Fig. 6: Vessel behavior related to Port State Measures Agreement (PSMA) entry into force and port duration.
From: Revealing global risks of labor abuse and illegal, unreported, and unregulated fishing
(a) Relative changes in the number of visits by foreign vessels to PSMA parties by flag group for fishing vessels between 2015 (pre-PSMA) and 2017 (post entry into force). Points are medians of Bayesian posteriors, and thin and thick horizontal lines are 95% and 50% credible intervals (CIs), respectively. Vertical line at 0 indicates no change. Black points indicate 95% CIs that do not overlap with zero, gray points indicate 50% CIs do not overlap with zero, and white points indicate overlap. (b) Port stop duration by flag group for fishing vessels, using gear type and port state as random effects. Points and horizontal lines represent the best estimates and 95% confidence intervals, respectively. See Fig. 3 for flag group descriptions and Supplementary Table 2 for countries associated with different flag groups.
