Algae fish feed research wins innovation award

Sunshine Coast University research that could increase the sustainability and economics of shrimp and lobster farming has won a 2022 science and innovation award from the federal government.

The Fisheries Research and Development Society award of $22,000 will help continue the research. This involves adding a small amount of algae to the fish food instead of the antibiotics usually used in aquaculture. The research had previously focused on rabbitfish, but will now continue to find applications in other forms of farmed fish and seafood.

“Antibiotic addiction in aquaculture can have serious impacts on the environment and human health, but outbreaks can cost the industry up to $8 billion each year, so a solution must be found,” said Dr. Valentin Thépot, USC researcher and award winner. , who is also the Aquaculture Coordinator at the Anindilyakwa Land Council.

“The industry is already looking for innovative solutions for disease management and inventory welfare that don’t compromise productivity, and we believe we’ve found a promising solution.

“We want to see if the results we’ve seen in rabbitfish and Atlantic salmon will be replicated in high-value Australian aquaculture stocks such as tiger prawns and tropical lobster.”

With aquaculture providing roughly half of all seafood consumed globally, developing a technique to naturally reduce reliance on antibiotics could be a big win for producers and companies looking to cut costs and increase sustainability.

Other winners include researchers studying the smell of smoke in wine and those seeking to improve the nutrition of laying hens.
