Two distinct site‐specific populations of Diploslomum spp., occurring concurrently in the lens and retina of naturally infected rainbow trout, were different morphologically. They represent separate populations epidemiologically. The lens and retina metacercariae did not differ immunologically when tested by an enzyme‐linked immunosorbent assay against immune rabbit and trout antisera. Antibody titres became positive by September 1982 in a natural population of yearling rainbow trout infected with lens and retina metacercariae and remained positive for at least 8 months. The antibodies formed may offer protection against reinfections with Diplostomum spp. cercariae.
