Notes:
A total of 2,851 fishes belonging to 34 species and weighing 177.15 kg were caught between July 1983 and June 1984 near Kohr al-Zubair in the northwestern Arabian Gulf, using four types of fixed gillnets with different mesh sizes. Four species (Thryssa hamiltoni, Liza macrolepis, T. mystax and Nematalosa nasus) formed 82.1% of all fish while 3 species (L. macrolepis, T. hamiltoni, Pomadasys argenteus) comprised 50.3 % of the total wet weight. The abundance of species was highest during autumn and spring, clearly reflecting the high values for the diverse indices during these periods and indicating the differing biological fish utilization of Kohr al-Zubair. The high positive correlation of temperature to number of species played an important role in this abiotic factor of fish migration to and from Kohr al-Zubair. Quantitative clustering of common fish species based on individual samples showed six distinctive groups. Group I included four resident species, while groups II-VI comprised mainly seasonal species that entered the Kohr area during either warm or cold seasons.
