氮磷收支,nitrogen and phosphorus budgets
1)nitrogen and phosphorus budgets氮磷收支
1.niloticus,stocked and captured in enclosures was low innitrogen and phosphorus budgets.niloticus）混养海水围隔氮磷收支的研究结果表明，投饵和施肥是围隔氮磷收入的主要来源，而底泥积累则占氮磷支出的绝大部分，放养的苗种和收获的养殖产品在氮磷收支中所占的比例很小；对虾与非鲫混养较单养对虾能够明显提高对饵料和肥料中氮磷的有效利用率，但由于混养时投饵和施肥量较单养时多，混养与单养在饵肥料中损失的氮磷量和围隔底泥中氮磷积累量方面实际差别并不大。
