| A novel or canal-type continuous removal of organic matter (C-CROM) with combined freshwater bivalves (Unio douglasiae and Anodonta woodiana) was developed to improve the water quality (IWQ) of eutrophic reservoirs. The first experiment was performed for 12 days to measure the IWQ using 256 individuals of combined bivalves (ca. 7:3), at the same density that distributed in the collection stream. The second experiment was conducted to evaluate the efficacy of IWQ with the addition of each 30% of two mussels for 14 days. Results indicated that a novel C-CROM significantly decreased suspended solids, chlorophyll-$alpha$, transparency, total nitrogen and phosphorus, and increased ammonium and biodeposition (t-test, P<0.001 for all), while other dissolved inorganic nutrients such as $NO_2$, $NO_3$, and SRP did not change (t-test, P>0.5). Daily IWQ performances of C-CROM with combined mussels was about two times higher to the previous studies using single species where less suspended inorganic nutrients were released except for ammonia. Collectively, a C-CROM is more strategic to the water quality improvement of eutrophic lake. |
