Increased fish mortality due to infections has forced most farmers to resort the use of chemotherapeutic agents especially antibiotics. The continued use of these drugs in aquaculture is becoming limited as pathogens develop resistance and infer unpredicted long term public health effects. More research efforts are building to identify alternative disease prevention methods, among which the use of probiotics has been... Read more.
