| 摘 要： | 通过在小水族缸中饲养大瓶螺试验，表明：米糠、油菜饼、浮萍等饵料的饵料系数分别为５．５１３、１８．９４８、１４．４１０；使用米糠喂养时仔螺生长速率最快，浮萍次之。养殖水体交接时间间隔过长，水体ＰＨ值和铵氮含量上升，溶解氧浓度下降，大瓶螺对腐败的水体有较强适应能力。

| Abstract: | The studies showing: The fastest growth rate for culture of Ampullaria gigas were use rice chaff,and the lemnaceas took second place. Their food factors were 5. 513 and 14. 410 individuallyYoungAznpu11aria gigas could suit to polluted water body,and water bodies'pH and density of NH4-N increased and it's density of DO declined without water refreshed for long time. |
