Using cormorants to catch fish has been a custom in China for the past 1,000 years. However, more modern fishing methods have resulted in a decline in this traditional method of fishing, and today there are only a handful of cormorant fishermen left, most of them in their 80’s. The fisherman train the cormorants to catch fish and give them special commands. On receiving a command to enter the river, the cormorant dives into the river and looks for fish. If it is dark, the light from the lantern assists them to see the fish.
