Summary:This work aims to verify the reproductive dynamics and growth of the Hoplias aff. malabaricus species in the Taperoá II dam lake (07º11’44”S, 07º13’44”S), located in the basin of the River Taperoá in the Cariri region of Paraiba. Sixty-seven individuals were collected (August-December 2002, January-February, May and June 2003) by means of gillnets and cast nets. The interference of the rain regimen in the reproductive behavior and the structure of growth of the species were observed after the macrocospic analysis of the gonads of the collected units.
