The feeding relationships of the fish community in the inshore waters of Khor Al-Zubair (North-West Arabian Gulf) were investigated from June 1986 to June 1987. On the basis of stomach content analysis of the 16 commonest species, three major food types (bivalves, crabs and shrimps) were found. The degree of dietary overlap among the species studied was approximately 9.6%, and this is similar to those found for other marine fish communities. Diet similarity between each pair species was calculated. The results suggest that these fish may be in direct competition for food.
