Following a successful lab trial last year, SARDI has partnered with Port Fairy abalone farm Southern Ocean Mariculture, Aquafeeds Australia and Tarac Technologies to conduct an on-farm trial of abalone feed made with recycled grape marc.
During the three-month lab trial, greenlip abalone fed the grape marc diet showed a 6 per cent improvement in biomass gain and a 2.9 per cent increase in shell growth rate compared with abalone fed on a commercial diet.
The grape marc-fed abalone also outperformed the other abalone in Food Conversion Ratio.
The group is now in the midst of a six-month farm trial. “They are accepting the food, there’s been no mortalities and they are growing well."
