Abstract
The seasonal variations in species composition and abundance of the fish assemblage were studied in the rocky subtidal habitat around the Jam-do, Jinhae. Fish samples were collected monthly from September 2007 to July 2008 using a pot. During study, a total of 48 fish species belonging to 24 families were collected. The dominant species were Sebastes longispinis, Pseudoblennius cottoides, Sebastes inermis, Rudarius ercodes, Ditrema temminckii, Ernogrammus hexagrammus, which accounted for 71.0% of the total number of individuals collected. The number of species, number of individuals, biomass and diversity greatly fluctuated showing a peak in the number of species, number of individuals and species diversity in autumn, whereas the biomass was the highest in spring. Abundance of dominant species varied with season. S. longispinis was abundant during spring and summer, while the abundance of P. cottoides was higher during autumn and spring. S. inermis occurred with high number in September, December and May, whereas R. ercodes occurred exclusively during autumn.
