When was there a ban for hunting sea otters fur?

The ban on hunting sea otters for their fur took place in 1911 with the signing of the International Fur Seal Treaty. This treaty, also known as the North Pacific Fur Seal Convention, was signed by the United States, Russia, Japan, and the United Kingdom. It aimed to address the overhunting of fur seals and sea otters in the North Pacific region. The ban on sea otter hunting was part of conservation efforts to protect these species from further depletion due to excessive harvesting for their valuable fur.

I hope that this helps!
