10 gives original and present estimates for the stocks of whales, a large proportion of which frequent Antarctic waters. This decline in stocks occurred in spite of the efforts of the International Whaling Commission (IWC) to regulate the whaling industry. A century ago the initial numbers of baleen whales feeding on Antarctic waters totalled about one million with a biomass of about 43 million metric tons. By the 1930s the population was reduced to about 340,000. The current biomass is about onesixth of the initial stock or about 7 million tons.

1 Introduction During recent years there has been a steady increase in the total world fish catch (including shellfish) to a plateau, reached in the early 1970s, of about 70 million tonnes per annum. Estimates of the total world potential of marine living resources of the conventional type indicate that the maximal sustainable catch is probably in the order of about 100 million tonnes. However, many of the remaining unexploited or relatively unexploited resources comprise species which are less attractive because of their low value, accessibility, etc.

During the breeding season there may be very high local predation of krill as the foraging birds do not spend more than 20 hours travelling between their nesting sites and feeding grounds. Seals Early sealing expeditions to Antarctic waters concentrated primarily on the Southern Fur Seal (Arctocephalus gasella) and the Southern Elephant Seal (Mirounga leonina). Both species were almost exterminated but both have recovered somewhat. 7 (Everson, 1977). The total stocks of this species in the Southern Ocean are estimated at about 363,000 ACMRR, 1977).
