The Japanese stern trawler Chiyo maru No. 5 conducted krill fishing operations in CCAMLR Subarea 48.1 during February, 2000. Under an agreement by the Japanese and United States governments, a CCAMLR International Scientific Observer was present on the vessel. This paper presents much of the information collected in graphical form, and serves as a compliment to the Final Report of Scientific Observations submitted by the scientific observer (Rain, 2000). Fishing operations were conducted off the South Shetlands Islands north of Elephant Island and the lower South Shetlands Islands. Information on length frequency, maturity, and feeding intensity were summarized based on 5 regions off the South Shetland Islands where hauls were clustered. The biological information collected during this commercial fishing operation agrees well with the findings of the CCAMLR 2000 synoptic survey within Subarea 48.1.
