Acoustic Fish Reconnaissance provides providing an overview of the theoretical and practical aspects of acoustic search, detection, interpretation, and population estimation for commercial benefit.

Features:

• Examines the problem of sound scattering by commercial items
• Reviews how to determine characteristics of fish-finding devices and if they meet the user's demands
• Discusses the efficiency of detecting commercial fish concentration via acoustic instruments
• Explains the interpretation of species, size, and quantity based upon recordings of commercial item concentrations
• Considers aspects of acoustic surveys related to biological resources and fishing conditions
• Describes fisheries-acoustic surveys
• Conveys the importance of passing observations and surveys conducted on fishing vessels
