Climate driven shifts in benthic habitat composition as a potential demographic bottleneck for Western Rocklobster: understanding the role of recruitment habitats to better predict the under-size lobster population for fishery sustainability

The West Coast Rock Lobster Managed Fishery (WCRLMF) is one of the most valuable and sustainable single-species fisheries in Australia. WCRLMF is managed, in part, using larval (puerulus) settlement indices obtained from artificial seagrass stations that are continuously monitored at eight locations...

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...

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...

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.

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...

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...
