Soviet fleets take protected whales and file false returns
From 1948 the USSR conducts illegal whaling worldwide, with fleets maintaining a falsified catch return for the International Whaling Commission and a true record internally. Blue whales are taken after they are protected. The reconstructed totals are large - about 330,000 whales killed in the Southern Ocean against roughly 185,000 reported - and the blue whale component is given differently across accounts, from one or two thousand up to more than three thousand. The consequence for science is that the twentieth-century catch series, the basis for every population reconstruction, was wrong while it was being used.

Soviet illegal whaling: the devil and the details
The USSR conducted illegal whaling from 1948, fleets keeping a falsified return for the IWC alongside a true internal record; Yablokov published the first account of the real scale in 1994, indicating roughly 330,000 whales killed in the Southern Ocean against about 185,000 reported. Protected blue whales were taken; the reconstructed number is given inconsistently across accounts, from one or two thousand to more than three thousand. V55 verification basis: retrieved in search summary attributed to this literature; no catch-data paper was fetched and no single blue whale total is asserted.
