    A total of 11 research cruises were carried out on the "Milana J", "Island Girl" and the FRV Southern Surveyor between 1993 and 1995 to study ponyfish (Leiognathid) biology and ecology. Data were collected on ponyfish length, weight, sex and gonad weight.

    Sea snakes were collected in the eastern Gulf of Carpentaria from prawn trawls taken during a number of research cruises. The sea snakes were taxonomically identified, with 16 species being found.

  • This record describes a derived data set of museum records collated and quality assured in 2015 by Shirley Sorokin (SARDI), Franzis Althaus (CSIRO), Karen Gowlett-Holmes (CSIRO) and Jason Tanner (SARDI) under the GAB Research Program. The GABRP aims to describe the key elements of the GAB marine ecosystem. This understanding of the structure and function of the ecosystem will be used to inform future integrated and sustainable ocean management and assessment/mitigation of potential future impacts. The collation and examination of museum data contributed to our endeavor of documenting existing knowledge of species distributions in the GAB region. Museum database managers were asked to provide an inventory of all specimens listed in their respective data bases that were collected in Australian waters between Perth and Sydney at >=200 m depth. The data were collated and CAAB identifiers were added taking into account differences in spelling, synonyms (outdated names) etc. Where uncertainty in an identification existed the next higher level in the taxonomic hierarchy was used for assigning CAAB.

    Shark collection and live feeding experiments were carried out at Weipa, far north Queensland.

    Surveys of inshore fish catches, fish diets, and habitat and abiotic factors were carried out off the coast of North-west Groote Eylandt, Gulf of Carpentaria, in 1989 and 1990.

    Surveys of inshore fish catches, fish diets, and habitat and abiotic factors were carried out in the Norman River estuary, Gulf of Carpentaria, between 1991 and 1992.

    A stratified random grid survey of five areas in the Gulf of Carpentaria was carried out in June 1990 using demersal fish trawls with a 100mm codend on a commercial trawler. Lutjanids and other large commercial finfish were surveyed.

    Acoustic data (120 kHz), CTD, fluorometer & light meter data, zooplankton samples with a 333 um mesh net (vertical hauls). Survey off Ningaloo Reef, Western Australia, 4-11 May 2001. Samples collected on onshore-offshore transects with acoustic data sampled between stations. CTD stations at 25, 50, 75 & 100 m depths; plankton samples at 25, 50 & 100 m. Samples also directed at acoustic targets, whale sharks, feeding fishes, etc.

  • Sampling was carried out in October 1993 and March 1994 to collect fish and juvenile prawns. Fish gut contents were examined. Sampling took place at two sites in the Embley River using gillnets, beach seines, rotenone, and beam trawls.

    The Photographic Index of Australian Fishes (PIAF) is a collection of over 40,000 colour transparencies of some 2,500 fish species, representing more than half of the Australian fish fauna, held in conjunction with the Australian National Fish Collection (formerly the I.S.R. Munro Ichthyological Collection). It encompasses all of Australia's commercial seafood species, and contains the only photographs in existence of many bycatch species. It contains images of species from rivers and estuaries, from near-shore to the deep ocean, from the temperate regions to the tropics, as well as from remote offshore islands and the sub-Antarctic. CSIRO marine scientists have assembled PIAF over the last 30 years as a by-product of coastal and deep ocean surveys. PIAF images of commercial species have recently been published in the Australian Seafood Handbook, and also been used extensively in several books, such as South East Fishery Quota Species: an identification guide, Field Guide to Trawl Fish from Temperate Waters of Australia and Continental Shelf Fishes of Northern and North-Western Australia.
