| 摘 要： | 在半封闭式奥尼鱼养殖池中输入饲料，探索养殖过程中鱼池沉积形成及其主要影响因子。试验结果表明：无论养鱼或不养鱼，投饲或不投饲，各池都发生不同程度的沉积；外源饲料输入量相同时，养鱼池新颗粒物生成量(干重)比不养鱼池大15．63％，而沉积量比不养鱼池小19．49％；无外源饲料输入时，养鱼池的沉积量比不养鱼池大75．76％；养殖系统内养殖对象与其所处环境的相互依存和相互制约对系统新颗粒物生成及沉积具有重要作用。

| Abstract: | In order to explore the sediment formation and its impact factors,feed was thrown in the semi-closed cultured pond of Tilapia fingerlings.The results showed that there was different natural sediment in different cultured pond,which had no relationship to fish and feed.Compared with the none-fish cultured pond,the formation quantity (dry weight) of new particle and the sediment in cultured pond was 15.63% higher and 19.49% lower respectively when same quantity feed was thrown.Without feed thrown,the sediment formation in cultured pond was 75.76% higher than that in the none-fish cultured pond.We suggest that the interaction between the fish and its cultured environment within the culture system plays an important role in the new particle and sediment formation. |
