Southern Rock Lobster Planning and Management for a National Research Development & Extension (RD&E) Program
The operating environment for Southern rock lobster fishing and exporting businesses has changed significantly since January 2020. Prior to this the value of the catch (beach price) has remained consistently high (average around $80/kg with highs up to $120/kg). Investment has had an exceptional ROI in this industry due to the scale of the fishery. This has enabled the fishery to engage in a progressive research agenda which focused on consolidation of knowledge and expansion of existing programs (biotoxins, lobster health, supply chain development).
However, the global pandemic and trade disruptions to the live export market in China have seen a precipitous decline in beach price (as low as $25/kg) making some operations unviable. Ongoing trade disruption has brought about a need for industry to urgently adapt to new markets and market offerings. Changing consumer preferences are demanding that out sector make further advancements in carbon and waste reduction as well as the circular economy. Performing in a changing climate will also be a focus of the fishery going forward.
The Southern Rock Lobster industry has a complex array of business structures. Many of the quota units or catch shares are owned by small family businesses while an increasing amount is owned by larger companies. Catch is taken by around 600 vessels and packed and processed by a number of different companies. The large and complex array of firms across three States means there is a need for leadership in prioritising and coordinating the investment in and managing industry RD&E.
SRL remains an active supporter and stakeholder in SafeFish and the Seafood Trade Advisory Group (STAG) to primarily address issues regarding food safety and international market access. The continuance of these relationships are paramount to the SRL industry's success to service new and existing markets as well as build on domestic opportunities.
This project will build on the existing capacity to deal with Southern Rock Lobster RD&E needs in a strategic and efficient way. The industry will benefit from continued collaboration on R&D initiatives with other Australian Rock Lobster representative bodies.
Stable isotopes: a rapid method to determine lobster diet and trace lobster origin?
1. Tracing lobster origin
The need for determining whether stable isotopes are a useful tool for diet analysis and identification of catch location is a priority for the SRL fishery. If proved useful, this technology will allow for rapid identification and isolation of stock abnormalities – such as toxic algal blooms, which has potential to save a lot of time and money for fisheries management.
2. Invasive urchin controls
If results show that small lobsters do predate on urchins, this will be important for informing stock rebuilding targets and reference points relative to urchin control. Primarily we could advise on whether urchin control targets and performance indicators should be based on total lobster biomass or only large lobster biomass. For example, if small lobsters (140mm CL) are found to actively predate on small urchins, the pressure to rebuild the large lobster biomass (>140mm CL) may be reduced. This could in turn help to adapt the rebuild strategy, in line with effective urchin control.
