This record is an overview entry for biological data collected on Southern Surveyor cruise SS 03/92. This cruise took place in waters off the northeast and west coasts of Tasmania during 15 July - 13 August 1992, under the leadership of Tony Koslow. Biological data collected on this cruise include samples of orange roughy and blue grenadier including other fish, acoustic data and target strength measurements of the fish. Orange roughy eggs were sampled for buoyancy experiments and to determine the vertical distribution of eggs from 0-900 m depth. 9 samples of flesh, liver, gonads, and otoliths from 36 cm orange roughy at reproductive Stage IV were obtained to examine the relationship of body condition to fecundity. Blue grenadier eggs were also sampled to determine the vertical distribution of eggs from 0-600 m depth and for incubation experiments. CTD profiles were carried out during the cruise to determine sound velocity and absorption profiles. Please note: This metadata record is a preliminary entry derived from information in the cruise plan and/or cruise report. Individual data types - which may span several cruises - will be indexed separately within this metadata system in due course. - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.
