Comparative fishing to evaluate the viability of an aligned footgear designed to reduce seabed contact in northern shrimp bottom trawl fisheries

Abstract: Abstract:We developed and evaluated an innovative trawl technology that reduces seabed contact while targeting northern shrimp (Pandalus borealis) off the east coast of Canada. The innovative footgear, referred to as the "aligned footgear", was evaluated in a flume tank to estimate contact area with the seabed and then tested at sea for engineering performance and catchability. Results demonstrated that the aligned footgear trawl produced a substantial reduction (i.e., 61%) in the predicted contact area with t… Show more

“…Comprising three case studies situated on Canada's Atlantic and Pacific coasts and in Quebec, it bridged geographic and linguistic divides to bring together groups that probably never would have overlapped if not for the CFRN. Novel trawl designs, including footgear and a gear monitoring system, were devised and tested in trawl simulations (flume tank) and at sea on Newfoundland and Labrador northern shrimp trawlers (Winger et al 2018). Habitat suitability models were also developed to predict benthic species assemblages and distribution and the potential impacts of fishing gear over time, with application to Marine Protected Area planning and ecocertification.…”
