Fisheries acoustics – Fisheries acoustics includes a range of research and practical application topics using acoustical devices as sensors in aquatic environments. Acoustic tag – An acoustic tag is a small sound-emitting device that allows the detection and/or remote tracking of fish in three dimensions.
Acoustic survey in fishing is one of the research methods that can detect the abundance of target species using acoustic detectors. For example, many pelagic fisheries are generally very scattered over a broad ocean and difficult to detect. Hence survey vessel with acoustic detector emits sound waves to estimate the density of plankton and fish ...
