Overall Objective:
To summarise and integrate existing data to estimate cryptic mortality of seabirds in trawls using standard mitigation estimates should explicitly contain uncertainty, and be specific to the capture method and fishery groups identified under project PRO2019-10.
Specific Objectives:
1. Summarise existing data to assign priors for various parameters within a simple transition matrix model to estimate cryptic mortality of seabirds in trawls using standard mitigation, including rates of: live release survival; death by drowning in the net; death by warp strike; as well as rates of body retention vs. body non-retention in the net.
2. Construct a simple Bayesian model combining the parameter estimates from Objective 1, and fit to available data (e.g., pre- vs. post-tori line warp strike rates; results of autopsies; injury reporting codes; capture method) to estimate cryptic mortality
