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...

Gear interaction of non-targeted species in the Lakes and Coorong commercial and recreational fisheries of South Australia

This project was developed by SARDI, in consultation with PIRSA, Lakes and Coorong Fishery (LCF) licence holders and relevant stakeholders, over several years. Proposals to investigate interactions with non-target species and discarding from the LCF in the Murray River estuary and Coorong...

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...

Developing alternative strategies for managing seal-fisher interactions in the South Australian Lakes and Coorong Fishery

This report assesses the efficacy of alternative strategies for managing seal-fisher interactions in the gillnet sector of South Australia’s Commercial Lakes and Coorong Fishery (LCF), including the use of deterrents and alternative fishing methods. It uses a range of information obtained...

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.
