A hydroacoustic survey of Antarctic krill populations in CCAMLR Division 58.4.1

The survey design for an integrated biological/physical survey of Division 58.4.1 during January - March 1996 is presented in this paper. Key measurements to be taken during this survey include hydroacoustic determinations of krill distribution and abundance and physical oceanographic sampling along 18 regularly spaced transects from the Antarctic coastline to a distance of 180 n miles. The data on krill distribution and abundance will be submitted to CCAMLR for the purpose of setting a precautionary catch limit on the krill fishery in Division 58.4.1.
