Development of quantitative tools for predicting protected species and fishery co-occurrence

Metadata Updated: March 7, 2016

Nearly all marine fisheries have at least some bycatch, which concerns commercial and recreational fishermen, resource managers, conservationists, and the public. High bycatch rates reduce the efficiency and sustainability of fisheries, but even extremely low bycatch rates can be a problem for protected or rebuilding species. Spatial fishing practices affect bycatch rates, and understanding spatiotemporal patterns in bycatch offers a possibility to improve fisheries management. We demonstrate the ability of powerful new tools, integrated nested Laplace approximations (INLA) and stochastic partial differential equations (SPDE), to spatially model bycatch in two large U.S. fisheries observer datasets (West Coast Groundfish and Hawaii Longline Observer Programs). We plan to produce spatial bycatch prediction maps to help management reduce bycatch.
