While some tilapia strains are now being bred to improve their resistance to the bacteria, the need for research into a wide range of methods for combatting its impact is widely accepted.

In a new trial, conducted by a research team from the College of Fisheries at Huazhong Agricultural University in China, researchers have revealed that adding Bacilllus subtilis to tilapia diets can help to mitigate the effects of the Streptococcus.
