福建漳浦前亭综合养殖系统 1 #池的主养种为菲律宾蛤仔 (Ruditapesphilippi narum)和泥蚶 (Tegillarcagranosa) ,搭养种为日本对虾 (Penaeusjaponicus)和长毛对虾 (Penaeuspenicillatus) .2 #池的主养种为菲律宾蛤仔 ,搭养种为日本对虾 .1 999年 8月至 2 0 0 0年 7月的周年跟踪调查结果表明 :这两口综合养殖池 9个水质理化因子 (水温、透明度、盐度、氨氮、亚硝酸氮、硝酸氮、活性磷酸盐、pH值、化学需氧量 )和2个沉积物指标 (有机质、硫化物 )的测值大多数符合养殖标准 .1 #池COD、有机质和硫化物的测值大多数比 2 #池的低得多 ,这表明不同综合养殖系统的生态环境条件不同 ,养殖效益也不同 .Investigation of two composite culture systems in Qianting,Zhangqu, Fujian was made from August 1999 to July 2000. In 1 # pond, Ruditapes philippinarum and Tegillarca granosa were main cultured strains, Penaeus japonicus and Penaeus penicillatus were minor cultured strains. Ruditapes philippinarum was main cultured strain and Penaeus japonicus was minor cultured strain in 2 # pond. The results of water quality (water temperature,transparency,salinity,ammonia-N,nitrite-N,nitrate-N,phosphate-P,pH,Chemical Oxygen Demand) and sediment (organic matter,sulphide) in these two composite culture systems showed that the vast majority of these environmental factors were in accord with the cultured demands. In 1 #pond, the concentration of COD and the contents of organic matter and sulphide were more lower than 2 # pond, so the culture benefit of 1 # pond was better than 2 # pond.
