Need

In intensive aquaculture systems oxygen supplementation is necessary to prevent hypoxia; however, oversupply can hyper-saturate systems causing gas bubble disease. Oxygenation in aquaculture, fish holding and transport systems using standard technologies is extremely inefficient; standard oxygen transfer efficiencies (SOTE) are estimated at between 2 and 6% per m submergence for coarse and fine bubble diffusers, respectively, at standard conditions of 0 ppt salinity and 20 °C. Advances in the efficiency of gas–liquid phase processes has seen the emergence of nanobubble technologies producing ultrafine bubbles (⌀ 1 µm). The advantage of nanobubbles over larger micro/macrobubbles is that they are neutrally buoyant, negatively charged and can remain within the water column, potentially for weeks. Nanobubble technologies now have a demonstrated application across a broad variety of industries including wastewater treatment, biomedical engineering, gas and oil industry, agriculture, and the food industry. Surprisingly, outside of Japan, there has been little research on the application of nanobubble technology to the aquaculture sector. Nanobubble technology can potentially improve oxygen delivery systems for fish stock and water treatment in aquaculture systems, improving the nitrifying capacity of biofilters and efficiencies in fractionation units. However, there are currently no reliable studies demonstrating the efficacy of nanobubble technology, nor any assessment of the potential health impacts on fish in aquaculture systems. We have undertaken a preliminary pilot trial with encouraging results. Oxygenation was applied to a recirculating aquaculture system via nanobubble injectors for 10 days and fish (yellowtail kingfish) were observed to feed and behave normally when compared to a control group. Before this technology can be considered for broader adoption, a thorough long term investigation needs to be undertaken to assess the long term health effects on fish stock held in nanobubble oxygenated water and the suitability for application of this technology to the aquaculture industry.

Objectives

1. To demonstrate the efficacy of nanobubble technology for use in finfish aquaculture by:i) assessing the health, growth and feed conversion efficiencies of fish cultured in a recirculating aquaculture system at different temperatures, salinities and stocking densities exposed to nanobubblesii) determining the effect of nanobubble oxygenation on waste water treatment efficiencies in a recirculating aquaculture system.iii) providing a preliminary cost benefit analysis on the implementation of nanobubble aeration to an aquaculture system

Summary

Nanobubble (NB) technology, i.e. the production of ultrafine bubbles with diameters <1 µm, is an emerging field which has the potential to greatly improve oxygenation efficiencies in aquaculture production. Before this technology can be considered for adoption by the aquaculture industry, a thorough assessment of the health and growth effects on fish stock held in NB oxygenated water is required. Three trials were conducted to compare NB technology with conventional oxygenation setup (ceramic diffusers and air stones, oxygen gas and air) in a recirculating aquaculture system (RAS) under a number of different aquaculture scenarios testing i) stocking density, ii) salinity, and iii) temperature.

Need

It is very clear that fishing-technology research to improve resource harvesting is a priority need for the future sustainability of fish trawling in Australia. The issue is quite poignant, considering that over the past 15 years, there has been a massive reduction in the total number of trawlers in Australia, and lower profits among remaining operators struggling to remain viable. Innovative modifications and refinements to existing systems that improve selectivity and reduce environmental impacts and costs are an urgent priority to ensure economic viability. Such developments are difficult to achieve by individual fishers without quality research, development and extension that is adequately resourced.

More specifically, there is a clear need to maintain progress towards developing innovative, high-priority technological modifications to fish trawls in the CTS and GABTS that mitigate sustainability issues while maintaining target catches at existing levels. Equally important, ratified designs then need to be tested across fleets to encourage adoption and refinement as a precursor to eventual legislation. Ultimately, satisfying these needs will contribute towards improving the social licence and economic return of trawl fisheries in the SESSF, while helping to ensure their ongoing sustainability and address what remains one of the most controversial issues facing bottom trawling.

Objectives

1. Review the available domestic and international literature and data, and consult with a project stakeholder committee (comprising representatives of the CTS, GABTS, NSW PFA and AFMA) to prioritise modifications to be formally assessed for their utility in minimising bycatch, while maintaining target catches among trawls used in the CTS and GABTS.
2. Based on the outcomes of 1 above, assess the utility of existing and new modifications to trawls for minimising bycatch, while maintaining target catches in the CTS and GABTS.
3. By providing strong economic incentives through improved efficiencies, and via applied extension activities, encourage the wide-scale voluntary adoption and ongoing exploration of appropriate best-practice technologies that cumulatively reduce bycatches, while maintaining target catches in the CTS and GABTS.

Summary

This project sought to produce the first-ever review of technical options for improving fish-trawl selectivity around the planet and then use this information to address a deficit in experimental work quantifying the utility of industry-developed and new selective-gear modifications in the Commonwealth Trawl Sector (CTS) and Great Australian Bight Trawl Sector (GABTS) of the Southern and Eastern Scalefish and Shark Fishery (SESSF). The work was completed during a four-year collaboration (from September 2020) between the New South Wales Department of Primary industries (NSW DPI), Fishwell Consulting, the Australian Fisheries Management Authority (AFMA), Commonwealth Scientific and Industry Research Organisation (CSIRO), South East Trawl Fishing Industry Association (SETFIA) and the Great Australian Bight Industry Association (GABIA). Ultimately, by highlighting regional industry efforts and identifying and validating the benefits of new options to reduce one of the most controversial issues facing bottom trawling, the project contributes towards improving the social licence and economic return of trawl fisheries in the SESSF, and supports ongoing Australian research into technological solutions to ensure fishery sustainability.

Summary

This project sought to produce the first-ever review of technical options for improving fish-trawl selectivity around the planet and then use this information to address a deficit in experimental work quantifying the utility of industry-developed and new selective-gear modifications in the Commonwealth Trawl Sector (CTS) and Great Australian Bight Trawl Sector (GABTS) of the Southern and Eastern Scalefish and Shark Fishery (SESSF). The work was completed during a four-year collaboration (from September 2020) between the New South Wales Department of Primary industries (NSW DPI), Fishwell Consulting, the Australian Fisheries Management Authority (AFMA), Commonwealth Scientific and Industry Research Organisation (CSIRO), South East Trawl Fishing Industry Association (SETFIA) and the Great Australian Bight Industry Association (GABIA). Ultimately, by highlighting regional industry efforts and identifying and validating the benefits of new options to reduce one of the most controversial issues facing bottom trawling, the project contributes towards improving the social licence and economic return of trawl fisheries in the SESSF, and supports ongoing Australian research into technological solutions to ensure fishery sustainability.
