title: [Parasites of Salmo trutta L. from the Tirino River. II. Host-parasite interactions of helminth species].
abstract: The hundred and sixteen brown trout (Salmo trutta L.) which were examined for helminth parasites were captured in the River Tirino, (L'Acquila - Italy). Six parasite species (Phyllodistomum simile, Crowcrocaecum testiobliquum, Crepidostomum metoecus, Cyathocephalus truncatus, Truttaedacnitis truttae and Dentitruncus truttae) were recovered. Ecological studies on each helminth species recovered have been carried out analysing the following aspects; the preference of each parasite species for certain microhabitats in the host; the incidence and intensity of each parasitic infection according to sex, age and season.
