Effect of a strain of Lactobacillus used as probiotic on the biological parameters of tilapia (Oreochromis niloticus)
Keywords:animal performance, olive pomace, probiotics, tilapia
Aquaculture is among the fastest growing sectors in agriculture. Freshwater and marine aquaculture production has increased remarkably recently as did the growing demand for seafood. A study was conducted for 15 days and performed on Oreochromis niloticus fry aiming to assess the effect on animal performance of a Lactobacillus strain used as probiotic incorporated in a diet formulated for tilapia fry. The parameters measured were daily live weight gain, standard length, fork length and survival rate. Our results showed that overall individual average weight gain as well as survival rate were significantly higher for animals supplemented with probiotic when compared to control animals. Longer lasting experiments are required to confirm these results.
