For this study, the researchers examined 22 billion data points of tracking data from fishing vessels that had been analyzed using machine learning technology.

"Advanced machine learning techniques allow us to identify fishing behavior without needing an analyst to look at the tracks of every single vessel," said co-author David Kroodsma of Global Fishing Watch, the organization visualizing and openly sharing in near-real time the global fishing data used in this research. "It would take an analyst years, if not decades, to make the same number of judgements about vessel behavior."
