| Hatching of eggs of <i>Anguillicola crassus</i> was studied at temperatures between 5 and 30°C. Hatching occurred between 10 and 30°C and the incubation time was inversely related to temperature. Survival, spontaneous and excitatory rate of activity of 2nd-stage larvae of <i>A. crassus</i> were also affected by temperature. The percentage of larvae eaten by <i>Paracyclops fimbriatus</i> was not always influenced by the activity of the larvae. Penetration efficiency into the haemocoel of the intermediate host was highest for freshly hatched larvae and declined gradually with age. Completely non-active larvae were still able to penetrate, although penetration efficiency was lower. |

| The host specificity and population dynamics of <i>Anguillicola crassus</i> in a number of paratenic hosts were investigated. Various freshwater fish species were sampled monthly (March 1990 to March 1991) from the Kolenhaven (Albertcanal, Genk, Belgium) and examined for L<sub>3</sub>-larvae of <i>Anguillicola crassus</i>. Sixteen species were found to be infected: all the physoclist species examined (<i>Gymnocephalus cernua, Lepomis gibbosus, Ictalurus nebulosus, Stizostedion lucioperca, Gasterosteus aculeatus, Oreochromis niloticus</i> and <i>Perca fluviatilis</i>) and those physostome species of which a sufficient number could be examined to detect the infection (<i>Gobio gobio, Leuciscus... |
