چکیده

خلیج‌فارس از نظر اقتصادی، محیط زیستی و سیاسی دارای اهمیت فراوانی بوده و زیستگاه حدود 205 گونه ماهی است که تنها تعداد معدودی از آن‌ها از نظر انگل‌شناسی مورد مطالعه قرار گرفته‌اند. مطالعه حاضر به منظور بررسی آلودگی‌های کرمی درکفشک ماهی زبان گاوی (Cynoglossus bilineatus) حوزه خلیج‌فارس (شهر اهواز) صورت گرفت. در تحقیق حاضر در طی بهار سال 1395، تعداد 100 قطعه کفشک ماهی زبان گاوی خریداری و به آزمایشگاه منتقل گردید. انگل‌های جدا شده از قسمت‌های مختلف ماهی در الکل 70 درصد تثبیت گردیدند و سپس توسط کلید تشخیصی، شناسایی گردیدند. در این بررسی، 82 درصد از ماهی‌های نمونه‌برداری ‌شده آلودگی انگلی داشتند. بیشترین میزان آلودگی مربوط به دو نوع ترماتود ترپتودموئیدس فوکه‌ننسیس و آفانوروئیدس لترینی بودند که گونه اول فراوانی بیشتری را نشان داد. بررسی‌ها نشان داد که دو گونه ترماتود شناسایی شده تاکنون از این ماهی گزارش نگردیده‌اند. سایر نماتودها شامل کاپیلاریا، پروسکوم و رافیدآسکاروئیدس نیپوننسیس نیز در دستگاه گوارش، کبد و حفره شکمی این ماهی وجود داشت. نتایج هم‌بستگی پیرسون نشان داد که بین تعداد هر کدام از ترماتودهای شناسایی شده که بیشترین آلودگی را در این ماهی داشتند با وزن و طول ماهی هیچ گونه رابطه معنی‌داری وجود ندارد.

چکیده [English]

Persian Gulf is very important economically, environmentally and politically that habitat of nearly 250 species of fish that a few of them have been studied parasitically. This study accomplished to investigate the worms of Cynoglossus bilineatus in district of Persian Gulf (Ahvaz). In this study during March to June 2016, 100 pieces of Cynoglossus bilineatus bought and transferred to laboratory. Separated parasites from different parts of fish stabilized in 70% alcohol and then identified with identification keys. In this survey, 82% of sampled fish had helminthic infestations. The most value of infestation regarding to two kinds of trematodes Treptodemoides fukenensis and Aphanuroides lethrini that the first species showed greater frequency. Reviews showed that two identified trematodes have not been reported before form this fish. There were also other nematodes including Capillaria, Procaecum and Raphidascaroides nipponensis in gastrointestinal tract, liver and abdominal cavity. The results of paersons correlation showed that there weren’t any significant correlation between the number of each identified trematodes and the weight and length of this fish.
