Net Cameras Add New Dimension To Viewing Fish Behavior

The Advanced Survey Technologies group recently developed a camera and lighting system for observing fish behavior and the performance of the marine mammal excluder device (MMED) in the Nordic rope trawls used for surveys of coastal pelagic species (CPS). The cameras were deployed numerous times and provided hours of quality high-definition (HD) video footage of sardines, jack mackerel, squid and other small fishes and krill. Video of a sea lion being excluded from the trawl was also observed. Minor modifications are being made to this camera system for operational use during the upcoming 80-d west coast sardine/hake (SaKe) survey aboard the NOAA Ship Bell M. Shimada.
