Trends in regional estimates of illegal fishing, averaged over 5 year periods 1980–2003.

<p>The figure given is the mid-point between the lower and upper estimates of illegal and unreported catch in the case study species, expressed as a percentage of reported catch of case study species.</p

Summary of regional estimates of illegal fishing, averaged over 2000–2003.

<p>Summary of regional estimates of illegal fishing, averaged over 2000–2003.</p

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; <i>23</i>).

<p>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.</p

Illegal and unreported catch, expressed as a percentage of reported catch, by species group 2000–2003.
