Summary

This study trialed the use of  on-demand, acoustic recovery systems/ on-demand gear (ODGs) as an alternative to vertical buoy lines (VBLs) to reduce North Atlantic right whale (Eubalaena glacialis) entanglement risk in commercial lobster and crap trap fisheries in offshore New England. Trials occurred between 2020 and 2023, and 5,798 hauls were completed using 10 different ODG prototypes. Recovery success of hauls increased throughout the trials as participants gained more experience with the gear, and fishers were able to use the gear to successfully access areas that prohibit VBLs.
