| Abstract | ||
| Introduction: The greasy grouper (Epinephelus coioides) is a species of fish belonging to the family Serranidae and is a valuable fish in the Persian Gulf . Parasitic infections may affect the morphometric characteristics of fish. This study investigated the morphometric characteristics of the greasy grouper in the coastal of Bandar Abbas, its infection with helminths, and the morphometric characteristics differences between infected and non-infected fish. Methods: A total of 50 greasy grouper specimens were collected from the coastal of Bandar Abbas and transferred to the laboratory. Fifteen morphometric characteristics, including total weight, total length, standard length, dorsal fin length, ventral fin length, caudal fin length, anal anal fin length, pectoral fin length, interorbital distance, dorsal fin base, pelvic fin base, caudal fin base, anal fin base, pectoral fin base, and snout to eye distance, were measured using a digital caliper with an accuracy of 1 mm and a digital scale with an accuracy of 1 gram. Results: The identified parasites were the trematode Opercoelus acutus with an 8% prevalence, the trematode Erilepturus hamati with a 2% prevalence, and the cestode Scolex pleuronectis with a 2% prevalence. Except for two cases (head length and snout to dorsal fin distance), no significant differences were observed between infected and non-infected fish. Conclusion: The greasy grouper exhibited a low overall prevalence of helminth parasites, primarily dominated by the trematode Opercoelus acutus. The parasitological infection showed minimal significant impact on the overall morphometric characteristics of the host fish. The lack of significant differences in the vast majority of the measured morphometric parameters between infested and non-infested individuals suggests that the observed parasitic load, at these prevalence and presumably intensity levels, does not substantially affect the external body structure or growth patterns of the greasy grouper in this habitat. | ||
