in this study, a total of 146 specimen of fish species from garmrood river of amol, mazandaran province in the summer 2011 were caught by local fishermen which including ,10 sand goby (neogobius fluviatilis),4 round goby (neogobius melanostomus), 48 capoeta capoeta, 73 albernoides bipunctatus, 5 leuciscus cephalus, 7 cobitis taenia and 4 nemacheilus nemacheilus. the fishes were transported a li...

In many aquatic environments elevated levels of trace elements occur due to anthropogenic activities. Water organisms can be precise indicators in estimating the status of pollution of water environments. Among them several species of fish have been widely used (Håkanson 1984, Chevreuil et al. 1995, Andres et al. 2000, Falandysz et al. 2000, Perkowska and Protasowicki 2000, Řehulka 2001, Wagner...

Concentrations of heavy metals (Cd, Cr, Cu, Pb and Zn) were measured in water, bottom sediment and tissues (muscle and gills) of Leuciscus cephalus from the Dipsiz stream in the Yatagan basin (southwestern Turkey), the site of a thermal power plant. Results for levels in water were compared with national and international water quality guidelines, as well as literature values were reported for ...

Myxobolus gayerae sp. n. and M. leuciscini González-Lanza & Alvarez-Pellitero, 1985 (Myxozoa: Myxobolidae) have been described and re-described from European chub Leuciscus cephalus L. from the Hungarian stretch of the river Danube. The ellipsoidal plasmodia of M. gayerae sp. n. were found in the mucosa of the intestinal wall, whereas the large, elongated plasmodia of M. leuciscini infected the...

To test the hypothesis that different species have similar responses to local and regional environmental constraints, we modelled the occurrences of 13 species using a data set of 413 undisturbed river reaches. Three environmental descriptors were considered at the local scale (river slope, river width, and upstream drainage area) and three at the regional scale (mean annual and mean range air ...

this paper presents a total of 11 known crustacean parasite species from 51 host species belonging to 7 families, with 17 genera reported from cultured and wild fishes in three faunal regions of iran. among them, one belonging to branchiura order, namely argulus foliaceus, was found on capoeta capoeta in makoo reservoir as well as on cyprinus carpio, chalcalburnus sp., hypophthalmichthys molitr...

Abstract The aim of this study was to compare the susceptibility body deformities in juveniles 13 common European cypriniform fish, caused by intensive feeding with same commercial dry diet administered at 25°C according a similar schedule. final share individuals malformations differed considerably among species and 0.0-87.0%. Unaffected were only Barbus barbus (L.), Chondrostoma nasus Cyprinu...
