Abstract

The parasite fauna of gobiid fish of the Sukhyi Lyman, Black Sea, is described. Seventeen species of parasites are registered in the gobiids in the water body. The marine tubenose goby Proterorhinus marmoratus has the richest parasite fauna (12 species), the grass goby Zosterisessor ophiocephalus has the fewest number of parasite species (5 species). The microsporidian Loma sp. and ciliate Trichodina domerguei are recorded for the first time for gobiids in the north-western Black Sea. The core of the parasite fauna is formed by metacercariae Cryptocotyle spp. The core, secondary, satellite, and rare species in the parasite community of each host are described. Not only marine and brackish water parasites, but also limnetic species, namely metacercariae D. spathaceum, were registered in the Sukhyi Lyman that differentiates it from the many of localities in the north-western Black Sea.

Abstract

Trichodinids (Ciliophora, Peritrichia) of Perccottus glenii (Actinopterygii, Odontobutidae) in Three Ukrainian Rivers. Drobiniak, O., Kutsokon, Yu., Kvach, Yu. — The Chinese sleeper Perccottus glenii Dybowski, 1877 (Actinopterygii, Odontobutidae), alien for Ukrainian rivers, was examined for presence of trichodinids (Ciliopora, Peritrichia). Six species belonging to the genus Trichodina were found: Trichodina acuta Lom, 1961; T. intermedia Lom, 1961; T. mutabilis Kazubski et Migala, 1968; T. nigra Lom, 1960; T. pediculus Ehrenberg, 1838; T. perforata Lom, Golemansky et Grupcheva, 1976. For the first time for Chinese slipper, T. perforata and T. intermedia were recorded. Morphometric data of all found species were compared with those from previous descriptions.
