Red List Status

The cause of the population reduction in Fin Whales (commercial whaling) that occurred in the 20th century is reversible, understood, and has been brought under control. For this reason, the species is assessed under IUCN Red List criterion A1, not under A2, A3, or A4. The current global population size is uncertain due to lack of data from major parts of the range, especially from mid-latitudes in the Southern Hemisphere. Therefore, rigorous evaluation against the criteria is not possible. However, plausible projections of the global mature population size indicate that it has probably recovered to over 30% of the level of three generations ago (1940) (i.e., reduction of
