| 摘 要： | 在水螅的培养中,常出现食物缺乏。为了获得替代食物,比较水螅对一些常见肉类的捕食行为。结果表明,水螅对蚯蚓肉、虾肉、鱼肉、鸡肉、牛肉和猪肉均能捕捉,对各食物的捕捉比例无显著差异;但水螅对食物的摄食比例在食物类型间存在显著差异,对虾肉较为偏好。可选择虾肉作为培养时的替代食物。

| Abstract: | Food is always scarce when hydra was cultured, In this article, in order to obtain the substituting food for hydra, the feeding behaviors of hydra were compared. The results showed that hydra could catch meats of earthworm, shrimp, fish, chicken, beef and pork. There was no significant difference in the frequency when hydra caught those foods. But the eating frequencies of hydra to those foods were significantly different. Hydra prefers shrimp meat. When the food is scare during culture, the shrimp meat might be selected as a substituting food. |
