This report provides biological information, survey and commercial catch and effort data on the two by-product species of the Spencer Gulf Prawn Fishery to: 1) assess vulnerability to current trawling activity, and 2) identify management options to address sustainability issues. ...
Bycatch in rock lobster and shark gillnet fisheries has been identified as a key threat to the threatened ASL. This project aimed to: i) develop pot protection devices to mitigate entrapment of ASL in the SARLF...
In response to severely reduced water levels and increasing salinity in Lake Albert PIRSA (Primary Industries and Resources South Australia) Biosecurity initiated a trial fish-down to determine the effectiveness of this technique in reducing the biomass of common carp (Cyprinus c...
Spatial segregation of species, due to differences in habitat use, is important for the health and structure of fish communities. River regulation in the Murray-Darling Basin has resulted in altered flow regimes, restrictions to fish movement and decreases in available habitat fo...
This fishery assessment report assesses the current status of the Blue Crab Fishery (BCF) in South Australia up to July 2009....
During the 2008/09 season, 21 tonnes of giant crab were harvested from South Australian waters. Most of this catch (74%) was harvested by two miscellaneous licence holders rock lobster fishers with giant crab quota entitlements accounted for 17% of the total, while the remainder ...
There are many marine fish species that inhabit South Australian waters for which there is no or limited understanding of the population biology. There are management issues for some such species that are taken as by-catch in various line and net-based fisheries. This study aimed...
Water levels in the Lower Lakes are currently the lowest on record and with predictions of continued below average inflows, levels are likely to continue receding. Receding water level has resulted in the exposure of extensive areas of acid sulfate soils, which upon reaction with...
Fish spawning and recruitment studies are a good indicator of river and fish population health. Larval fish sampling in the Lower River Murray was conducted fortnightly from 2005 -2008, at Locks 1 and 6, from October to December, resulting in six trips per year....
This report describes the composition, distribution and diets of demersal fishes collected from Spencer Gulf during a quantitative Gulf-wide trawl survey in February 2007....
