Overview: Fishing for C. gunnari began in Subarea 48.3 in the late 1970s, with large catches taken by Eastern European vessels. Catches peaked in 1983 at a reported 178,824 tonnes. Following concerns about the depletion of stocks, CCAMLR closed the fishery in the early 1990s. The fishery was reopened in 1995, but with a highly conservative catch limit, and was restricted to pelagic trawling to avoid impacts on non-target species. Conservation measures, including requirements to clean nets and ensure that they sink quickly, also reduced incidental mortality of birds. By-catch and incidental mortality is now low. Currently, the fishing activity in Subarea 48.3 focuses on an area to the northwest of South Georgia. Vessels use pelagic trawls with a minimum mesh size of 90mm. In recent years, the catch limit for this fishery has been between 1,500 and 5,000 tonnes, with up to four or five vessels operating.
