| This study was to investigate the habitat conditions and growth of right eye flounder (Kareius bicoloratus) in the Saemangeum Reseorvoir during 1995$sim$2007. The planktonic larvae of K. bicoloratus appeared in early March, and then the juveniles started the benthic life in the tide-pools inside the reservoir, being 1.5$sim$2.5cm in total length in early April and 6.0$sim$7.2cm in mid-July. This species was not collected in the tide-pools after July, indicating that the juveniles began to move to outer seas for growing. When the tide barrier of Saemangeum was constructed, the juveniles of K. bicoloratus decreased as the tidal pools were covered continuously, then they could not be collected after 2005. Thus, it is concluded that the environmental change has taken important influence on distribution and spawning of K. bicoloratus since the reservoir was constructed. |
