Stirling Products of Perth, Australia, at the 2008 Annual Meeting of the American Fisheries Society last week announced its beta glucan product, ProVale, successfully inhibits the impact of Loma gill disease, a parasite that infects farmed salmon and trout.

Already available for use with poultry and swine, ProVale works by boosting a species' immune system against various bacterial and viral diseases.

"We have known that the cell mediated immune response of fish is critical for them to defend against microsporidial diseases," says David Speare, project leader. "Having a treatment that augments the immune response is therefore a very logical commercial approach for disease control."

The company is holding discussions related to licensing and distribution agreements for ProVale.

In mid-June, the company announced it had successfully completed ProVale product trials in shrimp, showing that it improves survival rates and overall shrimp yields under stressful conditions.
