Abstract

The reproductive biology of the common pandora Pagellus erythrinus was investigated in the Gulf of Tunis. A total of 807 specimens were collected by bottom trawl on a monthly basis between February 2003 and January 2004. Total length ranged from 7.6 to 28.5 cm. The species was characterized by protogynous hermaphroditism. The overall females-to-males sex-ratio was 2.78. The reproductive season extended from April to October and mainly from May to July as the SST ranged between 16 to 24 degree C. First maturity (L sub(50)) was reached at 14.6 cm total length for females and 15.8 cm for males. The sex reversal took place between 17 and 18 cm.
