The investigation of mollusks and the swimming-out of pre-larva fish from mussels in the Lake Uiam was carried out from March to November in 1981. The results of these investigations were summarized as follows: 1. The dominant species of mollusks living in the Lake Uiam is Corbicula fluminea. 2. The size of Semisulcospira gottschei and Corbicula fluminea is larger in the southern parts of the lake and gets smaller toward the north of the lake. 3. Semisulcospira gottschei and Corbicula fluminea are collected from all areas in the lake, regardless to the soil texture and water depth. 4. The number of species of mollusks in the lake is two classes, three orders, seven familes, including sixteen species. 5. The swimming-out rates of pre-larva fish are 43.9%, 4.5%, and 1.9% in Anodonta fukudai, Lanceolaria acrorhyncha, and Unio douglasiae respectively. 6. The authors confirmed one more mussel(Lanceolaria acrorhyncha) from which pre-lava fish have swum out. 7. The swimming-out of pre-larva fish from mussels takes more than a month.

The ephemeropterans such as Epeorus pellucidus, Uracanthella rufa and Drunella aculea were dominated in station 1. It was generally showed the stable aquatic communities with low dominance index values throughout the year in station 2. The first dominant species in station 3 were all mayflies with the average DI value of 0.38. The first dominant species of Uracanthella rufa known as relatively tolerant species in station 4. A crustacean species Gammarus spp. have frequently occurred as the 1st or 2nd dominant species in station 5. Limnodrilus socialis, and Chironomus spp. were dominated in stations 6 and 7. Station 1, 2 and 3 were classified as oligosaproblic status according to their average diversity index values ranging from 3.46 to 3.52. Station 7 showed α-mesosaprobic water condition with the overall average diversity value of 1.26. In general, the equitability and species richness values in the same sampling areas had close relations with their diversity values. The dendrogram drawn by dissimilarity values among 7 sampling sites indicates that the macrobenthic communities were divided into 3 groups: stations 1, 2, 3 and 4: stations 6 and 7; and station 5 alone.
