Costa Rican president Laura Chinchilla announced new, stricter tuna fishing rules during her opening remarks at the Fourth Global Fisheries Enforcement Training Workshop in Playa Herradura, on Costa Rica’s central Pacific coast, Monday.

In particular the new rules focus on the use of fish aggregating devices (FADs) which are illegal in Costa Rica, but some tuna fishing boats still use them in order to attract large schools of tuna, reported The Tico Times.

The new regulations require operators of fishing vessels to show proof that they are aware of Costa Rican laws banning the use of FADs.
