Effects of Probiotic Bacteria on Fish Performance

According to many reports, the beneficial effects of probiotic bacteria on fish have well been documented. Probiotics as an alternative strategy have been suggested to be used as replacement for antimicrobial drugs and growth promoters. In addition, some researchers believe that probiotics have advantages for improving the health of fish in aquaculture and increasing fish performance. Probiotic bacteria can be used in feed and play a beneficial role in the ecosystem of the fish gastrointestinal tract and finally enhance the growth performance and other rearing parameters such as feed conversion ratio, protein efficiency ratio, digestibility and body composition.
