Abstract
The seasonal and interannual variation in the species composition and abundance of the fish assemblage were studied. Fish samples were collected seasonally over 4 year (2005 to 2008) using pots in the southern coast of East Sea. During the study period, a total of 32 fish species belonging to 24 families were collected. The dominant species were Conger myriaster, Paracentropogon rubripinnis, Liparis tanakae, Parapercis sexfasciata, Eptatretus burgeri and Clupea pallasii pallasii, which accounted for 91.9% of the total number of individuals collected. The number of species, number of individuals, biomass, and diversity fluctuated with season. The peak number of species and number of individuals occurred were in August 2008, whereas the biomass was the highest in August 2005 and diversity was in May 2008. The abundance of dominant species also showed some seasonal and interannual changes. A one-way analysis of similarity (ANOSIM) showed that the fish assemblage in 2008 was significantly different from those of 2005, 2006 and 2007, whereas there was no significant difference among seasons over 4 years.
