Estimating the Worldwide Extent of Illegal Fishing
Figure 2
Relationship between the amount of illegal fishing (expressed as a proportion of the reported catch that is additionally taken as illegal and unreported catch) and an average of four World Bank indices of governance (Government Effectiveness, Regulatory Quality, Rule of Law and Control of Corruption, measured in 2003; 23).
Although there is a significant linear relationship between governance and the proportion of IU, the log-linear relationship shown above is a better fit to the data and has R2 = 0.4081, p<0.001 with 53 degrees of freedom. The broken lines are 95% confidence intervals.
