Abstract: The nitrogen and phosphorus budgets were studied in ponds with different polyculture patterns of Japanese flounder(Paralichthys olivaceus)with constricted tagelus(Sinonovacula constricta)or clam(Meretrix meretrix).Results showed that the feed was the main nitrogen(accounting for 71.6%-87.1%)and phosphorus (67.0%-79.3%)input in the ponds while the marine water supply provided 10.9%-14.6%of nitrogen inputs and 17.0%-20.2%of total phosphorus inputs.In the output items,the biomass harvested comprised 20.4%-34.1%of total nitrogen and 15.5%-24.8%of total phosphorus in the polyculture.There was 69.6%-73.4%of nitrogen and 86.7%-93.5%of phosphorus in the sediments,with the nitrogen utilization efficiency of 9.8%-31.1%and the phosphorus utilization efficiency of 5.6%-24.3%.The polyculture of Japanese flounder(small size)and constricted tagelus(small size;high stocking density)was found to be the optimal polyculture with high yield,high production efficiency of nitrogen and phosphorus and the less effluents.
