چکیده
ماهی کولیکورا، Alburnus filippii،از خانوادۀ کپورماهیان است و از رودخانه های ارس و سفیدرود و تالاب انزلی دیده شده است. با توجه فقدان اطلاعات کافی در باب ویژگیهای استخوان شناسی، گونۀ A. filippii این تحقیق با هدف توصیف ساختار اسکلتی آن به اجرا درآمد. برای این پژوهش تعداد 20 قطعه ماهی به وسیلۀ دستگاه الکتروشوکر از رودخانۀ اهرچای صید و پس از تثبیت در فرمالین 10 درصد بافری، برای انجام مطالعات استخوان شناسی رنگ آمیزی و شفاف سازی شدند. سپس، ویژگیهای استخوانی گونۀ A. filippii به تفصیل توصیف و با ساختارهای اسکلتی توصیف شدۀ دیگر گونه های جنس Alburnus مقایسه شد. براساس نتایج، گونۀ A. filippii یافتهها نشان داد مجموعه ای از ویژگیهای استخوانی شامل تیزبودن زائدۀ میانی استخوان فکی، وجود تمایل به بالا در زائدۀ کورونوئید، برآمده بودن حاشیۀ قدامی استخوان فکی لامی، بادبزنی شکل بودن بخش قدامی استخوان قاعده ای لامی، تیزبودن بخش خلفی استخوان پیشومر، کوچک بودن چهارمین قطعه استخوان زیرچشمی و وجود تعداد 11 استخوان پتریگیوفور در ساختار بالۀ پشتی از دیگر گونه های این جنس در ایران تشخیص پذیر است.

چکیده English

Kura bleak, Alburnus filippii, a member of the family Cyprinidae, is found in the rivers of Aras and Sefidrud, and the Anzali lagoon of Iran. The current study was conducted to provide a detailed osteological description of this sp-ecies since there was not adequate information in this regard. In order to attain this goal, 20 specimens were collected from the Ahar Chay River by electrofishing device, and fixed in 10% buffered formalin. The specimens were cleared, stained with alizarin red S and alcian blue for osteological examination and a detailed description of its skeletal structure was provided. The results showed that this species can be distinguished from other members of this genus in Iran by a combination of osteological characters, including having pointed process of the maxillae, dorsal tilting of the coronoid process, protruding of the anterior margin of the hyomandibular, fan-shaped anterior part of the basihyal, pointed end of the pre-vomer posteriorly, small fourth infraorbital and 11 pterygiophors in the dorsal fin.
