Insecure fisheries: How illegal, unreported, and unregulated fishing affects piracy.

We examine greed and grievance mechanisms that connect illegal, unreported, and unregulated (IUU) fishing and piracy. We use several cases (e.g. Somalia, Nigeria) to illustrate these mechanisms and empirically examine the relationship between IUU fishing and state-year piracy events from 1990 to 2015. We find that countries experiencing significant levels of IUU fishing face much greater risks for piracy. We also evaluate several mediating conditions of our theory with interaction terms (state capacity, state fragility, and legal fishing incentives) and find that the relationship between IUU fishing and piracy is strongest for moderately developed states with greater state fragility and higher fish catch values.
