Résumé

In the period September 1987 to August 1988, hadras (stake traps) and trawls were used to capture Diplodus sargus Kotschyi (Steindachner, 1876) from the sand and rock intertidal of Kuwait Bay. Length frequency analysis showed that recruitment of young of the year took place in March. Gonadosomatic indices revealed that spawning took place between November and March. Protandrous sex reversal took place for the majority of fish in the second year of life, a number of fish did not undergo sex reversal. D. sargus spent its whole life in the bay. The largest fish were markedly smaller than previously reported for the Arabian Gulf.
