Meta-analysis is used in our work to synthesize precise effect sizes, determine "Best Practices" for issues such as promoting post-release survival outcomes and bycatch mitigation, and if warranted, design future studies to a high level of power and precision.

Survival Studies


Accounting for components of fishing mortality, including post-release (Fr), and at-vessel mortality (Fc) is necessary for robust assessments of the effects of fishing.   We explore factors influencing mortality outcomes in an effort to increase survival of bycatch and other non-targeted animals.
