I am wondering when the Nuu-Chah-Nulth stopped whaling.
I've been looking around and can't seem to find anything.
Gray whales were plentiful before “Yankee whalers” decimated the stocks, says Coté. In 1937, the US banned gray whale hunting and in 1972, the gray whale was placed on the endangered species list.

Whaling halted in 1972; however as the article makes clear, whaling started again in the 21st century when the population recovered, then halted again. There is no simple answer.
