【摘要】 对小鞘指环虫、鲢指环虫和河鲈锚首虫行为的研究表明:在寄生状态下,这三种单殖吸虫的活跃性很不一样,而被剥离到清水中之后,其活动性均大大加强.纤毛幼虫孵出后即开始活跃的运动,对水流敏感且对来自宿主鱼和非宿主鱼的组织有相似的趋向反应.更多还原

【Abstract】 The behavior of Dactylogyrus vaginulatus , D. hypophthalmichthys and Ancyrocephalus mogurndae were studied. The three species of monogeneans showed quite dif-ferent activities while attaching on their hosts and increased movement greatly after deprived from the hosts. The ciliated larvae of these monogeneans moved about immediately after hatching and were susceptive to water currents. The larvae showed similar tropism to tissues from their normal hosts or other fishes.更多还原
