Pods of orcas are stalking the boats of Alaska fishermen and stealing their halibut catches, leaving the men with no fish and thousands of gallons of fuel wasted trying to flee.
It’s not exactly new that orcas, also called killer whales, can learn to recognize boats and then steal their catches. One article from the Journal of Marine Science traces the habit back to at least the 1960s, and complaints by Japanese fishermen. Now, though, the problem seems to be getting worse. The killer whales are tailing boats all around Alaska, with the majority of the pack seemingly in the strip of water between Russia and Alaska, called the Bering Sea.
One fisherman, Robert Hanson, complained that he lost 12,000 pounds of halibut to whales, and 4,000 gallons of fuel getting away. (Given that one 2014 study said that such thieves could cost boats up to $500 a day, these recent examples seem more serious.) He told of how a pod tracked him for 30 miles and then stayed in the area with him for 18 hours. Dark.
Another one said that sometimes the killer whales will take all of the catch — as much as 30,000 pounds in a day — and leave only the halibut “lips” still attached. Really dark.
