Global patterns in country-level slavery and fisheries catch and value. Maps show a percentage of unreported catch, b mean landed catch value per kg, and c national prevalence of slavery, colour-coded by country. Scatterplots show relationship between country-level slavery prevalence and individual fisheries variables for the 20 largest fishing countries: d prevalence of slavery per thousand people (Slavery/1000) vs unreported catch (% Unreported catch), e prevalence of slavery vs mean landed value (Landed value $/kg), and f observed against predicted values for a combined model, with selected European, Asian and South American countries labelled. Regression model R² values and F-test p values are labelled on scatterplots
