The influence of towing speed and fish density on the behaviour of haddock in a trawl cod-end

In this study underwater video footage from cameras placed inside and outside the cod-end was analysed to provide a quantitative description of haddock behaviour inside the cod-end of a commercial whitefish trawl. The behaviour was quantified in terms of orientation, swimming activity, and duration...
