BACKGROUND Knowledge about Alburnoides remains lacking relative to many other species, resulting in a lack of a systematic position and taxonomic diagnosis. Basic biological information for Alburnoides has been constructed, and it is necessary to understand further and obtain more information about this species. Its phylogenetic relationships are still debated and no molecular data have been us...

Bu çalışmada; 2017 ve 2019 tarihleri arasında Pülümür Nehri'nden yakalanan noktalı inci balığı Alburnoides bipunctatus (Bloch, 1782)’un boy-ağırlık ilişkisi kondisyon faktörü araştırılmıştır. Örneklerin total boy uzunlukları ağırlıkları dişilerde 7,1-11,6 cm 2,9-12,3 g; erkeklerde 7,0-11,9 2,7-13,5 g değişmiştir. Dişi/erkek oranı 1/0,87 olarak hesaplanmıştır. Boy-ağırlık ilişkileri W=0,0111TL2,...

OBJECTIVE This study was conducted to determine the prevalence of Ligula intestinalis and infections caused by these on freshwater fish in rivers and streams in the Kars plateau of north-eastern Anatolia, Turkey. METHODS This research was conducted between April and July 2011. Fish samples were caught via a casting net and an electro-shocker. The samples were immediately examined to determine...
This paper considers the length–weight relationship of six out of eight most commonly found fish species inhabiting the Vardar River biotope, the largest riverine system in the central part of the Balkan Peninsula: Alburnoides bipunctatus (Bloch, 1782); Alburnus alburnus (Linnaeus, 1758), Barbus macedonicus Karaman, 1928; Barbus peloponnesius Valenciennes, 1842; Chondrostoma vardarense Karaman,...
در این مطالعه، برخی پارامترهای پویایی جمعیت ماهی خیاطه alburnoides bipunctatus و رابطه آن با عوامل محیطی در نهرهای کبودوال، تیل آباد و شیر آباد استان گلستان در سال 89-1388 بررسی گردید. نمونه های ماهی با استفاده از دستگاه الکتروشوکر (با قدرت 7/1 کیلووات و جریان مستقیم 300-200 ولت) صید شدند. در مقایسه ریخت شناسی ماهیان هر سه نهر، صفات ارتفاع باله مخرجی، ارتفاع باله شکمی، طول قاعده باله سینه ای، ا...
