Abstract
The morphomeristic features of Gadus macrocephalus was compared using fish samples from Jinhae Bay in the South Sea and Boryeong in the Yellow Sea, Korea. In total, 332 individuals were sampled from 2 locations to investigate the differences in the morphomeristic features and determine applicability of it as a means of stcok discrimination of G. macrocephalus. No significant differences in the number of vertebrae, 1st to 3rd dorsal-fin soft rays, 1st and 2nd anal-fin soft rays, pectoral-fin soft ray, pelvic-fin soft ray, and gill raker were found between two populations from Jinhae Bay and Boryeong. The results of present study revealed that morphomeristic features of G. macrocephalus was not applicable for stock discrimination.
