Abstract
The objective of this study was to clarify the cytogenetic features, including karyotypes, cellular DNA contents and nuclear size of erythrocytes of three species of fish, the black plaice Pleuronectes obscurus (Herzenstein, 1890), the dotted gizzard shad Konosirus punctatus (Temminck et Schlegel) and the perch sculpin Pseudoblennius percoides (Gü

nther), in the coastal area of Jo Island, Busan, Korea. The karyotypes of P. obscurus and K. punctatus both had a diploid number of 2N = 48 and a fundamental number (FN) = 48, with a chromosome formula of 48T. The karyotype of P. percoides had a diploid number of 2N = 46 and FN = 50, with a chromosome formula of 4SM + 42T. No sex-associated heteromorphic pairs were detected for any species in this study.

The variation in the DNA values (P. obscurus = 1.15 pg/nucleus, K. punctatus = 1.56 pg/nucleus, P. percoides = 1.11 pg/nucleus) was positively related to the variation in chromosome FN in fish examined.

The mean major and minor axes of erythrocyte nuclei measured 3.1 ± 0.16 µ
