ABSTRACT PhD THESIS
The Endoparasites and Histopathologies Found in the Some Commercial Teleosts in the Bay of iskenderun

In this study, the some commercially important teleosts collected from the Bay of iskenderun were examined in terms of presence and pathologies of endoparasites. 1790 specimens (805 individuals of Family Sparidae; 595 ind. of Family Serranidae; 390 ind. of the others) including total 19 species belonging to 8 different families were collected as a sample of this study. The existence of invasion of endoparasites (11.84%) was identified in 212 specimens. The Nematode Hysterothylacium sp. (Ascaridoidea: Anisakidae) was found in intestine of Sparidae species (Spams aurata, Diplodus cervinus, Diplodus vulgaris, Diplodus sargus, Pagellus erythrinus, Pagrus auriga, Pagrus coeruleostictus, Dentex dentex). Additionally, the larval form (stage) of trypanorhynch cestod (Cestoda: Eucestoda: Trypanorhynchidea) in body cavities (on the internal organs and mesenteric tissues) and Philometra sp. (Nematoda: Dracunculoidea: Philometridae) in the ovaries of four species (Epinephelus aeneus, E. marginatus, E. costae ve Mycteroperca rubra) of Serranidae were determined. However, it was observed that there was no endoparasites in other samples [Sciaena umbra, Umbrina cirrosa (Sciaenidae), Mullus barbatus (Mullidae), Soka solea (Soleidae), Spicara flexuosa (Cenracanthidae), Merluccius merluccius (Merlucciidae), Pelates quadrilineatus (Teraponidae)]. Regarding histopathological findings of those endoparasites, it was found that philometrid nematode in those fish ovaries caused severe degeneration. There is no significant histopathological destruction was determined for the vital organs or systems of the other parasitised teleosts specimens.
