In this study, the effects of different diets on growth rates of Gammarus Pontogammarous meoticus were determined. A biomass of 1.5 g Gammarus with an average length of 7 ± 0.25 mm was transferred to the glass aquaria with volume 900 cm3 (volume 2.5 l). The Gammarus were fed with diets include baked potato (treatment 1), 30 percent yeast and 70 percent potato, (treatment 2), 50 yeast percent and 50 percent potato (treatment 3), no feeding (treatment 4) at rate of 6 to 7 percent of total biomass for 45 days. Results showed that the total production rate (adult and baby), specific growth rate and population doubling time were significantly high in treatments 2 and 3(P > 0.05). The biomass and daily growth rate were significantly higher than yeast fed Gammarus (P> 0.05). Additionally Gammarus in treatment 3 had the highest food conversion ratio. The results of the present study showed that the administration of yeast in diet can improve Gammarus growth rate under culture conditions.
