The purpose of the present 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 m2 of water and a depth of 0.85 m were used. A total of 19,600 juvenile M. tenellum were 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 .
