Sustainable exploitation of small pelagic fish stocks challenged by environmental and ecosystem changes: a review
Small pelagic fish contribute up to 50% of the total landing of marine species. They are most
abundant in upwelling areas and contribute to food security. Exploited stocks of these …

Underwater acoustics in marine fisheries and fisheries research
OA Misund - Reviews in Fish Biology and Fisheries, 1997 - Springer
Underwater acoustics enables the detection and precise location of fish and is therefore a
prerequisite for effective fishing methods such as pelagic trawling and purse seining. The …

Species identification of pelagic fish schools on the South African continental shelf using acoustic descriptors and ancillary information
Stock assessment of exploited pelagic species often relies on hydroacoustic surveys, but a
major limitation of this approach stems from an inability to distinguish between the echoes of …
