Figure 1.

Estimated mean daily standardized fishing effort (as the number of sonar device users) per administrative unit during weekdays and weekends by country, shown for each study period (pre-lockdown, during lockdown 1, post-lockdown 1, during lockdown 2, post-lockdown 2). The effort was estimated for each country's average administrative unit size after accounting for variation due to season, year and the uptake of the device. The effort is scaled to the weekday of the pre-lockdown stage, which is therefore set to 1 (shown as a dashed horizontal line). For effort predictions across all administrative unit population sizes, see electronic supplementary material, figure S9. The error bars represent 95% confidence intervals from the general linear mixed effect model predictions. Note that visualization of single fixed effects in mixed effect models does not reveal the full effect size, since a lot of variation is explained by random and other fixed effects. Therefore, fixed effect significance should not be assessed from this figure, but from model outputs presented in table 2.
