With further application of the ecosystem approach the CCAMLR has developed a mechanism to disperse the fishing effort once a trigger level is reached in order to avoid concentration of fishing in easily accessible areas or other negative effects on local populations of marine animals. Under Conservation measure 51-01 (CCAMLR 2008) in area 48, the Antarctic Peninsula, once a trigger level of 620 000 tones is reached the catch must be dispersed into smaller scale units. For the other side of the continent, in area 58.4.1, the catch of krill was set under the KLM to 440 OOOt and split into an eastern and western division until further scientific measures are to hand.
