The study, published in Frontiers in Ecology and Environment, tracked fishing vessels through a common onboard technology, Automatic Identification System, that regularly transmits data as a way of preventing collisions. By tracking the boats, researchers found fishing vessels that complied with a one-year fishing ban maintained their catch levels by moving to other areas.

In addition to supporting more permanent protection in the Adriatic, the results hold promise for other highly exploited areas around the world where enforcement is challenging.
