Description
Acoustic surveys are generally carried out on spawning and pre-spawning aggregations of fish. more

Acoustic surveys are generally carried out on spawning and pre-spawning aggregations of fish. Outside of the spawning season many pelagic species are generally very scattered over a large geographical area and difficult to detect using acoustic methods. A cruise track is first formulated with data from previous surveys, commercial catch data and the help of the fishermen and fishing industry. This is the spatial dataset of the Acoustic pinger transects.
