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.

This record describes the datasets obtained on Courageous Cruise 011. The data were obtained from waters in the Bass Strait, and in waters off the coasts of northeast Tasmania, Victoria and New South Wales in August and September 1976. Data were obtained from acoustic and trawl surveys of Jack mackerel (Trachurus declivis) and other demersal and pelagic fish. Year class, length and gonad stage were determined.

This record describes the datasets obtained on Courageous Cruise 018. The data were obtained from the Tasman Sea and Bass Strait in March 1977. Data were obtained from acoustic and trawl surveys of Jack mackerel (Trachurus declivis) and other demersal and pelagic fish including Trachurus mccullochi. Length and weight were determined. Levels of parasitic infestation were also noted on a routine basis from all catches. Hydrological sampling of an oceanic eddy off the NSW coast was also carried out.
