A groundbreaking study conducted by Flinders University has investigated alternatives to fish oil feed for locally farmed Yellowtail Kingfish.
With rising fish oil prices, Aussie aquaculture operators are looking for sustainable options while also increasing the commercial viability of Kingfish.
Fish oil has traditionally been a key component in aquafeeds, valued for its rich nutrient and fat content, particularly certain omega-3 and fatty acids vital for the health and growth of carnivorous fish.
The research has now found canola oil and poultry oil can be used as potential substitutes.
While both alternatives demonstrated potential benefits, some concerning changes were also noted in the livers of the fish.
Researchers are continuing their work to gain deeper insights into the implications.
