Resumen:
Hypleurochilus fissicornis is a resident species of the intertidal and subtidal zones of Mar delPlata, Argentina. The specific reproductive biology was studied by means of both microscopicand macroscopic analyses. A total of 212 males and 223 females were analysed. Specimenswere dissected and their gonads and livers were removed. The gonadosomatic and hepatosomaticindexes and the condition factor were calculated on a monthly basis. Hypleurochilusfissicornis breeds in rocky intertidal areas, and exhibits low fecundity with benthic eggsand parental care. Size at first maturity (L50) was estimated at 53.66 and 55.83mm totallength for females and males, respectively. The spawning season takes place betweenDecember and April.
