Decapod Larvae Monitoring Programme

A b s t r a c t: Plankton samples were taken monthly at seven stations in the Dawhat ad-Dafi bay system and off Abu All Island since November 1992. Significant differences were observed in composition and abundance of decapod larvae between the stations in the bay system and off the open coast. A clear seasonality in the occurrence of decapod larvae was noticed, with a sharp decline in abundance in December and an increase in March/April. This fluctuation coincides well with the water temperature curve.
