This stock assessment report for the South Australian Snapper fishery continues the series of annual assessment or status reports since 1997 that report the statuses of the stocks. Here, the statuses were assigned at the scale of biological stock for the Spencer Gulf / West Coast...
Two adult specimens of the Asian paddle crab (APC), Charybdis japonica, were captured in Gulf St Vincent (GSV) in 2019 by commercial and recreational fishers, including one specimen captured near Port Adelaide. Crabs of the genus Charybdis have been introduced and formed invasive...
This stock assessment determined the status of South Australia’s Northern Zone Rock Lobster Fishery (NZRLF) through analysis of data from several long-term monitoring programs. The performance indicators in the current harvest strategy are not linked to a definition of stock stat...

This report provides an assessment of stock status for Blacklip Abalone (Haliotis rubra) and Greenlip Abalone (H. laevigata...
The Chowilla anabranch system, which bypasses Lock and Weir 6 on the River Murray, consists of a range of aquatic habitats, including permanent lotic (flowing water) creeks that are now rare in the region. The presence of flowing water habitats within Chowilla is fundamental for ...
Video transects were undertaken along a number of survey lines off the Light River in 2011 and Port Adelaide in 2014, primarily to assess seagrass condition in these regions. In addition, epiphyte loads were scored from the video footage as a potential indicator of nutrient stres...
Pouched lamprey (Geotria australis) and short-headed lamprey (Mordacia mordax) are the only anadromous fishes native to the Murray–Darling Basin (MDB). Historically, lamprey were common in the River Murray with spawning migrations potentially extending up to 2,000 km upstream, bu...
Estimates of spawning biomass obtained using the Daily Egg Production Method (DEPM) are the primary biological performance indicator for quota species in the Small Pelagic Fishery (SPF). Estimates of spawning biomass are used to set Recommended Biological Catches (RBCs) and Total...
This report provides estimates of harvestable biomass for Vongole (Katelysia spp., also known as mud cockles) to inform setting of annual total allowable commercial catches (TACCs) under the harvest strategy in the Management Plan. Stock status was determined using a weight-of-ev...
