Spencer Gulf fisheries, Prawn Fisheries Catch and Effort Logbook Data
공공데이터포털
The Western King Prawn species (Penaeus latisculcatus) is landed from South Australian (SA) waters. The prawn industry in SA is divided into the Gulf St Vincent, Spencer Gulf, and West Coast fisheries. A separate fishery in Investigator Strait operated until 1986/87 when it was amalgamated into the Gulf St Vincent fishery. The Gulf St Vincent fishery was closed in 1991/92 and 1992/93. The West Coast fishery was voluntarily closed in 1992/93. This system monitors catch and effort fluctuations in the state's prawn industry. The quantity of prawns (kg) and effort (hours trawled) to catch the prawns are recorded for each fishing period from records submitted by the trawler operators.
Spencer Gulf fisheries, Blue Crab Pot Fishery Catch and Effort Data
공공데이터포털
Blue Swimmer Crab daily catch and effort data. Spencer Gulf and Gulf St Vincent, South Australia since 1997.
Spencer Gulf prawn trawl by-catch data
공공데이터포털
By-catch species distribution and abundance data collected from prawn trawl surveys, throughout Spencer Gulf, South Australia between 1994 and 2007.
Spencer Gulf fisheries, Sardine Research Catch and Effort Logbook Data
공공데이터포털
Monitor catch and effort fluctuations in South Australia's sardine fishery and to provide a basis for assessment of fish stocks. Quantity of fish and effort expended in taking the catch is recorded by trip logbook returns submitted by the pilchard fisher on a shot by shot basis. Ongoing since 1999.
Spencer Gulf prawn fishery-independent survey data
공공데이터포털
Prawn abundance, distribution and size structure from fishery-independent surveys throughout Spencer Gulf, South Australia since 1982.
Spencer Gulf and Gulf St Vincent marine ecology: reef health
공공데이터포털
Data on benthic cover and fish abundance at a number of coastal reefs along the Adelaide coast, Fleurieu Peninsula and Yorke Peninsula, South Australia. Surveyed in 2005 and a subset in 2007.
Spencer Gulf fisheries, Marine Scalefish Fishery Catch and Effort Logbook Data (includes Miscellaneous Fisheries)
공공데이터포털
The Marine Scale Fishery has traditionally been one in which fishing effort shifts temporarily and spatially between species, depending on their relative abundance and value. SARDI research projects have concentrated on providing information on key biological parameters of several of the major species, including King George whiting, Snapper, Garfish, and Southern calamary. The Marine Scale system monitors catch and effort fluctuations in South Australia's Marine Scalefish fishery and provides a basis for assessment of fish stocks. Quantity of fish (by species) and effort (by gear) expended in taking the catch is recorded by monthly returns submitted by the commercial fisher.
Spencer Gulf Abalone fishery monitoring
공공데이터포털
Fishery independent surveys of greenlip abalone in the Spencer Gulf, South Australia from 1968 onwards.
Spencer Gulf Blue Crab pot-sampling
공공데이터포털

Marine Biological Survey of the Southern Kimberley, Western Australia.
공공데이터포털
This report describes the results of the first of three expeditions planned to the Kimberley to document the marine flora and fauna of the area. The expedition took place in November 1994 with the assistance of a grant from the National Estates Grant Program.Twenty-two stations were examined. Detailed notes are presented on the station locations and habitat types present. At each station seagrasses, algae, fish, and some invertebrate groups were collected and notes were made on mangroves in the area.Three areas of particular significance were found: the intertidal seagrass beds in the area of Sunday and Tallon Islands, which are the largest known for the Kimberley region; an extensive intertidal system which surrounds Montgomery Island with an area greater than 400 square kilometres; and a hypersaline lagoon on Macleay Island. These areas are described and the reasons for their significance detailed.This report provides an extensive section outlining the coastal geomorphology of the southern Kimberley islands, emphasising the unique intertidal terraces which trap water at low tide and have allowed the development of the seagrass systems at Sunday and Tallon Islands.There have been no published records of the marine algae which occur in the Kimberley. This report provides details of 72 species collected during the expedition. Coralline algae are poorly known and species in this group are currently being worked on taxonomically. Two genera commonly found during the trip are provisionally considered to be undescribed and two species are new records for Western Australia. Eight species of seagrasses were recorded from a total of 15 stations; the number of known localities at which the most common species occurs has been trebled.Two hundred thirty-two species of molluscs, 173 crustaceans, 24 polychaetes,and 197 species of fish were recorded. Potentially new species were found in several groups. Detailed collections were made of additional groups such as echinoderms. The first collections from the Kimberley were obtained of groups such as isopods and nemerteans.The taxonomy of many of the groups collected is poorly known. Material was obtained for specialists in particular groups in Australia and overseas. The material has been sorted and sent to the specialists for examination and determination of species. This work is complex and time consuming, so it has not been possible to provide identifications for this report. However, the material is currently being worked up and will be presented in the scientific literature when it has been completed.
