The comprehensive instructional and reference volume on fisheries sampling and analysis techniques. This new edition describes the techniques and approaches used to collect and analyze fisheries samples and data, with a greater emphasis on quantitative techniques and estuarine and marine systems. Most chapters have been rewritten and all have been updated to include recent technological, analytical, and philosophical advances. A comprehensive glossary of terms is included. The book is intended for practicing fisheries professionals, researchers, professors, and advanced undergraduate and graduate students. eng
