| Abstract;The artificial reef of concrete blocks was placed on the sandy silt bottom about 4m in depth on the coast of the brackish Lake Nakaumi. A successional survey of animals and plants was carried out on the artificial reef for about two years. Seaweeds have not grown well without Ulva sp. and smaller species during the survey period. Balanus spp. dominated on the artificial reef past three months. Afterward, Mytilus edulis increased and dominated twelve months later. In summer, they died all together. The main animals on the artificial reef were B. spp., M. edulis, Limnoperna fortunei, and Anomia chinensis, which were common species in Lake Nakaumi. The biomass was 24124.5g wet weight/m'2' nineteen months later, and after that it had decreased. Brackish fishes gathered to the artificial reef in summer. (author abst.) |
