    Focussed habitat sampling of macrohabitats (defined by bottom type, soft hard or rough) in Gabo and Howe Reef mesohabitats (key study areas presenting a variety of shelf habitats describd by fishers) using fish traps from a commercial vessel. Traps were deployed and retrieved at dawn and dusk giving near equal day/night saoking times. 15 deployments (14 deployments of 5 traps, 1 deployment of 2 traps) yielded ~1 t fish.

    Focussed habitat re-sampling of macrohabitats (defined by bottom type, soft hard or rough) in three mesohabitats (key study areas presenting a variety of shelf habitats described by fishers) using gillnets and traps from a commercial vessel. Gillnets were deployed and retrieved at dawn and dusk giving near equal day/night soaking times. 19 deployments yielded 6,457 fish and squid weighing nearly 4 t. Fish and crab traps were set during the day only, yielding 979 fish specimens (589 kg) and squids and hermit crabs weighing 673 kg in total.

    Focussed habitat sampling of eight macrohabitats (defined by bottom type, soft hard or rough) in three mesohabitats (key study areas presenting a variety of shelf habitats describd by fishers) using fish traps from a commercial vessel (incidental catches were also taken with modified crab traps). Six of the macrohabitats were located in Disaster Bay off southern NSW, the other two were in Victorian waters off Pt Hicks. Traps were deployed and retrieved at dawn and dusk giving near equal day/night saoking times. 18 deployments yielded 1520 fish (~900 kg) and 258.5 kg hermit crabs. For full details see Williams and Bax (2001).

    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 4/86. This cruise took place in waters to the and east and north of Tasmania in two legs. Leg 1 from 8 - 17 July, and Leg 2 from 18 - 28 July 1986, under the leadership of F. R. Harden Jones. Aims:,br> Part 1 1. To carry out exploratory and experimental fishing in eastern and western waters of Tasmania, with particular reference to canyons, gullies, slopes, banks, sea mounts and depths of 1300 - 1500 m, making use of demersal and pelagic trawls, droplines and traps as in cruise 3/86. Particular attention will be given to handling of the catch. Part 2 1. To sample icthyop1ankton on the east coast of Tasmania and south east coast of New South Wales. 2. If blue grenadier larvae are found in the ichthyoplankton, to sample the adults of the species and to attempt artificial fertilisations. 3. To continue with the exploratory and experimental fishing studies on an opportunistic basis. 4. a. To collect water samples from approximately five stations. The samples collected will be from depths between the surface and 1000 meters and will be analysed for nutrients both total and dissolved forms. b. To collect water from a yet to be determined depth (less than 1000 meters) for storage experiments to be carried out over the following two years. c. To determine a horizontal nutrient profile in surface water from Storm Bay to Princess Wharf. The results to be correlated with underway temperature, salinity and fluorescence results.(derived from the cruise plan).(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.

    This record is an overview entry for biological data collected on Soela cruise SO 2/86. This cruise took place in the Tasman Sea at the south Tasman Rise during 13 March - 6 April 1986, under the leadership of T. Kenchington. Biological data collected on this cruise include orange roughy (Hopolostethus atlanticus) and other pelagic fish including whiptail (Macrourus sp.), slickhead (Alepocephalus sp.), and black dogfish. Ichthyoplankton samples and a large quantity of taxonomic material were collected. One Greenland shark (Somniosus sp.) was caught. Thirty nine species of seabirds were recorded including wandering and black browed albatrosses being among the most common and some rarities Gould's petrels, little shearwaters, South Georgian diving petrel, South Polar skua and some long-tailed jaegers.(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.

    This record is an overview entry for biological data collected on Soela cruise SO 3/86. This cruise took place in waters to the south and west of Tasmania in two legs. Leg 1 from 7 - 22 May, and Leg 23 May - 3 June 1986, under the leadership of F. R. Harden Jones. The plan was to carry out exploratory and experimental fishing in Tasmanian waters with particular reference to canyons, gullies, slopes, banks, and sea-mounts lying to the west and south of the island, making use of demersal and pelagic trawls, droplines and traps as in cruise 2/86. Catch included prawns and eels on Leg 1.(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.

    Dataset contains monitoring data from field surveys (mainly from crab-traps) on the distribution of European green crab (Carcinus maenas) in Tasmanian coastal waters, from January 1996 onwards. Data are also collected for bycatch of native crab species (including common shore crab Paragrapsus gaimardii, rough rock crab Nectocarcinus integrifrons, and ocean surf crab Ovalipes australiensis). The majority of data comes from keysites on the north-east (Georges Bay, Falmouth) and south-east (Little Swanport, Blackman Bay, Norfolk Bay) coast which are surveyed each late Spring to early Autumn (initially fortnightly, later monthly, most recently bimonthly). Data contains details of catch location, date, crab species, crab size, abundance, sex, gonad condition, limb loss, carapace colour. These data are collected as part of CSIRO's studies on the impacts and demographics of introduced marine species in Australian waters.

    This dataset contains the result of a biological baseline survey of the port region of Port Hedland, Western Australia, carried out in May 1998 by CSIRO Marine Research Centre for Research on Introduced Marine Pests (CRIMP). Collection methods employed include pylon scrapings, sediment cores, crab traps, plankton nets, and qualitative visual inspection and photographs (both still and video). Voucher specimens have been incorporated into collections of the West Australian Museum and CMR, Hobart. Taxonomic groups surveyed include marine invertebrates, fishes, phytoplankton, macroalgae, and marine vegetation. This dataset forms part of a series of Port Surveys conducted by CRIMP over the period 1996 to present.
