摘    要:在10个水族箱(53cm×24cm×23cm)中各放养中国对虾(Penaeuschinensis)4尾,混养孔石莼(UluaPertysavar)0、4g、6g、8g和10g,采用投饲精养.结果表明,孔石莼能有效吸收N、P营养盐,提高对虾对饲料中氮的利用率(42.7%~212.9%),水质状况也优于单养对虾.混养的综合养殖指数高于单养对虾.对虾密度为320-480g@m-3,石莼密度为400~600g@m-3时,可以进行免充气养殖.

关 键 词:石莼  中国对虾  混养  密度  水质  成活率  生长  氮利用率

Abstract:Polyculture of Chinese shrimp ( Penaeus chinensis ) with various biomass of Ulva ( Ulva pertusavar ) was conducted in ten aquaria of each 53cm @ 24cm @ 23cm from July to September in 1998. The results showed that Ulva could absorb N and P nutrients and improve water quality by decreasing the nitrogen and phosphorus loading and increase dissolved oxygen levels in the polyculture systems. The shrimp had total N and P utilization rates of 42. 7% - 212. 9% higher in the tanks with Ulva than those in the monoculture system. When the densities of shrimp and Ulva were optimal ( 320- 480 g#m- 3 and 400- 600 g#m- 3) , the oxygen produced by Ulva was suff icient for shrimp. s need without extra aeration.
Keywords:Ulva pertusavar  Penaeus chinensis  polyculture  water quality
