Abstract
Autopsies of Abbottina rivularis from southern Primorye (drainage-basin of Artyomovka River, Razdolnaya River and Khanka Lake) and southern Sakhalin Island (Maloye Chibisanskoye Lake) revealed high indices of diplostomum-infected lenses of these fishes. The metacercariae have been identified as Diplostomum parviventosum Dubois, 1932, D. huromense (La Rue, 1927), D. helveticum (Dubois, 1929), D. mergi Dubois, 1932, Diplostomum sp. The most lenses of parasitized eyes possessed dorsally situated sperical protrusions of the lens capsule ("cyst"). Earlier, this phenomenon was found by Larson (1965) in naturally infected bullheads (Ictalurus). The metacercarial infection level and its dynamics, age-composition of metacercariae in both lenses and "cysts", and "cysts" production are discussed.

Abstract
All 175 ninespine sticklebacks, Pungitius pungitius (Linné), collected from the Belcher Islands were parasitized by Diplostomum spathaceum (Rudolphi) and 43% by Schistocephalus sp. D. spathaceum metacercariae were mostly confined to a dorso-ventral band encircling the lens of the eye, and were concentrated in the anterio-dorsal sector of this band. The central area of the lens was thus relatively free of diplostomula, probably minimizing interference with the vision of the fish. The frequency distribution of D. spathaceum abundance in P. pungitius was closely approximated by a negative binomial, while that for Schistocephalus was best fitted by a Poisson. None of the fish condition factors examined appeared related to the intensity of the parasitic infections.
