Field experiments were carried out investigating prawn predation using tethering techniques at three sites in the Embley River in October 1994, December 1994 and April 1995.

Whaler collection records have been collated for use in conservation assessments. This MarLIN record refers specifically to a customised dataset that was created for delivery to the Department of the Environment and Water Resources (DEW). The dataset comprises distribution records of the freshwater speartooth shark, Glyphis sp. A, and the northern river shark, Glyphis sp. C, in northern Australia.
-
Surveys of of post-larval and juvenile animals, mainly fish, prawn and other crustaceans, were carried out in 1993 and 1994. Samples were collected using artificial settlement units in the Embley River estuary, Gulf of Carpentaria.
-
Two studies were carried out (October 1993 and March 1994) each lasting 24 hours, at one site in the Embley River, Gulf of Carpentaria. Juvenile prawn samples were collected every 2 hours by hand scoop or beam trawl in the river. Data were collected on gut fullness, moult stage, and prey type and number.
-
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.
-
This dataset contains species distribution, abundance and identity data of benthic invertebrates from the Pittwater region, NSW. Epifauna samples were obtained every 3 months from mangroves and saltmarshes between June 1991 and March 1991. Taxa identified consisted of 9 species of molluscs, all of which were gastropods. The data were taken as a control site for similiar sampling in Jervis Bay. The data are part of the Jervis Bay Marine Ecological Study. NB - As the database has been lost, the only data still available are those published in the JERVIS BAY BASELINE STUDIES Final Report.

Surveys of inshore fish catches, fish diets, and habitat and abiotic factors were carried out in the Embley River Estuary, Gulf of Carpentaria, between 1986 and 1992.
-
This dataset contains data on species distributions, productivity, reproduction and growth of mangroves and saltmarshes from Jervis Bay, NSW. The data were obtained from a variety of surveys and measurement techniques between October 1988 and July 1991. Taxa identified comprised of about 130 vascular flora species, 15 of which are exotic. Species numbers range from 2 species in the mangroves to more than 80 in the fringe forest. Population structures of the 5 dominant species - Avicennia marina, Aegiceras corniculatum, Casuarina glauca, Sclerostegia arbuscula and Gahnia filum vary spatially. Temporal change in populations of Avicennia has occurred over time intervals of 20 years, the other species appear to have remained stable over the past 50 years. 13 maps on the mangrove and saltmarsh complexes have been prepared at a scale of 1:4000. The Jervis Bay mangroves and saltmarshes were compared with other locations around Batemans Bay and Port Hacking. NB - As the database has been lost, the only data still available are those published in the JERVIS BAY BASELINE STUDIES Final Report.
-
Juvenile tiger prawns were collected by beam trawl in the Embley River, Gulf of Carpentaria in October 1993, March 1994 and October/November 1994. The following parameters were measured: prawn numbers, carapace length, species, seagrass, biomass, salinity, temperature and depth. Field experiments were carried out using enclosure nets.

This dataset contains data on species distributions, productivity, reproduction and growth of mangroves and saltmarshes from Port Hacking, Botany Bay, NSW. The data were obtained from a variety of surveys and measurement techniques from two creeks between 1989 and 1991. The data were taken as a control site for similiar sampling in Jervis Bay. The data are part of the Jervis Bay Marine Ecological Study. NB - As the database has been lost, the only data still available are those published in the JERVIS BAY BASELINE STUDIES Final Report.
