  • The distribution of juvenile penaeids and a variety of fish species within mangroves was determined using stake and fyke nets in the Embley River (Cape York).

  • This record describes micronekton samples obtained with the Isaacs Kid midwater trawl, a single warp trawl with a 2m x 2m square mouth opening, single net with 6mm bar mesh lining and a reinforced 20mm bar outer lining. Seven samples, collected from 7 stations on the Marine National Facility RV Investigator Event voyage IN2015_E04, a trial voyage -trace metals and micronutrients- for the RV Investigator departing Hobart on the 25th April and returning to Hobart on the 28th April, 2015.

    This record is an overview entry for biological data collected on Southern Surveyor cruise SS 08/95. This cruise took place in the North West Shelf during 18 August - 9 September 1995, under the leadership of Wade Whitelaw. Biological data collected on this cruise include demersal fish and invertebrate samples from 104 stations trawled and 35 mm camera photography of 33 stations trawled. Fish catches were identifed and weighed by species with up to 90 species being caught per half hour trawl. Greatest diversity occurred at the shallower stations. Length frequency data was collected for 14 species of fish (see taxonomy keywords), and otoliths were collected for 4 of the major species (L. sebae, L. choerorynchus, S. undosquamis and N. furcosus). Approximately 50 taxonomic voucher specimens and 100 other specimens were photographed and retained for the Handbook of Australian Seafood, and about 80 specimens and 400 muscle samples were kept for the fillet analysis study. Another 80-90 unidentified specimens were also retained, being mainly deep water species, mustelus species and samples of lizard fish. 6 'fish down' trawl experiments were completed and all fish identified, counted and weighed by species with 30 stomachs collected from Lethrinus genivittatus, L. choerorynchus, Memipterus furcosus and Saurida undosquamis. Video photography and 35 mm camera photography of the trawls were also obtained. 3 hydrographic transects were completed with the sumbersible data logger (SDL) and over 195 species of sponges for taxonomic studies by the Queensland Museum were collected. 125 humpback whales and 8 unidentified cetaceans and approximately 120 dophins were also observed during the cruise.

    This record is an overview entry for biological data collected on Southern Surveyor cruise SS 04/91. This cruise took place in the North West Shelf during 12-30 September 1991, under the leadership of Wade Whitelaw. Biological data collected on this cruise include demersal fish and invertebrate samples from 105 stations, with up to 70 species being caught per 30 min trawl. Greatest diversity occurred at the shallower stations. Length frequency data for 14 species of fish (see taxonomy keywords) and otoliths for 4 of the main species (L. choerorynchus, S. undosquamis, N. furcosus and L. sebae) were collected. Numerous fish specimens were retained for further taxonomic identification and stock discrimination studies. Live berried scampi samples were obtained from 3 scampi trawls for larval rearing studies (UWA). 35 mm camera photography of 63 trawls including video photography of the last trawl to study the effects of the trawl on the benthos were obtained. Numerous whale sightings were also observed during the cruise and 3 hydrographic transects were completed with the submersible data logger (SDL).
