Sumario:Macrobrachium acanthurus is distributed along the Brazilian coastal rivers and shows potential for aquaculture. This study was carried out to provide information on the reproduction of M. acanthurus in captivity and the influence of unilateral eyestalk ablation. A total of 48 females and 24 males were captured in the Sahy river in Mangaratiba, Rio de Janeiro State. The animals were distributed into twelve 20-liter aquariums, each with two males and four females. Two females in each aquarium were ablated. Every day the occurrence of ovigerous females was checked in each aquarium. The U test (Mann-Whitney) showed a significant difference among laying intervals and the number of hatchings between ablated and non ablated females.
