摘　　要：为构建大黄鱼生态养殖模式,通过开展海带-大黄鱼间养试验,研究了该养殖模式下海带对大黄鱼网箱养殖区富营养化海水的生物修复效果。通过对生物修复区、非生物修复区和非养殖区的连续定时和定点监测,结果表明间养海带对大黄鱼网箱养殖区的富营养化海水具有明显的修复作用。经过28 d的连续监测,生物修复区的溶解氧(DO)浓度明显高于非修复区,无机氮(IN)、无机磷(IP)浓度均低于非修复区,同时生物修复区的化学耗氧量(COD)达到非养殖区的水平。因此,海带-大黄鱼的生态间养模式能有效降低富营养化水体中的IN和IP,并显著提高DO浓度,改善水质,这将为大黄鱼的健康生态养殖提供参考。In order to establish ecological aquaculture model of Pseudosciaena crocea,a tentative experiment of bioremediation in Pseudosciaena crocea cage-farming areas by the cultivation of Saccharina japonica was employed for reducing the inorganic N and P elements in the nutritionally enriched sea water in Sandu＇ao,Fujian Province. Continuous fixed point and fixed time detection of sea water showed that S. japonica fundamentally repaired the enriched sea water,while the concentration of dissolved oxygen were significantly increased and the inorganic N and P were distantly reduced comparing with the control of non-bioremediation area in the course of experiment. These results suggested that the combination culture of P. crocea and S. japonicawas was an effective and healthy cultivation model for the sustainable aquaculture of P. crocea.
