, 1996 于1990年8月-1992年4月在汉阳县军江渔场采集鳜标本，运用形态学和行为学实验方法研究其侧线管的形态结构和捕食行为反应特性。结果表明，职眶上管、眶下管管腔和神经丘直径最大，部分管道未埋入骨组织中；躯干部侧线管管腔和神经丘直径最小，全部埋人鳞片中；前鳃盖下颌管、眼后管等头部侧线管管腔和神经丘直径介于前二者之间，全部埋入骨组织中。饭测线对头部前上方振动刺激很敏感并可诱导捕食反应；对头部侧面振动刺激反应不强，对躯干侧面和后方振动刺激仅有警戒反应。据此，认为鳜头上部位直径大 ...

, 2006 本研究以长江中下游三个典型湖泊即草型湖泊扁担塘、藻型湖泊东湖和通江湖泊洞庭湖为研究地点，系统开展了底栖动物食物组成和食物网的定量研究。主要研究结果与结论如下： 1．采用胃、肠含物分析法，定量研究了底栖动物的食物组成。结果表明：1）多数底栖动物初级消费者以有机碎屑为食，高营养级种类以无脊椎动物为食。2）同种软体动物幼体与成体的食物组成差异一般较显著。在洞庭湖，小个体动物摄食较多的藻类、轮虫和甲壳动物。3）食物组成的时空动态显著。食物资源的可得性是影响底栖动物食物组成及其时空动态的主要因素。 2 ...
