Summary
Four species of fish (Notothenia squamifrons, N. rossii, Dissostichus eleginoides and Champsocephalus gunnari) have been or are exploited in the shelf zone of Kerguelen Islands and the Skif Bank since 1970. However, detailed records of the fishery date from 1980. Following the declaration of the exclusive economic zone in 1978, the fishery has been carefully controlled since stocks of N. rossii and N. squamifrons were shown to be severely depleted. This paper reviews the catch and fishing effort for the calendar years 1970 to 1978 and for the split years 1980/81 to 1987/88, and presents results on the changes in the demographic structures and the population abundance. These results were derived from virtual population analyses and catch per unit effort. The two methods although completely independent from each other, both show similar trends in the populations. A model utilising data up to 1987 was used to predict future fluctuations of the populations given different levels of fishing activity.
