This record describes the datasets obtained on Courageous Cruise 020. The data were obtained from the Tasman Sea and Bass Strait in May 1977. Data were obtained from acoustic and trawl surveys of Jack mackerel (Trachurus declivis) and other demersal and pelagic fish. Length, weight and target signal strength were determined. Data on feeding preferences were also obtained. Additional information regarding this dataset is contained in the cruise summary for this voyage. Please note: this metadata record is a preliminary entry derived from information in the cruise summary. The present location and/or continued availability of the original data, specimens etc. has not been verified at this time. Please contact the Data Centre if further details are required.
