Storm Bay Observing System: Assessing the Performance of Aquaculture Development

In Tasmania, farming of Atlantic salmon (Salmo salar L) has developed rapidly since the first trials in 1985 and has grown progressively to the current 60,000 tonnes produced in 2020.. Salmon farming in open sea cages produces organic and inorganic wastes which have the potential to impact the...

Optimisation of treatment of Cryptocaryon irritans in Barramundi aquaculture

Need

Significant losses of farmed barramundi have occurred in coastal marine aquaculture sites utilising marine water sources due to Cryptocaryon irritans infestations. The disease costs have had substantial impacts on commercial aquaculture operations. Cryptocaryon irritans has a direct life cycle with an adult in the skin or gills of the fish and asexual reproduction in the environment away from the fish. The life cycle of C. irritans is temperature and host dependant and treatment must be timed with critical phases of the life history to maximise efficacy. This project will establish this timing to provide guidelines for optimised treatment.

The existing treatments have substantial costs ($3K+/treatment) and a sub-optimal profile for environmental release with high toxicity and environmental persistence. This project will optimise doses of existing treatments, and identify and assess new treatments. Products identified as effective and safe will have optimised guidelines developed for delivery to ensure the best outcome for farms and the environment. Such improvements will support further expansion of the finfish aquaculture industry in Northern Australia.

Objectives

1. Describe the life cycle of Australian C. irritans isolates from Barramundi aquaculture, and describe relevant treatment intervals for different temperatures for C. irritans to maximise benefit from each treatment
2. Screen candidate treatments to identify new products for further assessment
3. Establish efficacy and safety of optimised doses for current treatments and selected candidate treatments in laboratory and small-scale field trials
4. Optimise delivery under field conditions for delivery of new treatments

Need

This project is needed as there are knowledge gaps about the effect of recreational fishing on the health and wellbeing of recreational fishers. Recent years have seen many claims about the health and wellbeing benefits of recreational fishing, as well as growing interest in nature connection and outdoor recreation as wellbeing interventions more generally. Measuring and valuing the wellbeing benefits of recreational fishing is not currently possible due to a lack of evidence, and limited methods for monitoring, measuring and reporting wellbeing effects. The FRDC’s RD&E Plan 2015-20 aims by 2020 to have robust community net benefit metrics that enable measurement of the benefits of fishing. This project will develop robust metrics related to health and wellbeing benefits of recreational fishing. Achieving this requires better understanding both (i) whether and under what circumstances engaging in recreational fishing has measurable impacts on health and wellbeing, and (ii) how to measure these benefits to produce readily accessible and understandable metrics. This will help achieve the FRDC’s national research strategy deliverable ‘Social contribution is supported by the fishing and aquaculture sector so it can capture the non-monetary value of activities across sectors.’ This work will also contribute to national science and research priorities in the health field, specifically the priority ‘Build healthy and resilient communities throughout Australia by developing … preventative strategies to improve physical and mental well-being’ (http://www.science.gov.au/scienceGov/ScienceAndResearchPriorities/Pages/Health.aspx). Nationally, this research priority aims to develop strategies for supporting wellbeing. This project contributes by identifying the role recreational fishing can play in building healthy and resilient communities through supporting physical and mental wellbeing. This research will also contribute to the overarching aims of Australia’s rural research, development and extension strategy, which include ‘develop a range of technologies and knowledge to contribute to healthy Australian lifestyles’ (http://www.agriculture.gov.au/SiteCollectionDocuments/ag-food/innovation2/nsrrdip-investment-plan1.pdf)

Objectives

1. Understand whether engaging in recreational fishing (or in particular types or frequency of fishing) is associated with improved health and wellbeing for individual recreational fishers using available datasets
2. Identify best practice methods for establishing a causal relationship between (i) engaging in fishing and (ii) health and wellbeing outcomes for individual recreational fishers
3. Produce proposed set of measures and associated methodology that can be used to robustly measure causal association between engaging in fishing and health & wellbeing for individual recreational fishers and that can be used to provide valuation of these benefits for the broader economy
