A simple approach for calculating the potential yield of krill from biomass survey results
calculations is that the probability that the kri11 spawning biomass drops below 20% of its average pre ... -exploitation level over a 20 year period of harvesting should not exceed l0%. The value of λ depends strongly ...

THE ASAM 2010 ASSESSMENT OF KRILL BIOMASS FOR AREA 48 FROM THE SCOTIA SEA CCAMLR 2000 SYNOPTIC SURVEY
Abstract: In June 2010 the CCAMLR ASAM working group examined the acoustic methodology applied to the CCAMLR 2000 synoptic survey data to generate a quality checked krill biomass for area 48 following the acoustic protocol identified in ASAM 2009. The total biomass of krill in the Scotia Sea was

Educational poster on hook ingestion
Abstract: Since the 2001/2002 season CCAMLR has recognised the importance of the high level of hooks discarded in fish heads which ingestion by seabirds, especially wandering albatrosses which are large enough to swallow fish heads whole (SC-CAMLRR-XXI/BG/7). For example, in 2001/02 the scientific
