Trapped by Uncertainty? A Decision Framework for Evaluating Escapement-Based Management Procedures for the Spot Prawn (Pandalus platyceros) Fishery in Howe Sound, BC.

摘要

Fisheries and Oceans Canada (DFO) recently adopted the precautionary approach (PA) to fishery management that aims to ensure resource sustainability by demonstrating the application of reference points and formal decision rules. DFO and the Pacific Prawn Fishermen Association are interested in evaluating the current prawn management strategy in Howe Sound, BC, under PA requirements. This study identifies and evaluates the main components of the prawn fishery management strategy that influence the prawn population in Howe Sound, BC. Then, uses a closed-loop simulation feedback control system, management strategy evaluation, to evaluate the performance of management options in the presence of uncertainty. Results from these evaluations highlight the tradeoffs and help identify the best options for mutual ecological and economic gain for the Howe Sound prawn fishery.
