Résumé

Synopsis: The reproductive biology ofSarotherodon mossambicus (Peters), a species exotic to Sri Lanka, was studied in Parakrama Samudra — an ancient man-made lake. Females outnumbered males by approximately 2 to 1, but the predominanace of females tended to decrease with increasing size. Males mature at a length of 27.5 cm and females at a length less than 15.0 cm.S. mossambicus breeds throughout the year with four possible peak periods, which coincide with the tailend of the monsoon and intermonsoon rains. The egg diameter distribution indicates the presence of reserve oocytes and yolked oocytes, the latter falling into a single mode between 1.2 to 3.6 mm. Fecundity varied between 360 and 1775 for fish ranging in length from 20.0 to 31.9 cm and 145 to 538 g in weight. The diameter of nests increased with depth up to 60–65 cm. Nests were not found in depths over 90 cm.
