This preliminary survey investigated lake Yong-rang on the east coast of Kangwoondo province, Korea, for the purpoae of studying primary productivity of the lake. The field studies were carried out in the summer of 1966, and dissolved oxygen was measured by Winkler's method. From the standpoint of primary productivity, the result of this survey indicated that the lake is mesotrophic type, and the lake being brackish water is often influenced on its metabolism by sea water flowing into it. Therefore, it is believed that the tide becomes the limiting factor of primary production.

The phyto and Zooplankton communities were investigated in the Daechung reservoir lake. It is the general trends of water conditions and plankton flora conserned to become Mesetrophy and early stage of eutrophication. The apeared dominant species of plankton communities were, Crytomonas sp., Eudorina elegans, Microcystis aeruginosa, Anabaena macrospora, A. spiroides, Melosira granulata, M. granulata var. angustissima, M. islandica, M. italica, M. varians, Fragilaria crotonensis, Asterinella formosa, A. gracillima, and Scenedesmus bijuger most of which wre indicator of β-mesotrophy or α-mesotrophication. The reserver were caused by eutrophied at high rate netcage-type fishfarms within the lake basins, at the resently as other ones.

The studies of typical freshwater stream of Jindong which was situated at the upper basin of the North Han River. Total species of collected fishes were 17 species, 8 families and than 10(58.8%) endemic species of Korea, In this study, we added 3 species of Ladislavia taczanowskii, Cottus poecilopterus, and Cobitis rotundicaudata to previously reported lists of the fish communities in the Jindong stream, The fauna of fishes in the Jindong stream were divided into four groups:(1)Brachymyatax-Moroco (2)Ladislavia-Moroco (3)Cobitis-Zacco and (4)Zacco-Moroco which was formed continuous communities. Especially the dominant species collected in the upper sites was Moroco Kumgangensis, and down stream(st.9,10,11), Ladislavia taczanowskii and Cobitis korennsis. The viewpoint of food habit, such as herbivores, canivores and omnivores were contributed to the suitable ecological niche.
