Fish fauna, difference of stable isotope ratio between freshwater and seawater, andtrophic guilds of freshwater fishes were investigated in the lower Geum River. The study was conductedin 2011, and total study area was about 30 km of 20 km upstream and 10 km downstreamfrom the Geum River estuary barrage. Only freshwater fishes were used for analyzing trophicguilds, and discriminant function analysis (DFA) was utilized to reclassify trophic guilds based onstable isotope ratio. Fish fauna in freshwater and seawater areas were entirely different each other,but small number of migratory species such as Coilia nasus and Chelon haematocheilus occurredboth areas. Other species were not collected in the different areas because they did not have physiologicalability to adapt different salinity concentrations. Stable isotope ration of two areas weredifferent considerably due to food sources. Estuary and seawater fishes uptake food sources originatedfrom marine, and freshwater fishes were from freshwater and terrestrial. Some migratoryspecies showed reverse stable isotope ratio. Even though they collected in freshwater, they showedstable isotope ratio of seawater. This is because ecological characteristics of each species. Trophicguilds of freshwater fishes were reclassified by DFA, and showed slight difference with literatures.However, because this result is related with ontogenetic shift of species, more studies are needed toexplain exact and correct trophic guilds. Stable isotope ratio can be changed among regions, seasonsand ontogenetic stage, thus we always consider these aspects when analyzing results to get a rightanswer.
Abstract
Fish fauna, difference of stable isotope ratio between freshwater and seawater, andtrophic guilds of freshwater fishes were investigated in the lower Geum River. The study was conductedin 2011, and total study area was about 30 km of 20 km upstream and 10 km downstreamfrom the Geum River estuary barrage. Only freshwater fishes were used for analyzing trophicguilds, and discriminant function analysis (DFA) was utilized to reclassify trophic guilds based onstable isotope ratio. Fish fauna in freshwater and seawater areas were entirely different each other,but small number of migratory species such as Coilia nasus and Chelon haematocheilus occurredboth areas. Other species were not collected in the different areas because they did not have physiologicalability to adapt different salinity concentrations. Stable isotope ration of two areas weredifferent considerably due to food sources. Estuary and seawater fishes uptake food sources originatedfrom marine, and freshwater fishes were from freshwater and terrestrial. Some migratoryspecies showed reverse stable isotope ratio. Even though they collected in freshwater, they showedstable isotope ratio of seawater. This is because ecological characteristics of each species. Trophicguilds of freshwater fishes were reclassified by DFA, and showed slight difference with literatures.However, because this result is related with ontogenetic shift of species, more studies are needed toexplain exact and correct trophic guilds. Stable isotope ratio can be changed among regions, seasonsand ontogenetic stage, thus we always consider these aspects when analyzing results to get a rightanswer.
