Seaweed scientist funded to test seaweed feed supplement in shrimp

After testing the supplement in rabbitfish and Atlantic salmon, University of the Sunshine Coast researcher, Valentin Thépot, will test it in shrimp and lobster.

University of the Sunshine Coast (USC) seaweed research that could boost sustainability and cost-effectiveness in prawn and lobster farming has won a 2022 Science and Innovation Award from the Federal Government.

USC researcher and aquaculture coordinator at the Anindilyakwa Land Council, Valentin Thépot, was awarded $22,000 through the Fisheries Research and Development Corporation to continue research that has the potential to improve the $300 billion global aquaculture industry.

Thépot found in early trials that a small feed supplement of seaweed boosted the natural growth in rabbitfish by 19% and immunity by 400%. He said the Federal funding would help the next phase of trials to translate the success to high-value aquaculture.

“Reliance on antibiotics in aquaculture can have serious environmental and human health repercussions, but disease outbreaks can cost the industry up to $8 billion each year, so a solution must be found,” Thépot said.

“The industry is already looking for innovative solutions for disease management and stock welfare that do not compromise productivity, and we think we have found a promising solution. We want to see if the results we saw in rabbitfish and Atlantic salmon will be replicated in high-value Australian aquaculture stock such as tiger prawns and tropical rock lobster,” he said.

USC Seaweed research group leader, Professor Nick Paul, said the award reflected the enormous potential for seaweed to improve Australian industry at a time when commercial research innovation was a core focus for strengthening the economy.

“The project could even have a global impact, given the projected costs of antibiotic-resistant bacteria to the global health care system are up to $1 trillion per year by 2050,” Professor Paul said.

USC's world achievements towards a more sustainable future were recognized last year when the university ranked third in the world in the “Life Below Water” categories of the Times Higher Education Impact Rankings.
