A tool to estimate the contribution of fishing gear modifications to reduce benthic impact by Szostek, Claire Louise, Hiddink, Jan Geert, Sciberras, Marija, Shepperson, Jennifer L., Thompson, Stephen, Hormbrey, Samantha, Caveen, Alex, Lart, William, Rodmell, Dale, Kaiser, Michel J.

“…The ecological effects of seabed‐penetrating fishing gears depend, in part, on the seabed penetration (P) of the gear. We present a gear impact tool that…”

The Development of a Spatially Dynamic Model to Evaluate Management Scenarios in a Scallop Fishery by Shepperson, Jennifer Louise

“…Fisher behaviour remains a key source of uncertainty in fisheries management. Failing to account for the behavioural response of fishers can lead to unexpected…”
