In this study, the chronic toxic effects of Pb (II) on common carp, Cyprius carpio were  investigated using  several  biomarkers at different levels of biological functions for assessing changes in ecosystem quality. In a bioassay, common carp juveniles were individually exposed to different dose of heavy metal, Pb II (0, 0.45, 0.89, 1.34 mg.l-1) for 28 days. Morphological indices such as hepat...

DNA fragments related to the cloudy catshark Scyliorhinus torazame L-gulono-gamma-lactone oxidase (GULO) cDNA were detected in a distant fish species. Although the Southern hybridization pattern was more distinct in species with active GULO, DNA fragments related to the GULO gene were also discovered in the common carp Cyprinus carpio. Additionally, in the common carp, inter-individual variatio...

There are a variety of approaches to identify groups of genes that change in expression in response to a particular stimulus or environment. We here describe the application of suppression subtractive hybridization (SSH) for isolation and identification genes in the brain of common carp (Cyprinus carpio) under cold temperatures. The materials were prepared through cooling the hybrid F2 of purse...

L-Lactate and pyruvate permeability and utilization in carp (Cyprinus carpio) red blood cells was studied in vitro with tracer methods. Transport of lactate and pyruvate across the carp red blood cell membrane is rapid. At low plasma concentrations, lactate and pyruvate are transported into carp red blood cells mainly via a specific monocarboxylate carrier. This is shown by a study of the satur...

Sci., Supplement 1: 62–71 The paper presents a comparative analysis of proximate and fatty acid composition of seven fi sh species from the Danube River including asp (Aspius aspius), common bream (Abramis brama), common barbe...

The effects of various salinity levels among (0‰, 5‰, 10‰, 15‰, and 20‰) for successful breeding of Common carp, Cyprinus carpio were investigated. The duration of study was 75 days. Ripe broodstock (30) having a mean weight (male 1027±2.4g and female 1084.8±23g) were selected and stocked into spawning tanks (2000-liter). The Ratio among male and female was 2:1. They were fed with commercial fl...

A species not identifiable with any of the about 23 Myxobolus species recorded from the common carp so far, was detected in the gills of one- and two-summer-old specimens of the common carp ((Cyprinus carpio L.) cultured in pond farms in Hungary. The strictly tissue-specific plasmodia of the parasite were located, surrounded by hyaline cartilage cells, in the chondrous substance of the terminal...
