Abstract

Resoult of the study on 10 fish species of chromosomes (CS) standard included Hampala disparMystacoleucus lepturus, Hypsibarbus malcomi, Esomus metallicus, Poropuntius laonsis, Cy-clocheilichthys apogon, Rasbora cf. atridorsalis, Systomus rubripinnis, Barbonymus altus, Mystac-oleucus obtusirostris. There were the objective to study the number, patterns and karyotype of CS 10 fish species by using conventional staining techniques. The results demonstrated in the study were as follows in 10 fish species showed the number of diploid chromosomes 2n = 50 rods of each spcies. The karyotypes of CS as followed in H. dispar had metacentric 5 pairs, sub-metacentric 5 pairs, acrocentric 3 pairs, telocentric 5 pairs and the number of chromosomes arms (Fundamental Number “NF”) was 90 bars. The karyotyping of CS in M. lepturus was metacentric 4 pairs, sub-metacentric 2 pairs, acrocentric 4 pairs, telocentric 15 pairs and NF was 70 bars. Futhermore, The karyotyping of CS in H. malcomi consisted metacentric 3 pairs, submetacentric 3 pairs, acrocentric 6 pairs and 13 pairs of telocentric chromosomes, the NF was 74 bars; which of the results of E.metallicus found that three types of karyotypes consisted as metacentric 7 pairs, submetacentric 5 pairs, acrocentric 13 pairs, and NF was 100 bars. Moreover, in the karyotype of P. laonsis had metacentric 7 pairs, submetacentric 3 pairs, acrocentric 6 pairs, telocentric 9 pairs and NF was 82 bars. In the karyotype of C. apogon included metacentric 6 pairs, submetacentric 5 pairs, acrocentric 5 pairs, telocentric 8 pairs and NF was 88 bars. In Rasbora cf. atridorsalis consisted metacentric 5 pairs, submetacentric 4 pairs, acrocentric 3 pairs, telocentric 13 pairs and NF was 74 bars. The karyotype of S. rubripinnis was metacentric 2 pairs, sub-metacentric 10 pairs, acrocentric 2 pairs, telocentric 11pairs and NF was 78 bars. In the B. altus found that 2 pairs of metacentric, sub-metacentric 10 pairs, acrocentric 2 pairs and 11 pairs of telocentric and 78 bars of fundamental number; finally, the karyotype of M. obtusirostris was metacentric 4 pairs, submetacentric 6 pairs, acrocentric 2 pairs, telocentric 13 pairs and NF was 74 bars.
