Major interest in the Antarctic’s marine living resources developed after the 1959 Antarctic Treaty. Species caught include krill (Euphausia superba), which has dominated the reported landings since early 1980s, rockcod (Notothenia rossii, Lepidonotothen squamifrons), icefish (Champsocephalus gunnari, Chaenodraco wilsoni) and toothfish (Dissostichus mawsoni).
The catch data from this LME are too crude for ecosystem indicators such as PPR, MTI or FiB index to be computed.
Marine Trophic Index and Fishing-in-Balance index:
Although based on partial catches the MTI shows a rapid and strong decline in the 1970s and 1980s, reflecting the transition in landings from fish (mainly rockcod) to krill, while the FiB index remains stable, suggesting that no geographic extension took place since the early 1970s.
Catch from bottom impacting gear:
The percentage of catch from the bottom gear type to the total catch reached its peaks at 70% in 1957 and 1963, respectively. Then, the percentage fluctuated around 1% in recent decade.
The total effective effort reached its peak at 12 million in 1979 and then fluctuated around 4 million in the recent few years.
