Karyotype analyses of five species of marine fishes

The karyotype of five species of marine fishes were analysed from metaphase ofspleen, kidney cells or gill tissue by the colchicine - hypotonic - air drying and Giemsa stainingtechnique. Hemitripterus villosus has 46 chromosomes in diploid, its karyotype is 2n =46 =20m+ 16sm + 10t, NF =82;Zoarces elongatus Kner has 48 chromosomes in diploid,its karyotypeis 2n =48 =30m + 14sm +4t, NF =92; Zoarchias microstomus has 28 chromosomes in dip-loid, its karyotype is 2n =28 = 24m +4t, NF =52;Azuma emmnion has 56 chromosomes indiploid, its karyotype is 2n =56 =6m + l0sm +40t, NF =72; Odontamblyopus rubicundus has38 chromosomes in diploid, its karyotype is 2n =38 =20m + 18sm, NF =76.
