When people build cities and introduce invasive creatures, resident critter populations sometimes adapt

Only a small fraction of the world’s fisheries—roughly 2 percent—are currently monitored by observers, meaning the vast majority of fishing activity, including the bycatch of protected species, happens without oversight.

Could Artificial Intelligence Make It Easier and Safer to Monitor Fisheries?

New A.I. analysis systems aim to count fish and identify species, streamlining the time-intensive process of recording commercial fishing activity
