The metaphase chromosome was obtained from the fin and its healing hyperplastic tissue of one-year old fish, by hot air drying methods. The karyotypes were examined. The results showed that there were 48 chromosomes in diploid and their karyotype formulae was 2n=4M +10SM + 32ST +2T. Heterotypic sex chromosome was not found since the number of the tested fish was limited and all the young fish were physiologically female.
