Marine mammal interactions with trawl gear

Underwater video technology was used to observe marine mammal interactions (seals, in particular Australian fur seals) within midwater trawl nets.


A camera system was placed inside the trawl net in the vicinity of a Seal Excluder Device, designed to prevent megafauna from entering the codend of the net and provide an escape point.


Digital video data was described according to a range of operational, catch and interaction fields, and made time-specific to each trawl shot. Data is linked to commercial catch and effort data providing operational, environmental and catch information.
