Chromosome number and karyotype of four important Barbus species of Iran were analysed. Thirty individual of B.grypus, 30 from B.sharpeyi, 28 of B.esocinus and 44 of B.pectoralis weret ested. To provide the chromosomal spreads, the kidney and gill arches of fish were sampled according to Bloom & Kligerman (1977). Barbus sharpeyi diploid model of chromosomes was 2n=98 containing 3 pairs of metacentric, 23 pairs of submetacentric,2 pairs of subtelocentric and 21 pairs of acro & telo- centric. Barbus grypus diploid model of chromosomes was also 2n=98. It contains 1 pair of metacentric, 22 pairs of submetacentric, 1 pair of subtelocentric and 25 pairs of acro & telocentric chromosomes. Barbus esocinus diploid model of chromosomes was 2n=98. It contains 7 pair of metacentric, 13 pairs of submetacentric, and 29 pairs of subtelo,acro & telocentric chromosomes. Barbus pectoralis diploid model of chromosomes was 2n=98. It contains 6 pair of metacentric, 16 pairs of submetacentric, and 27 pairs of subtelo,acro & telocentric chromosomes.
