| 英文摘要 | The use of bivalve aquaculture to mitigate eutrophication in coastal waters has been proposed for years. As nitrogen overenrichment is usually accompanied by comparative shortages in silicate and phosphate, bivalve cultivation integrated with artificial fertilization may exhibit better nitrogen removal performance than bivalve cultivation alone. During a 15-day mesocosm experiment in a nitrogen-eutrophicated, phosphate-limited coastal pond, the nitrogen fixation in oyster tissue under rice husk ash (RHA) 1 fertilized conditions was 10 times higher than that in the oyster-only treatments with the same density. Meanwhile, the concentrations of dissolved inorganic nitrogen (DIN) and particulate nitrogen (PN) in the combined oyster-fertilization treatments decreased by 87.0% and 57.2%, respectively. Compared with the RHA fertilization treatments, the net DIN consumption was significantly lower and decreased with the oyster density in the oyster-only treatments. The dissolved N/Si ratio decreased from 1.44 to 1.01 and 0.93 in the control and fertilization treatments, respectively, whereas in the oyster-only treatments, it increased to 3.74 at low density and 29.15 at high density. Our results indicate that oyster cultivation can stimulate the regeneration of nitrogen in dissolved forms and intensify relative silicate shortages. The integration of RHA fertilization mediated silicate shortage and helped maintain a balanced dissolved N/Si ratio. Moreover, the combined oyster-RHA fertilization enhanced nitrogen removal efficiency and biomass accumulation and increased the feasibility of oyster cultivation as a cost-effective nitrogen reduction measure.
