Abstract
Nematodes of the genus Eustrongylides (Dioctophymatidae) have a complex life cycle, which includes oligochaetes and fish as intermediate hosts, and piscivorous birds as definitive hosts. In fish, fourth stage larvae can be found in the body cavity, under serous membranes, and in the musculature. The parasite has a zoonotic potential and humans can get infected by consumption of raw or undercooked fish. Recently, there have been several reports on the occurrence of Eustrongylides excisus larvae in perch in Europe. There are
no data on the presence of Eustrongylides larvae in fish in Croatia. Examination of perch collected from the Kupa River, Jarun Lake and Lonjsko polje revealed the presence of Eustrongylides sp. larvae. In this work, a detailed morphological and morphometric description of fourth stage larvae from perch is given. These data contribute to the current knowledge about the distribution of Eustrongylides larvae in Europe.
