Fishery life cycleThis fishery started in 1961/2.

Overview: The commercial fishery for Antarctic krill (Euphausia superba) was initiated in 1961/62 when 47 tonnes were taken by two research vessels from the USSR. During the following decade, small catches of krill were reported by the USSR as part of the research phase of the fishery development. A multivessel multination fishery for krill was active by the early to mid-1970s.

  • Aquatic species-related measures
    The limits on the fishery for krill in Area 48 is 620 000 t (CCAMLR FISHERY REPORT). The same provisions apply for the fishery for krill in Divisions 58.4.1 and 58.4.2, with the exception of the catch limits that are specified in Conservation Measures 51-02 and 51-03.
Status and Trends
Type of Fishery: Established. The history of catches in the krill fishery (Fig. 2) shows the initial increase in catches followed by a sudden decrease in 1983 and 1984, associated with technical difficulties in the fishery (Budzinski et al., 1985) and/or with an ecosystem anomaly that also impacted the reproductive performance of krill predators at South Georgia in 1984 (Priddle et al., 1988). The large drop in catches from 1992 to 1993 reflects the redeployment of the eastern bloc far-seas fisheries fleet following the dissolution of the USSR. The increase in catches since 2010 is largely driven by catches by Norway, and, the catch in Area 48 in 2020 was the largest catch reported from that Area.
