Summary

This audit considered a number of opportunities to reduce heating energy consumption in a prawn farm with irrigation and ventilation improvements already implemented. The case study highlights energy savings of 6.5% in the site total energy consumption, corresponding to 12% of hatchery energy use, by covering heated hatchery tanks and heat recovery systems with an average payback or around 3.5 years, annual saving of almost $9,500 and emission reductions of 62.9 t CO2-e per year.

Farm Profile

Located near Ilbilbie in Central Queensland, this prawn farm operates 33 saltwater ponds with a total pond area of approximately 33 hectares and a volume of 495,000m3. Development is currently underway for the introduction of new ponds to bring the total to 47. The site produces an average of approximately 450 tonnes of whole fresh prawns each year and includes its own hatchery containing approximately 135 open tanks.
