This study presents a detailed record of the philometrid nematodt, Philometm lateolabmcis (Nematoda: Philometridae) and trypanorhynch pleurocercoid, Grillotia sp. (Cestoda: Trypanorhynchia) in white grouper, Epinephelus aeneus, and dusky grouper, E. marginatus, from iskenderun Bay, Turkey, during 2000-2003. A total of 885 (418 white and 467 dusky grouper) serranids were sampled during the research period. Of these fish, 130 (31.1%) white and 118 (25.3%) dusky groupers were found infected with helminthes. In order to estimate the influences of helminthic infestation on fish growth, the length-weight relationship was determined. Trypanorhynch cestodes larvae were collected only from the external mesenteries of the internal organs, whereas philometrid nematodes were found in the ovary of the infected fish. Severe pathologic changes were detected in the ovary tissues of white groupers infected with P. lateolabracis.
