“…However, according to an agreed arrangement, the Soviet whaling fl eets had Japanese observers and vice versa. While the U.S.S.R.'s illegal whaling was revealed in 1994 (Yablokov, 1994), it took even longer to discover that some illegal catches and data falsifi cations continued on the Soviet fl eets despite implementation of the IOS.…”

“…The recent emergence of reliable data regarding the extent of illegal whaling conducted by the USSR between 1948 and 1979 has made clear how much poaching took place (Yablokov, 1994;Clapham and Ivashchenko, 2009;Ivashchenko et al, 2011Ivashchenko et al, , 2013. The estimate for the total global catch by the USSR is 534,204 whales, of which 178,811 were not reported to the IWC.…”

“…Similarly, the USSR is now known to have conducted large-scale illegal catches for more than three decades (Yablokov, 1994;Clapham and Ivashchenko, 2009;Ivashchenko et al, 2013;Ivashchenko and Clapham, 2014). On a much smaller scale, between 1951 and 1956 a factory ship registered in Panama, the Olympic Challenger, owned by Aristotle Onassis' Olympic Whaling Company, was consistently "shooting anything that swam and at any time" (Elliot, 1997).…”

“…It was recently reported that the Soviet Union conducted large-scale illegal whaling operations, including for protected species (see Yablokov 1994, Zemsky et al 1995. Although the majority of this activlty occurred in the Antarctic, extensive illegal catches were also made in the northern hemisphere.…”

The population identity of humpback whales Megaptera novaeangliae in the Arabian Sea has long been a matter of dispute New information is presented from this region, based upon whaling and obsel-vat~ons conducted by the Sov~et Union, primarily in November 1966. In that month, a total of 238 humpbacks were killed off the coasts of Oman, Pak~stan and northwestern India; 4 others were killed in 1965. Biological exannnat~on of these whales showed that they differed s~gn~flcantly from Antarctic humpbacks in terms of size, coloration, body scars and pathology. In a d d i t~o n , analysis of the length distribution of 38 foetuses indicates that the reproductive cycle of the Arabian Sea whales was unequivocally that of a northern hemisphere population. Mean lengths were 12.8 m for males (range: 9.5 to 14.9 m, n = 126) and 13.3 m for females (range: 9.5 to 15.2 m, n = 112). All whales 12.5 m or more in length were sexually mature. Among 97 females examined. 12 (12.4":21 were immature. Of the 85 mature females, 39 (45.9%)) were pregnant, 3 (3.5%) were lactating, and 43 (50.6%) were resting. A more plaus~ble pregnancy rate, adjusted for underrepresentation of lactating females, was estimated at 39%). A malority of stomachs examined contained food, including euphausiids and fish. Overall, the data presented here argue strongly that Arabian Sea humpbacks constitute a discrete population which remains in tropical waters year-round, a situation which is unique for this specles.
