    A final report of scientific observations conducted aboard the Japanese krill fishing vessel Chiyo Maru No. 2 was presented to the first meeting of WG-EMM. The WG-EMM welcomed the report but noted that the results for reporting fish bycatch were not presented in CCAMLR's standard format. This manuscript presents a brief reanalysis of the bycatch data collected onboard the Chiyo Maru No. 2; means and variances are calculated according to the methods of Aitchison (1955) and Pennington (1983). In numbers, an average of about 20 fish were caught per ton of krill, and an average of about 23 fish were caught per hour of towing. In weight, an average of about 1.5 kg of fish were caught per ton of krill, and an average of about 2 kg of fish were caught per hour of towing. Confidence intervals for mean bycatch estimates are wide.
