Diplostomum spathaceum larvae (Diplostomosis)(Digenea) in fish
Infection may result in cataract formation within the lens, leading to partial or total blindness. Starvation may cause a significant reduction in condition, or even death. After penetration of the cercariae, lesions may form on the gills, body surface, and fins, which can cause death, especially in young fish, at high infection rates.
