Modern acoustic instruments, sophisticated displays and microprocessor-based signal processing are in constant use throughout the world to map the distribution of fish, estimate biomass, locate fish shoals, monitor fish movement and study fish behaviour. The use of underwater sound in this way is hence an extremely important tool for the study of fish for research purposes and in commercial fisheries. "Fisheries Acoustics" provides coverage of the subject, with particular emphasis on practical acoustic methods for fish stock assessment. The authors of this book, who are both widely experienced in the use of acoustics and the interpretation of related data, cover the underlying principles and current applications in fisheries research and outline the advantages and limitations of acoustic methods. The book includes important information relating to the practical problems of survey design, execution and interpretation and this is illustrated using examples drawn from acoustic surveys on commercially important fish species from many areas of the world.
"Fisheries Acoustics" is designed to serve as a reference work and manual for all concerned with fisheries research, is international in appeal and should be of interest to all students, research workers and professionals in fisheries research and fishing industries throughout the world.
