Abstract:
The fish assemblages of Lesser Zab river was examined to establish a base line
ecological data to be compare future situation and any present disturbance or anomaly
from base line. The fish assemblages were divided according to their spatial occurrence to
five groups. Generic and species names were revised to their current status. Synonym
species were combined together and their numbers were added to the original. The most
abundant species was Alburnus mossulensis, followed by Acanthobrama marmid and third
class Cyprinion macrostomum but slightly different in the three river zones. Diversity,
evenness and richness of Lesser Zab river in general were 2.40, 0.72 and 3.63 respectively,
impaling a prosperous environment. Upper part of Zab was 1.89, 0.65; 2.72, Dokan 1.59,
0.89 and 1.08 lower part of Zab 2.25, 0.71 and 3.61. Similarity between Upper and Lower
parts Zab 71% and 55.5% and lower values with Dokan reservoir was according Bray,
Curits and Jaccard indices respectively, Indicating spatial species difference accordance
with water current and bed nature of Lesser Zab, certain species were chosen as zone
indictor, upper part of Zab Barbus lacerta and Glyptothorax spp., Dokan reservoir Barbus
escocinus Lower part of Zab Barbatula frenatus and Capoeta barrosis.

Key word: Occurrence, relative abundance, ecological indices, fish, Lesser Zab river, Kurdistan
region, Iraq
