– the normal and lateral line cycloid scales of a cyprinid fish capoeta damascina (valenciennes incuvier and valenciennes, 1842) have been subjected to the scanning electron microscopy technique in orderto study their detailed structure. the scales have the general morphological characteristics of the cycloidscales. in the normal scale located below the dorsal fin, the focus lies towards the an...
as a part of a major ecological study of hanna wetland, semirum region, isfahan province, parasitic infestation of 3 native and one introduced fish species were investigated. a total of 120 fish specimens were collected by both cast net and a series of gillnets between fall and winter 2007, and spring and summer 2008. some of the observed parasites are reported for the first time as new host re...
In a parasitic survey of the native and introduced fishes in the Zayandehrud River, 5 Myxobolus spp. were found in the gills, fins and skin of examined fish specimens. They include M. varicorhini from fin and M. samgoricus from skin of Capoeta damascina, M. musajevi from gills of Capoeta capoeta gracilis, Myxobolus cristatus from Capoeta aculeata, and M. saidovi from Alburnus sp. Data on the lo...
In the present study, we investigated the effects of a sub-acute concentration of cypermethrin on some hematological parameters of Capoeta damascina. The specimens had an average weight of 150 ± 10 g and average length of 21 ± 1 cm (mean ± SD). The fish were exposed to 0, 0.25, 0.5, and 0.75 µg/L (each with 3 replicates) for 10 days. Blood samples were collected on days 1, 5 and 9. Hemoglobin (...
This study was conducted to determine ichthyofauna of the Büyük Karaçay stream of the River Orontes drainage in Turkey (eastern Mediterranaen basin). As the result of examination of the 911 individuals collected between June 2012 and May 2013, eight fish species belonging to five families have been recorded. Of these, African catfish Clarias gariepinus (Burchell, 1822), yellow barbel Carasobarb...
In this paper, the metazoan parasite community system of Capoeta damascina in the Tigris basin (Mesopotamian region) in the Middle-East is presented. Overall, 54 species have been identified. Between 2005 and 2008, Iranian surveys of Capoeta damascina found a total of 47 metazoan parasites species, most identified to species level. In addition, 6 parasite species from Iraq and 1 species from oc...
the present study investigated the effects of acute toxicity of malathion on behavioral and haematological parameters in the cyprinid capoeta damascina . the specimens were collected from the kordan river, karaj, iran in august, 2014 and were exposed to different concentrations of malathion at the laboratory (24, 48, 72 mg l ‑1 ) based on 96h-lc (10; 30; 50; 90) which was 6.08 (5.22-7.18) mg l ...
زیستگاه به عنوان یکی از مهمترین عوامل در حفاظت از گونهها مطرح میباشد. زیرا با تعیین خصوصیات زیستگاهی موردپسند بهوسیلهی گونههای در معرض خطر، میتوان طرحهای حفاظتی ارائه کرد. براین اساس، مطالعهی حاضر بهمنظور بررسی نیازهای زیستگاهی سیاهماهی توئینی در رودخانه کردان انجام شده است. نمونهبرداری از سه ایستگاه اصلی در دو فصل تابستان و زمستان صورت گرفت. در طول رودخانه سه ایستگاه نمونهبرداری...
دیازینون یکی از پرکاربردترین آفت کش های گروه ارگانوفسفره است که پس از استفاده به منظور ازبین بردن آفات مختلف ممکن است به محیط های آبی راه یابد و تأثیراتی را در آبزیان و در نهایت انسان بگذارد. به همین علت، مطالعة حاضر به منظور بررسی تأثیرات غلظت های 5/0، 1 و 5/1 پی پی ام (که قبلاً در برخی مناطق تخمین زده شده بودند) از آفت کش دیازینون در پارامترهای هماتولوژیک (هموگلوبین، هماتوکریت، گلبول های قرمز،...
