摘    要:对在不同混养(牙鲆Paralichthys olivaceus、缢蛏Sinonovacula constricta、文蛤Meretrix meretrix)模式下的氮、磷收支情况进行了研究。结果表明:饵料是池塘氮、磷的主要来源,分别占氮总输入的71.6%~87.1%和磷总输入的67.0%~79.3%;由海水带入的氮和磷占氦、磷总输入的10.9%~14.6%和17.0%~20.2%;在氮、磷支出中,收获的养殖生物分别占氮、磷总输入的20.4%~34.1%和15.5%~24.8%,沉积物为氮、磷支出的主要途径,各占氮、磷总输入的69.6%~73.4%和86.7%~93.5%;3种模式下对氮、磷的利用率分别为9.8%~31.1%和5.6%~24.3%。本试验中的最佳养殖模式为牙鲆(小规格鱼)-缢蛏(小规格,高密度),该混养模式产量高,对氮、磷的利用率高,污水排放少。

关 键 词:牙鲆  缢蛏  文蛤  混养  氮磷收支  氮磷利用率

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.
Keywords:Paralichthys olivaceus  Sinonovacula constrieta  Meretrix meretrix  polyculture  nitrogen and phosphorus budget  utilization efficiency of nitrogen and phosphorus
