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...

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...

Need

South Australia’s Marine Scalefish Fishery (MSF) is currently undergoing a strategic review with the principal aim of restructuring the fishery in order to ensure its long-term sustainability and economic viability. The heterogeneous mixture of participants, fishing devices, licence conditions and regulations associated with this fishery makes the tasks of administering and managing it extremely challenging. These complexities intertwined within a highly dynamic fleet that is capable of shifting fishing effort amongst species and regions often alters the emphasis of its overarching management. Industry and Government are working collaboratively to address the inherent complexities of the fishery through firstly developing a mechanism to rationalise the fleet, then reforming its overall structure, and ultimately refining its future management. In order to optimise this structural reform, it is necessary to disentangle and understand the fleet dynamics of this extremely complex fishery. This project aims to explore the implications of strategic management options (e.g. regionalisation, licensing, ITQ’s and ITE’s) on the future structure and viability of the MSF, from resource sustainability, economic and social perspectives.

Objectives

1. To review the structure and function of multi-species, multi-gear fisheries around the world.
2. To disentangle the complexities of the South Australian commercial Marine Scalefish Fishery to describe long-term spatio-temporal trends in the composition, dynamics and socio-economic performance of the fishing fleet
3. To evaluate the possible strategic management options such as regionalisation, licensing, ITQs and ITEs on the future structure and viability of South Australia’s MSF
4. To determine the biological, economic and social 'carrying capacity' of the MSF across key regions of the fishery.

Summary

This study was undertaken by the South Australia Research and Development Institute (SARDI) in collaboration with PIRSA Fisheries and Aquaculture, BDO EconSearch, the Marine Fishers Association (MFA), Fishwell Consulting and University of Canberra. This project guided the reform of South Australia’s commercial Marine Scalefish Fishery (MSF) by providing scientific advice and analyses to underpin its implementation. The MSF is a multi-sector, multi-gear and multi-species fishery, making any management reform a complex and difficult process. Both the sustainability of key stocks and commercial fishery’s economic performance have been deteriorating over a 20-year period; significantly influenced by fishery overcapitalisation. Simply put, there were too many fishers and not enough fish to support a vibrant and sustainable commercial fishery. This was addressed through the three ‘pillars’ of the reform: regionalisation, unitisation and rationalisation. These pillars were reflected in the reform with: 1) the creation of four new zones of management; 2) implementation of individual transferable quotas (ITQs) for appropriate ‘Tier 1’ stocks; and 3) rationalisation of the commercial MSF fleet by removing one third of licences through a voluntary licence surrender program (VLSP). These pillars were supported by research on the biological, economic and social carrying capacity of the fishery. The reform was implemented on 1 July 2021 resulting in a fishery that has regional management with appropriate output controls and a reduced fleet size.

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...
