Fresh By Design is working with the NSW Department of Primary Industries and Patterson Building Group to install brand new recirculating aquaculture systems at the Gaden Trout Hatchery near Jindabyne, NSW. The systems will be used for breeding and rearing of trout species for stocking into local alpine river systems, supporting the local recreational fishing industry. The three systems to be installed will each consist of 4 x 4,000 L square fibreglass tanks, a 22,000 L in-ground concrete sump containing 2.2 m3 of C1 biomedia, a Faivre 40-series drum filter with 63 micron screens, UV sterilisation, a Waterco E600 AFM polishing filter loop, heater-chillers, a Pentair Sparus return pump and OxyGuard Pacific monitoring of temperature, dissolved oxygen and pH.
