This record is an overview entry for biological data collected on Southern Surveyor cruise SS 05/93. This cruise took place in waters east of Bass Strait and off the east, west and southern Tasmanian coasts during 14 July - 25 August 1993, under the leadership of Tony Koslow, Sebastian Rainer and Barry Bruce. Biological data collected on this cruise include photographic and dredge samples of several relatively unfished hills to examine the benthic habitat associated with the orange roughy and oreo dory fishery. Zooplankton and mid-water nekton samples. Extensive biological and distribution data on a wide range of demersal fish species, including SEF quota species. Stomach contents from SEF quota and other abundant fish species were sampled to determine their immediate feeding links and to compare with stable isotope analysis. Samples of fish, plankton and seafloor invertebrates were obtained for stable isotope analysis to provide preliminary data on their position in the community food web. Benthic and epibenthic samples to determine the appropriate intensity and spatial scale for experimental field studies on the effects of trawling on seafloor communities. Video photography of fish behaviour at the mouth of the trawl net. Acoustic data including data from St Helens Hill area to estimate the biomass of orange roughy. Specimens of SEF quota and other species for collaborative studies in other Australian research institutions. Blue grenadier egg and larval samples to assist in planning a future survey of blue grenadier biomass. 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.
