Species identification of Australia’s most significant octopus fishery – the Western Australian Common Octopus

This report summarises the scientific and consultation work undertaken to identify a new species name (Octopus djinda) and new common name (Western Rock Octopus) for the species that supports Australia’s largest octopus fishery, with 734 tonnes harvested in 2022. The species had been...

Assessment of the Inflamark method as a sensitive and cost-effective measure of oxidative stress in cultured fish

This collaborative project between industry and academia was developed in response to the need for a reliable and simple measurement of fish health status in farmed populations as well as in a research context, to assess the outcomes of trials on health, nutrition and environment. We have developed...

Developing novel remote camera approaches to assess and monitor the population status of Australian sea lions

This project trialled the use of remote cameras to monitor the relative abundance of Australian sea lions (ASLs, Neophoca cinerea) at three Western Australian (WA) breeding colonies. The research was undertaken by the Department of Primary Industries and Regional Development (DPIRD) to assess...

Aquatic Animal Health and Biosecurity Subprogram: Perkinsus olseni in abalone - development of fit-for-purpose tools to support its management

The project was able to successfully propagate a new P. olseni isolate from Queensland and successfully cultured the isolates from Spain, Japan, New Zealand, and South Australia as well as P. chesapeaki, which was used as a negative control. We were unable to culture the Western Australian (WA)...

Understanding recruitment variation (including the collapse) of Saucer Scallop stocks in Western Australia and assessing the feasibility of assisted recovery measures for improved management in a changing environment

This study examined possible contributing environmental factors to the recruitment variability of the Ballot’s saucer scallop Ylistrum balloti across the main stocks in Western Australia. The project was undertaken to explain the variation observed between years and between regions as well...

Need

Australia’s aquarium industries are high value (collectively GVP values >$20 million), small scale fisheries that rely on exporting CITES listed corals for profitability and viability. The Australian government requires fisheries collecting and exporting CITES listed species to demonstrate that their harvest is sustainable. This is achieved through the provision of a successful non-detrimental finding and accrediting the fishery as an approved Wildlife Trade Operation (WTO) under the EPBC Act. There is growing international pressure for Australia to unequivocally demonstrate sustainable collection practices for CITES listed species. However, data-poor fisheries like the aquarium fisheries, struggle to provide sufficient quantitative data supporting the non-detrimental use of CITES listed species. This has resulted in severe restrictions on allowable harvest levels tied to WTO approvals and industry viability is at risk.

Many of the coral species taken by the marine aquarium industry across northern Australia are in inter-reef turbid water environments that are poorly studied. In addition, many of the species are documented as rare or uncommon although they may be locally abundant in these turbid waters environments. A recent Ecological Risk Assessment of the Queensland Coral Fishery (May 2013) identified the priority need to fill these data gaps to better quantify the level of impact on corals from commercial collection.

Abundance baselines for these species are required to demonstrate sustainable use and support export approvals. Species identification of harvested corals also needs to be clarified as this information is critical for aligning catch data with scientific information on the vulnerability of different coral species. This will lead to the development of monitoring protocols for the industry, and in the longer term, to demonstrate sustainable harvest.

Objectives

1. Establish the distribution and abundance of commercially important coral species in selected inter-reef habitats
2. Improve the accuracy of species identifications across the industry
3. Establishing abundance and turnover of representative commercially important inter-reefal corals
4. Establish a cost effective industry based long-term monitoring program
5. Undertake consistent Ecological Risk Assessments (ERA) in NT and WA to establish vulnerability of major target species

Summary

The objectives and outcomes of this project were three-fold. Firstly, we established the abundance and turnover of select, commercially important coral species in areas of concentrated fishing across northern Australia. Improved understanding of the biology and ecology of harvested corals is fundamental to establishing baselines and sustainable harvest levels. Secondly, we helped to refine species-level taxonomy for commonly harvested coral species, using genetic analyses, to better establish what is being harvested and where. Genetic analyses on corals collected from different jurisdictions helped to reveal which species are very widespread, and therefore more resilient, versus those that are geographically restricted, and therefore warrant specific management attention. Thirdly, we explored species-specific vulnerability to extrinsic pressures on coral stocks, related to environmental change. Climate induced coral bleaching if the foremost threat to coral species and could undermine the sustainability of ongoing coral harvesting independent of fishery effort or take.

An industry based mark recapture program to provide stock assessment inputs for the Western Rock Lobster Fishery following introduction of quota management

The West Coast Lobster Managed Fishery (WCRLMF) moved from input to output controls in 2010. This change directly affected the relativity of a number of fisherybased data sources, making assessment of the fishery more problematic. A novel examination of the stock dynamics was required to help ensure...
