Various parasite species were found in Carassius carassius including Diplostomum spathaceum, Dactylogyrus sp.,Gyrodactylus sp. Ichthyophthirius multifiliis and Trichodinia sp . They were found in four rivers in West Azerbaijan Province (North-Western Iran) . A total of 207 live Carassius carassius from four rivers including Aras (72) Zariyneh (42) Nazlo (58) and Barandoz (35) were studied. Pa...

Trypanosoma danilewskyi Laveran & Mesnil, 1904 caused anorexia in experimentally infected goldfish Carassius auratus. This was most evident when the parasiternias were high. Some anorexic fish died of high parasitemias but those that s u ~ v e d the crisis returned to normal feeding.

polybrominated diphenyl ethers (pbdes) have been widely used in many products as flameretardants, which resulted in their release into the environment. little is known about the impact of coexisting pbdes on organisms. in this study, the in vivo effects of bde-47 and bde-99 on a suite of biomarkers, acetyl cholinesterase (ache), ethoxyresorufin-o-deethylase (erod), glutathione-s-transferase (gs...

A new member of the inward-rectifier K(+) channel subfamily Kir2 was isolated and characterised from the crucian carp (Carassius carassius) heart. When expressed in COS-1 cells this 422 amino acid protein produced an inward-rectifying channel with distinct single-channel conductance, mean open time and open probability. Phylogenetic sequence comparisons indicate that it is not homologous to any...

How fish communities change with eutrophication in temperate lakes is well documented, while only a few studies are available from subtropical lakes. We investigate the community structure 36 located Yangtze River basin, covering wide nutrient gradient. found that species richness and total catch per unit effort (CPUE) increased significantly chlorophyll (Chla). Among different feeding types, p...
