Parasitic fauna of sprat (Sprattus sprattus phalericus RISSO, 1826) from the Turkish Black Sea coast

摘要

This study was performed to identify the parasites of sprat (Sprattus sprattus phalericus RISSO, 1826) collected from the Turkish Black Sea coast during September 1990 to January 1992. Ectoparasites were not found. The nematodes, Hysterothylacium aduncum and Cucullanus minutus were observed on the visceral organs of sprat. The prevalence of these parasites was related to sex and sizes offish and season. H. aduncum was more abundant in female fish, and the prevalence was higher in September than in December and January. Fishes were more infested in old ages than the young ones.%Ova je studija provedena da bi se indetificirali paraziti na papalini (Sprattus sprattus phalericus RISSO, 1826) ulovljenoj na turskoj crnomorskoj obali od rujna 1990. do siječnja 1992. godine. Ektoparaziti nisu nađeni. Nematodi Hysterothylacium aduncum i Cucullanus minutus su nađeni na unutarnjim organima. Brojnost ovih parazita povezana je sa spolom, veličinom ribe i sezonom. H. aduncum je brojniji na ženkama, a zastupljeniji je u rujnu nego u prosincu i siječnju. Starije ribe imaju više parazita od mladih.
