The weight gain and feed conversion of frogs feeding in the
vibrating feeder tray was higher than that of animals feeding
in the linear feeder after day 60 of the study period. In ninety
days of experiment, weight gain (240.48 ± 16.49 g), feed conversion
(1.10 ± 0.01) and the specific growth rate (4.85 ± 0.15%/day)
