Abstract
The study is an endoparasitic examination of chub mackerel (Scomber japonicus Houttuyn 1782), bogue (Boops boops Linnaeus 1758), horse mackerel (Trachurus trachurus Linnaeus 1758), sardine (Sardina pilchardus Walbaum 1792), and anchovy (Engraulis encrasicolus Linnaeus 1758) fish taken from Çanakkale fish state as an annual sampling between 01 September 2019- 01 September 2020. One thousand three hundred thirty-seven fishes were sampled. The external morphological examination of the fish brought to the laboratory was made, then the conditions of their visceral organs and their visceral structures were examined by dissection method. Nematodes collected alive from many parts of the body were kept in absolute (99.9%) ethanol. Parasites in ethanol were kept in glycerin for a few days before being examined under the microscope. Nematodes were first examined morphologically on a stereomicroscope and then under a light microscope for easy species identification. Classical detection methods have been used for species determination. As a result, among the individuals belonging to the Anisakidae family, Anisakis spp. L3 larval stage type 1 and type 2, Anisakis physeteris larval stage, Contracaecum larval stage, Hysterothylacium aduncum L3 larval stage were found. The density, abundance, and prevalence rates of the parasites in the infected fish are determined as a percentage.
