Fig. 2: Temporal trends in effort and violations data, and detectability (as estimated by the model).
From: Improving detectability of illegal fishing activities across supply chains

The graph illustrates the changes in enforcement effort (blue), violations (orange), and detectability (green; scale on the right axis) over time. Effort and violations are represented on a logarithmic scale to accommodate the wide range of values observed in the dataset, with values ranging between 0 and 10. Detectability is measured using a separate scale on the right axis due to differences in units.
