ecoregional averages for indices of abundance, population structure, and condition for almost 50 individual species are supplied to facilitate comparisons of standard data among populations and are much expanded for this edition. Provides information on converting nonstandard to standard data, statistical and database procedures for analyzing and storing standard data, methods to prevent transfer of invasive species while sampling, information on new techniques since the first edition such as environmental DNA sampling, and the latest methods to calibrate electrofishers.
