| 摘 要： | 通过实验室小试研究濒临灭绝物种螺蛳(Margarya melanioides)对舟形藻(Naviculaceae sp.)、菱形藻(Nitzschia sp.)、孟氏颤藻(Planktothrixmougeotii)以及四尾栅藻(Scenedesmus quadricauda)4种典型附着藻类的摄食探讨其摄食生态学特性,调查海菜花(Ottelia acumiuate)养殖塘中藻的群落结构及水体的pH值、光照、溶解氧(DO)、温度等环境,从摄食生态学角度分析,探讨螺蛳在洱海流域恢复的可行性。摄食实验结果显示:螺蛳对实验选取四种藻摄食率关系为舟形藻菱形藻孟氏颤藻四尾栅藻。对舟形藻摄食的影响因素研究结果表明在温度为25℃时其摄食强度最大,摄食率(IR)为(2.19±0.16)mg个~(-1)d~(-1);螺蛳在光照为0-100001x的范围内均有较强的摄食活动,摄食活动最适宜的光照强度区间为1000-20001x,摄食率IR均达到3.0mg个~(-1)d~(-1)以上;溶解氧DO对其摄食活动影响显著,当DO大于3.6mg/L时螺蛳摄食活跃,低于1mg/L时螺蛳基本停止摄食;螺蛳摄食率大小跟螺蛳重量呈显著负相关P0.05。洱海流域海菜花塘水体的调查结果得出海菜花塘的pH值、光照、DO、温度以及藻等环境因子均适合螺蛳生存繁衍,可通过构建海菜花湿地来实现螺蛳的保种与扩增恢复。
