Resumo: | The host specificity and population dynamics of &lt;i&gt;Anguillicola crassus&lt;/i&gt; 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&lt;sub&gt;3&lt;/sub&gt;-larvae of &lt;i&gt;Anguillicola crassus&lt;/i&gt;. Sixteen species were found to be infected: all the physoclist species examined (&lt;i&gt;Gymnocephalus cernua, Lepomis gibbosus, Ictalurus nebulosus, Stizostedion lucioperca, Gasterosteus aculeatus, Oreochromis niloticus&lt;/i&gt; and &lt;i&gt;Perca fluviatilis&lt;/i&gt;) and those physostome species of which a sufficient number could be examined to detect the infection (&lt;i&gt;Gobio gobio, Leuciscus cephalus, Chondrostoma nasus, Leuciscus leuciscus, Alburnus alburnus, Leuciscus idus, Scardinius erytrophthalmus, Rutilus rutilus&lt;/i&gt; and &lt;i&gt;Tinca tinca&lt;/i&gt;). There were large differences in prevalence among the fish species examined but generally the prevalence was higher in physoclist fishes and was highest in &lt;i&gt;G. cernua&lt;/i&gt; (96%). In 4 species there was a significant positive correlation between the fish length and parasite abundance. The percentage of grown larvae varied among fish species, being lowest in &lt;i&gt;G. cernua&lt;/i&gt; and highest in &lt;i&gt;P. fluviatilis&lt;/i&gt;. No clear seasonal incidence cycle was observed.
