  • Species composition and seasonal variation of fish assemblages in Sargassum beds in Gamak Bay was determined using fish samples collected monthly by a surrounding net from October 2008 to September 2009. A total of 21 species, 582 individuals and 5,345.1 g of fishes were collected during the study period and Perciformes accounted for 47.6 % of the total number of species. Takifugu niphobles, Engraulis japonicus and Lateolabrax japonicus predominated in number, accounting for 55 % of the total number of individuals. Higher number of species and individuals occurred in June and in September-October. Species were grouped into three by cluster analysis: A) dominant species such as Leiognathus nuchalis and Takifugu niphobles, B) fish collected mainly in spring such as Sebastes inermis, Chaenogobius heptacanthus, Pterogobius zonoleucus, Pholis nebulosa, and Trachyrhamphus serratus, and C) fish collected mainly in autumn such as Engraulis japonicus, Lateolabrax japonicus, and Hyporhamphus sajori.

  • We determined the influence of Sargassum beds on the water quality in Gamak Bay, Korea. Water temperature and salinity range from 3.3 to $23.4^{\circ}C$ and from 29.6 to 33.7 psu, respectively. Dissolved oxygen was 10.45 mg L-1 in the Sargassum bed and 9.23 mg L-1 in the control. Chlorophyll-a was $3.90{\mu}g\;L^{-1}$ in the Sargassum bed and 2.21${\mu}g \;L^{-1}$ in the control. Chemical oxygen demand were 1.14${\mu}g\;L^{-1}$ in the Sargassum bed and 1.43${\mu}g\;L^{-1}$ in the control. Total nitrogen were 0.038${\mu}g\;L^{-1}$ in the Sargassum bed and 0.067${\mu}g \;L^{-1}$ in the control. Total phosphorus were 0.043${\mu}g \;L^{-1}$ in the Sargassum bed and 0.072${\mu}g \;L^{-1}$ in the control. Multivariate statistical analysis was used to analyze data. Water temperature was highly positively correlated with DO (p<0.01). T-N was highly positively correlated with T-P (p<0.01).
