Project Description

This project will restore western Atlantic bluefin tuna by identifying and sharing fishing practices that reduce bycatch in the pelagic longline (PLL) fishery. This project will involve conducting a pilot study to better define an optimal PLL fishing depth to reduce bluefin tuna bycatch. Results from the pilot study will be shared with the PLL fishery. Anticipated benefits of identifying optimal depths in the PLL fishery include positive economic benefits to fishermen from increased target catch per unit effort and positive benefits to bluefin tuna stocks and possibly other bycatch species by reducing fishing mortality. The project will be adaptively managed throughout its ten-year timeframe from 2022 to 2031.
