Up to 1 in 5 fish taken from the sea is caught illegally, costing as much as $23.5 billion globally each year. This illegal fishing harms ocean health and law-abiding fishers whose livelihoods depend on fish—and is often indicative of the presence of other transnational crimes. But with sophisticated technology and international cooperation, as well as greater industry engagement, we can help deter these crimes on our oceans. Host Dan LeDuc talks with Peter Horn, who leads Pew’s work from London with Oversea Ocean Monitor—satellite technology that helps countries detect illegal fishing. We also hear from Sandy Davies of Stop Illegal Fishing, who works with FISH-i Africa, a network of African nations committed to ending illegal fishing. To learn more, visit pewtrusts.org/afterthefact.
