The global blue whale population is estimated to be 5,000–15,000 mature individuals and 10,000–25,000 total as of 2018. By comparison, there were at least 140,000 mature whales in 1926. There are an estimated total of 1,000–3,000 whales in the North Atlantic, 3,000–5,000 in the North Pacific, and 5,000–8,000 in the Antarctic.
Prewhaling population may be a huge under-estimate. A recent study (2003) gives population estimates for fin and humpback whales far greater than those previously calculated for prewhaling populations. Similar studies have not yet been done for Blue Whales. (Roman, J and S.R. Palumbi. 2003. Whales Before Whaling in the North Atlantic.
The decline of global whale populations Blue whale populations have declined dramatically due to unregulated commercial whaling, putting them at risk of extinction.. Prior to the setting up of the IWC in 1946, unregulated whaling had depleted a number of whale populations to a significant extent, and several whales species were severely endangered.

The fin whale (Balaenoptera physalus), also known as the finback whale or common rorqual, is a species of baleen whale and the second-longest cetacean after the blue whale. The biggest individual reportedly measured 26 m (85 ft) in length, with a maximum recorded weight of 77 to 81 tonnes (85 to 89 short tons ; 76 to 80 long tons ).

In 2023, paleontologists estimated that the extinct whale Perucetus, discovered in Peru, may have outweighed the blue whale, with a mass of 85 to 340 t (94–375 short tons; 84–335 long tons). [18] However, more recent studies suggest this whale was much smaller than previous estimates putting its weight at 60 to 113 tonnes. [19]
