This record describes the longline and trap data collected as part of the Tasmanian Seamounts Study undertaken by CSIRO Division of Fisheries in January 1997. Droplines and traps were deployed for between 2 and 7 hours at four seamounts to sample the motile fauna (fish, crustaceans, etc.) living within the benthic environment. 8 fish species were collected by these methods, the most numerous being squalid sharks (Etmopterus spp.) and eels (Diastobranchus capensis, Simenchelys parasiticus). The data from these fishing methods has been added to that from the dredge surveys in the faunal sections of the report of this survey.

This record is an overview entry for biological data collected on Soela cruise SO 1/88. This cruise took place in southeast Australian waters between Kangaroo Island, South Australia, and Portland, Victoria during 20 January - 11 February 1988, under the leadership of Nick Elliott. Biological data collected on this cruise include depth strata and number of orange roughy from 82 trawls. Orange roughy were caught in 75% of the trawls conducted between the 700 m and 1200 m depth contours with the best returns occurring within the 900 m to 1200 m depths. Other dominant species caught were spiky dory (Neocyttus rhomboidalis), slickheads (Alepocephalus spp.), warty dory (Allocyttus verrucosus), sharks (Deania calcea and Centroscymnus spp.) and eels (Diastabranchus capensis). Orange roughy from three 1200 m to 1400 m depth trawls. Biological information on 1514 orange roughy, and an additional 700 to 800 were measured and sexed. 90 samples of mature ovaries and 100 samples of liver, heart and muscle tissue for stock discrimination analysis by the University of Tasmania. 100 whole fish (>30 cm) from the western end of the survey and 60 from the eastern end, for stock discrimination analysis by the University of NSW. Viscera samples from both ends of the survey area for parasite analyisis by the University of Queensland. 63 gonad samples for histological study at the NSW Fisheries Research Institute. Acoustic data from the trawl survey area. Fish and cephalopod specimens for the Museum of Victoria. 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.

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 03/93. This cruise took place in waters off southern Tasmania during 7-22 April 1993, under the leadership of Brian Griffiths. Biological data collected on this cruise include samples of demersal fish, midwater nekton and zooplankton to determine the vertical distribution and diurnal movements of these three groups, and samples for trophic analyses. Acoustic data for biomass estimates. Oceanographic samples to determine the vertical and horizontal distribution of biological properties of the water column. 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.

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 02/91. This cruise took place in waters off the south and east coasts of Tasmania, around Maatsuyker Island, Flinders Island, St Helens Hill and approximately 40 miles east of Maria Island during 26 June - 16 July 1991, under the leadership of Tony Koslow. Biological data collected on this cruise include samples of fish and zooplankton from demersal, midwater and plankton tows. Stomach samples for gut content analysis. Acoustic data and target strength measurements of orange roughy. Orange roughy eggs including other fish eggs for vertical distribution examination, and for incubation and buoyancy experiments. 29 species of seabird were observed and recorded during the cruise: 5 albatross, 15 petrels, 1 storm-petrel, 1 diving-petrel, 1 gannet, 3 gulls, 2 terns, and 1 skua species. Whale observations were also recorded. CTD/productivity transects were also carried out east of Flinders Island, Pedra Branca and in the Japanese longline fishery area (off the east coast of Tasmania). 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.

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 01/97. This cruise took place in southern Tasmanian Continental Slope waters during 20 January - 1 February 1997, under the leadership of Tony Koslow. Biological data collected on this cruise include photographic surveys of four seamounts, dredge samples, faunal samples (including corals and many other benthic invertebrates) and fish samples. Samples of several species of corals, including Solenosmilia variabilis, were also taken for genetic analysis, and rock samples taken for age determination of the seamounts.
