Summary: | Implementation of precautionary approach (PA) management systems has generally proven to be a betterment over historic management practices in sustainable use of fisheries resources. However, PA management systems can minimize the application of holistic assessment advice. Single-indicator approaches, typically featuring a measure of stock biomass or abundance, have emerged as dominant in developing methods for PA frameworks. This often leads to advice generated from these frameworks being applied within narrowly focused decision-making pathways and can minimize management application of important ancillary factors. We argue this outcome is counter to the intent of PA management systems and that multi-indicator PA frameworks are a better approach. In this analysis, we detail the multi-indicator PA system development for demonstrative case studies focused on three lucrative fisheries resources in Newfoundland & Labrador, highlighting how multi-indicator PAs are potentially a better approach for the management of stocks with a contrasting range of ecological roles, socioeconomic importance, and data quality. The work is intended to generate a discussion on how PA frameworks should evolve to best suit management purposes. |
