Habitat modification and its influence on prawn and crab fisheries

Experimental trawling in Gulf St Vincent indicated that epifaunal assemblages experienced substantial trawling mortality, which varied depending on sediment characteristics. Locations with strong currents and coarse sediments experienced minimal effects, whereas those with weak currents and...

Application of tracking technologies to understand space-time explicit patterns of movement, residency and habitat use of pelagic sharks in Spencer Gulf: resolving overlaps with key community activities and marine industries

The report focuses on the movement dynamics of two pelagic sharks, the White Shark (Carcharadon carcharias) and Bronze Whaler (Carcharinhus brachyurus), in South Australia. Specific aims were to: (1) determine if aquaculture activities correlated with patterns on fidelity and migration; and (2)...

The influence of fish movement on regional fishery production and stock structure for South Australia's Snapper (Chrysophrys auratus) fishery

From 2007 onwards, South Australia’s snapper (Chrysophrys auratus) fishery underwent significant and unprecedented changes that impacted on the management of the fishery. This ultimately reflected our poor understanding of the movement behaviour of snapper and its consequences for...

Development of an integrated fisheries management model for King George whiting (Sillaginodes punctata) in South Australia

The King George Whiting Simulator (WhitSim) is a simulation version of the Whiting Estimator (WhitEst) encased inside a graphical user interface (GUI) that includes geographical information systems (GIS). WhitSim provides the ability to simulate various management strategies and parameter scenarios...

Field trials to experimentally test if alternative sea lion excluder devices (SLEDs) adequately prevent Australian sea lions from entering rock lobster pots

This project tested the efficacy of two new sea lion excluder devices (SLEDs) in preventing entry of seals into southern rock lobster (Jasus edwardsii) pots designed by fishers from the South Australian Northern Zone Rock Lobster Fishery (NZRLF). Since 1 November 2013, the use of a spike SLED has...

PIRSA: Surveying, searching and promoting cuttlefish spawning activity in northern Spencer Gulf

The size of the Giant Australian Cuttlefish (Sepia apama) population on the Point Lowly spawning grounds in 2014 increased for the first time since 2009, yet management is remaining cautiously optimistic as the reason for this increase is currently unknown. In addition to the annual assessment...

King George Whiting spawning dynamics in South Australia’s southern Gulfs: to inform improved assessment and management of the resource

This study investigated the spawning dynamics of King George Whiting (Sillaginodes punctatus) in South Australia’s southern gulfs and Investigator Strait. King George Whiting is one of the most valuable and iconic coastal finfish species of southern Australia. In South...

Maximise yield or minimise risk in the Blacklip Abalone fishery: using biological data to direct harvest strategies

The primary goal of this research was to identify attributes of the seasonal biology of Blacklip Abalone (Haliotis rubra; hereafter referred to as Blacklip) that may be beneficial for optimising fishing strategies. The optimum months to harvest Blacklip to maximise yield were identified using a...
