Review evaluates conservation limit reference points for marine megafauna bycatch, highlighting quantitative frameworks to manage data-limited populations sustainably.

Key Points

To evaluate limit reference point estimators for marine megafauna bycatch and synthesize best practices for managing data-limited non-target populations.
Reviewed mathematical limit reference point estimators based on bycatch mortality data, abundance estimates, and life history parameters.
Assessed methodologies for incorporating statistical uncertainty and management risk tolerance using simulation-based frameworks like management strategy evaluation.
Found that estimators rely on shared core structures requiring vital rates and abundance, with abundance being the primary limiting factor for widespread use.
Identified two main methods for handling uncertainty: embedding risk tolerance directly into the reference point estimator or using probability distributions across bycatch estimates.
Determined that simulation testing is necessary to mitigate estimation bias and address technical, operational, and political hurdles in bycatch management.
