Need

The need for the project was identified at the Seafood Access Forum meetings in January and confirmed at the meeting in March 2008. The report will be a key input to discussions at the SAF meeting scheduled for 17 June 2008.

Summary

Over the past thirty years, international trade in fish and fisheries products has grown significantly and today over 50 percent of the value of fisheries production and about 40 percent of the live weight equivalent of fish and fish products enter international trade. Around the world, some 200 million people are employed in the fisheries sector – mostly in developing countries. At the same time, all but four of the world’s key fishing regions (about 75 percent of the world’s fish stocks) is harvested at or beyond the regions’ sustainable limits.

The Australian seafood sector now achieves gross production worth in excess of AUD$ 2 billion per annum, generates exports worth in excess of AUD$ 1.5 billion, and employs significant numbers of Australians in rural and regional areas of the country. The sector has the potential to be a much bigger contributor to exports, employment and national wealth provided that Governments in Australia undertake to work more effectively with the seafood industry to reduce or eliminate overseas barriers to Australian seafood exports, develop new ways to produce and harvest seafood at home and take steps to ensure that high quality Australian seafood production can be sustainably maintained over time.

Need

Inconsistent quality of farmed barramundi (pond or recirculation system) in the marketplace has
been identified by ABFA as a major issue causing buyer resistance and negative market impacts.
This is limiting realisation of full revenue return for farmed barramundi. The inconsistency in
quality is mainly associated with the presence of ‘earthy’ or ’muddy’ taints derived from
planktonic and benthic algae (particularly cyanobacteria), fungi and actinomycetes which are
known to produce geosmin (GSM) and 2-methyl isoborneol (MIB). These compounds impart
muddy, earthy, musty odour, detectable by the human palate when present at extremely low
concentrations in water and fish, and not favoured by consumers (Percival et al., 2008).
This project aims to develop an algae-taint production model for recirculation systems. This
innovative approach will provide clear and measurable direction for reducing taint compound
levels through provision of a practical management tool. Its use will significantly improve
knowledge of the balance between water quality, algicide use and purging time and conditions,
and taint variability.
