Ichthyoplankton and zooplankton samples were collected seasonally from spring 2001 to winter 2002.

The annual average of primary productivity was 0.05 gm/C/m3/day.

The highest recorded abundance of zooplankton was 18122.45 individual/m2 at the Krane station during spring and 4130.06 individual/m2 at the Al-Amaya station during summer.

The averages of total abundance of Icthyoplankton in Krane and Al-Amaya stations were 84.68 larvae/10 m2 and 55.91 larvae/10 m2 , respectively.

The correlation coefficient between zooplankton abundance in Al-Amaya stations was insignificant (r=0.35 P>0.05) while in Krane station was significant (r = 0.77 P<0.05).
