Karyotype and number of chromosomes of silver carp (Hypophthalmichthys molitrix) were determined by using tissue-squashing method and gimsa staining. In this experiment 80 larvae and 10 fingerlings (weighting 1-8 g) were examined and totally 30 chromosomal slides were prepared. The obtain results indicated that the number of chromosomes in this species was found 2n=48 (with 88 chromosomal arms). Consist of 6 pairs metacentric (M), 14 pairs submetacentric (SM) and 4 pairs of Acrocentric (A). The karyotype formula can be stated as: (6M + 14SM + 4A).
