The purpose of thepresent study was to determine the performance growth and yield of male and female Macrobrachium tenellum, cultured in earthen ponds. A total of 6 earthen ponds containing 1,400±50.0 m2of water and a depth of 0.85 m were used. A total of 19,600 juvenile M. tenellumwere introduced into each pond to a stocking density of 14 org m-2. The final length, final weight, specific growth rate, weekly growth rate and yield presented significant differences (P < 0.05) between sexes, with the males exhibiting higher values of these indicators. The survival rate was higher in females (65.0%). The total yield obtained in this culture reached 1,603 kg ha-1.
