Abstract
Two suprapopulations of monogeneans, one each of Gyrodactylus bullatarudis and G. turnbulli, on two groups of ten experimentally infected adult guppies (Poecilia reticulata) were maintained separately in 50-l aquaria and monitored over 210 days. The G. bullatarudis population had a pattern of initial growth, then a subsequent decline to extinction after 40 days. G. turnbulli, after initial population growth and decline, maintained low-intensity infections (0.33–3.3 parasites/host) on six hosts over 94 days and did not become extinct during the experiment. There were some differences between the host-site specificity of G. bullatarudis and G. turnbulli on adult P. reticulata as compared with previously observed infections on immature fish.
