Improving risk management of paralytic shellfish toxins (PST) in the Blacklip Abalone (Haliotis rubra rubra)

The accumulation of paralytic shellfish toxins (PST) of microalgal origin in abalone tissues causes a trade and human health risk that requires active management. Toxic algal blooms of the genus Alexandrium have recently caused several abalone harvest closures on the east coast of Australia. Risk...

Need

The cross-Government LNFSWG has been working with stakeholders since 2015 to address ongoing industry and community concerns over the economic impacts of fur seals on the LCF, including depredation of catches and damage to fishing gear. Despite recent mitigation initiatives, reports from industry suggest that the seal-fisher conflict and associated economic impacts have intensified in recent years. In an effort to reduce financial pressure on licence holders, the SA Government (PIRSA Fisheries and Aquaculture) has waived cost-recovered licence fees for the net sector of the fishery, as well as implemented other more flexible management arrangements, for the 2015/16, 2016/17, 2017/18 and 2018/19 fishing seasons. Although these measures have been welcomed by industry, it is not clear whether the current level of support for fishers is adequate or how to evaluate the costs and benefits of alternative mitigation options or management interventions.

There has also been industry and community concerns about the potential impact that seals are having on waterbirds, fish populations, and on the broader Lakes and Coorong ecosystem, with some sectors advocating for seal numbers to be managed to mitigate these perceived impacts.

There is a need for reliable, quantitative information on the nature and extent of the economic and ecological impacts of seals in Lakes and Coorong region, and the factors that attract seals to the region and drive the seasonal increase in fur seal numbers. This information will support processes to identify, prioritise and develop practicable and cost-effective long-term policy/management strategies to manage long-nosed fur seal numbers and mitigate their impacts in the Lakes and Coorong region, during and after the project.

Objectives

1. Assess the economic impact of seal interactions on Lakes and Coorong commercial gillnet fishers.
2. Assess the ecological impacts of seals on the Lower Lakes and Coorong ecosystem.
3. Assess the spatial and temporal use of the Lower Lakes and Coorong region by seals to identify key haul-outs, movement corridors, foraging areas and overlap with fishing effort.
4. Identify options to manage seal numbers and evaluate their costs and benefits to mitigate their impacts.

Validation and implementation of rapid test kits for detection of OsHV-1

Following the outbreak of Pacific Oyster Mortality Syndrome (POMS) in the Port River, South Australia in summer 2017-18, a need was identified for rapid diagnostic technology for OsHV-1, the causative agent of POMS. During the February 2016 OsHV-1 outbreak in Tasmania, tracing activities in...

Validating a new sampling technique for estimating egg production

Estimates of spawning biomass obtained using the Daily Egg Production Method (DEPM) are the primary biological performance indicator in the South Australian Sardine Fishery (SASF) and Commonwealth Small Pelagic Fishery (SPF). The DEPM is also being used to assess the status of other...

Spawning biomass of Jack Mackerel (Trachurus declivis) in the East sub-area of the Small Pelagic Fishery during summer 2019

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). The objective of this study was to conduct ichthyoplankton and adult trawl surveys that underpin the DEPM in the...

ESD risk assessment for under-utilised species to facilitate structural reform of South Australia's commercial Marine Scalefish Fishery

South Australia’s Marine Scalefish Fishery (MSF) is facing a number of complex issues that are affecting business profitability and stock sustainability. One particular issue relates to the long-term reliance of the fishery on the three primary finfish species of King George Whiting, Snapper...

Future oysters CRC-P: Species diversification to provide alternatives for commercial production

Pacific Oyster Mortality Syndrome (POMS), the disease caused by OsHV-1 microvariant, results in high and rapid mortality in Pacific Oysters (Crassostrea gigas) and has been responsible for significant economic loss to oyster industries in Australia and around the world. The diversification of...

Mud cockle (Katelysia spp.) stock enhancement/restoration: practical implementation and policy evaluation

This study was conducted to restore the Mud Cockle population in the Section Bank of Port River, South Australia, which had drastically decreased due to commercial fishing. Mud Cockles are important not only for commercial purposes but also for stabilizing sediment and reducing turbidity in the...
