What was the population of humpback whales in 1900?

In 1900, the population of humpback whales was significantly reduced due to extensive whaling practices, with estimates suggesting that only a few thousand individuals remained. Prior to the whaling era, their numbers were likely in the hundreds of thousands. Conservation efforts and whaling bans in the latter half of the 20th century have since allowed populations to recover, but precise historical figures from that time are difficult to ascertain.
