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...
From 2014-15 to 2018-19, the Commonwealth Environmental Water Office (CEWO) Long- Term Intervention Monitoring (LTIM) Project was implemented to monitor and evaluate ecological outcomes of environmental water delivery in the Lower Murray River (LMR), along with six other Selected...
This report assesses the current status of the Blue Swimmer Crab (Portunus armatus) resource and provides the latest estimates of the biological performance indicators (PIs), information in context of the reference points (RPs) and stock status classification described in the dra...
Traditionally, management of marine activities has occurred on a sector-by-sector basis, with limited consideration of the interactions between different activities and users, or their cumulative impacts. There is increasing global recognition of the need for Integrated Managemen...
From 2014-15 to 2018-19, ~3,440 GL of Commonwealth environmental water was delivered through a series of watering events to the Lower Murray River (LMR), coordinated to achieve a range of environmental outcomes across the southern connected Murray-Darling Basin. This report prese...
