Juvenile common carp Cyprinus carpio were collected from 10 lakes with variable predator abundance over 4 months to evaluate if morphological defences increased with increasing predation risk. Cyprinus carpio dorsal and pectoral spines were longer and body depth was deeper when predators were more abundant, with differences becoming more pronounced from July to October. To determine if morpholo...

Concentrations of Ag, Cu and Zn were studied in muscle and liver of Barbus plebejus, Cyprinus carpio and Leuciscus cephalus from Kilickaya Reservoir. The heavy metal analysis of samples were carried out by using a flame atomic absorption spectrophotometer. The mean heavy metal concentrations of Ag, Cu and Zn were obtained as 1.47±3.44, 1.65±3.31 and 2.89±4.52 μg/g in muscle and 1.78±4.19, 2.07±...

Isolation of Aeromonas hydrophila and Evaluation Its Pathological Effects on Koi Fish (Cyprinus carpio)

OBJECTIVE The aim of this study was identification of the parasites of the common carp from Tahtalı Dam Lake. METHODS The fish were transported live to the laboratory. They were investigated for ectoparasites and endoparasites. The parasite specimens were fixed and identified. RESULTS During the study, 47 common carp were caught monthly and 3 species of metazoan parasites were found: Dactyl...

Comparison of protein, fat, ash and dry matter content common carp, Cyprinus carpio L. silver Hypophthalmichthys molitrix fillet

We examined and compared heavy metals bioaccumulation in Cyprinus carpio and Labeo rohita netted from Sardaryab, a tributary of River Kabul. By using atomic absorption spectrometry we assessed different organs including livers, gills, and muscles. Metals studied were chromium, iron, zinc, lead, and copper. Livers of both species showed higher concentrations of metals while muscles showed the le...
