| 摘 要： | １９９５年６～１０月和１９９６年６～８月对不同单养和混养海水实验围隔的水化学研究结果表明：围隔中盐度、总氮、总磷和化学耗氧量（ＣＯＤ）在雨季前逐渐升高，进入雨季后降低；投饵养殖时围隔中磷浓度较低氮浓度较高，其中混养中国对虾和台湾红罗非鱼的围隔活性磷（ＰＯ４－Ｐ）浓度相对较高，混养对虾与菲律宾蛤仔的围隔氨氮（ＮＨ３－Ｎ）浓度较高，投铒兼酌情施肥养殖时围隔中氮浓度较低磷浓度较高，其中混养中国对虾与缢蛏

| Abstract: | Two enclosure experiments were carried out from June to October in 1995 and June to
August in 1996 to evaluate the effect of different types of monoculture or polyculture on water
chemistry in enclosures .The results showed that concentration of total nitrogen and total phosphorus ,
chemical oxygen demand , and salinity increased before rainy season then dropped rapidly after rain .
When only feed was adopted , the concentration of reactive phosphate and total phosphorus was
relatively low and the concentration of nitrite , nitrate , ammonia and total nitrogen was high .When
both feed and fertilizer was provided , the concentration of nitrite , nitrate , ammonia and total nitrogen
was low and the concentration of reactive phosphate and total phosphorus was high .Concentration of
reactive phosphate was usually higher in enclosures stocked with hybrid tilapia , Oreochromis
mossambicus ×O .niloticus , while the concentration of ammonia was higher in enclosures stocked with
Ruditapes philippinarum or Sinonvacula constricta .Chemical oxygen demand in present experiments was
not as high as that usually reported in freshwater fishponds or seawater shrimp-ponds , and much lower
in those enclosures stocked with bivalves .Present experiments suggest that water chemistry in
experimental enclosures was mainly dependent on daily management activities such as feeding and
fertilizing , and partly influenced by stocked shrimp , tilapia and bivalves at the same time . |
