Abstract :
Effects of the probiotic bacteria, Pediococcus acidilactici on growth performance of the Convict Cichlid fish (Amatitlania nigrofasciata) were examined. The main aim of the research was to examine the related effects of the probiotic P. acidilactici to increase the production of ornamental fishes. 150 fries of the Convict Cichlid fish were fed for 60 day in 15 groups (1 control and 4 treatments, each with 3 replicants) with dry food containing the probiotic P. acidilactici (0, 0.5, 1, 1.5 and 2 gr/kg). Biometric features (standard length and body weight) were measured every two weeks and growth and feeding indices were conducted at the end of the period. Compared with the control group, the results showed better growth performance in the treatments and the best results achieved in the group 4 with 2 mg prebiotic per kg dry feed. The recent research proposed the use of the probiotic P. acidilactici to enhance ornamental fish production in hatcheries of the convict cichlid fish.
