BACKGROUND In Anzali Lagoon, there are some endemic and exotic fishes. The present study was conducted to compare the parasitic fauna of Blicca bjeorkna, as an endemic fish and Hemiculter leucisculus, as an introduced fish to the lagoon. METHODS A parasitological investigation was done on 78 specimens of B. bjoerkna and 114 of H. leucisculus. The fishes were collected from August 2009 to Apri...

Paradiplozoon hemiculteri (Ling, 1973), a member of the Diplozoidae, parasitizes the gills of Asian fish. Not only is the type material unavailable for this species, the original description was poor and somewhat conflicting, and adequate molecular data were not available. What is more, the available morphological and molecular data are inconsistent and fluctuate significantly. Here, we present...
جهت بررسی ترکیب گونه ای ماهیان تالابهای بین المللی استان گلستان که یک سری از دریاچه های تقریبا ایزوله آب شیرین میباشند، از شهریور 1379 تا مرداد 1381مطالعه انجام شد. نتایج نشان داد که گونه های غیر بومی در تالابها غالب میباشند. از 10 گونه نمونه برداری شده ، چهار گونه شامل تیزه کولی(hemiculter leucisculus) ، کاراس (carassius auratus)، آمورچه(pseudorasbora parva) و گامبوزیا (gambusia)غیر بومی بودند...
گونه تیزه کولی (Hemiculter leucisculus) از خانواده کپور ماهیان (Cyprinidae) و غیربومی ایران بوده و اطلاعات بسیار محدودی در مورد زیستشناسی آن وجود دارد. مجموع 91 قطعه ماهی تیزه کولی (H. leucisculus) در رودخانه گرگانرود از فروردین تا تیر ماه 91 توسط دستگاه الکتروشوکر بصورت تصادفی صید و سپس با فرمالین 10 درصد تثبیت گردید. نسبت جنسی نر به ماده در جمعیت مورد مطالعه 53/1 : 1 و نرها غالب بودند. بیشین...
این تحقیق جهت تعیین زیستشناسی تولید مثل ماهی تیزه کولی Hemiculter leucisculus در رودخانه گرگانرود انجام گردید. مجموع 36 قطعه ماهی تیزه کولی (Hemiculter leucisculus) در رودخانه گرگانرود از فروردین ماه تا تیر ماه 91 توسط دستگاه الکتروشوکر بصورت تصادفی صید و سپس با فرمالین 10 درصد تثبیت شد. بیشینه شاخص گنادوسوماتیک برای هر دو جنس در تیر ماه مشاهده شد، که مقدار آن برای نرها و مادهها به ترتیب 56/2...
this paper provides information on the geographic distributions of two cyprinid species: hemiculter leucisculus (basilewsky, 1855) and alburnus caeruleus heckel, 1843, in the world and the entire drainage systems in iran. the new distribution records were taken from maroon river (jarrahi river system) and chardaval river (karkheh river system), both in tigris river basin showing wide and narrow...
Cyprinid fish, Hemiculter leucisculus, Cultrichthys erythropterus and Culter dabryi, were sampled from Liangzi, Honghu and Tangxun lakes in the flood plain of the Yangtze River. The cestode Bothriocephalus acheilognathi Yamaguti, 1934 was found in the 3 lakes, but C. erythropterus sampled from Liangzi lake was found uninfected due probably to the small sample size. Findings of the cestode in th...

A survey was performed to investigate the infection status of fishborne trematode (FBT) metacercariae in freshwater fish from Guangxi Zhuang Autonomous Region, China. A total of 307 freshwater fish of 31 species were collected from 5 administrative regions of Guangxi Zhuang Autonomous Region. They were examined by artificial digestion method from July 2003 to August 2004. No metacercariae were ...
