One factory ship of the USSR is known to have violated the Convention by killing an unspecified number of Right Whales around Tristan de Cunha in 1958. Apart from these lapses, the protective measures appear to have been successful inasmuch as some remnants have persisted into the 1980s in all oceans previously occupied. In addition, the species is listed on Appendix I of the Convention on International Trade in Endan- gered Species of Wild Flora and Fauna (CITES). Canadian whaling regulations under the Fisheries Act also prohibit the taking of whales in Canadian waters. Population Sizes and Trends The current status of global populations of Right Whales was reviewed and discussed at a symposium and workshop meeting sponsored by the IWC and held in Boston from 15 to 23 June 1983. There was common agreement on two points: i) the difficulty of accurately counting small populations of whales dispersed over wide geographical areas, and ii) the greater difficulty of estabishing any population dynamic or demographic trends even in more or less genetically isolated sub-stocks. There are data (Kraus and Prescott 1983; Winn et al. 1983) showing local movements of individual Right Whales over some hundreds of kilometers within a population spatial range, but no evidence for movements between populations. The 1983 working group recognized four discrete northern hemisphere stocks (NE and NW Pacific and Atl
