1. Crucian carp (Carassius carassius L.) and Common carp (Cyprinus carpio L.) were subjected to 2h progressive hypoxia followed by up to 6 h anoxia in closed respirometers at 15 °C. 2. The concentrations of glycogen, glucose, phosphoryl creatine, alanine, succinate, lactate, ethanol and ammonia were determined in whole Crucian carp following exposure to both hypoxia and anoxia. 3. Ethanol and l...

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...

The present study was designed to investigate acute toxicity of dimethoate on juvenile Cyprinus carpio var. communis. Fishes weighing 10 ± 2 gms were selected and mortality data was statistically evaluated by Finney's Probit Method. The 96-hour LC50 value for Cyprinus carpio was found as 1.1 ppm in static bioassay system. Mean values of physicochemical parameters of aquarium waters determined d...

the hazardous effect of heavy metals on the histopathology of selected organs of the freshwater fish common carp (cyprinus carpio l.) was investigated. gill, liver, kidney and flesh samples were collected after 32 days of exposure to a sublethal concentration of 5 mg/l of combined (cd + pb + cr + ni) metal solution containing 1.25 mg/l of each metal ion (1/10th of lc50 / 48h) was analyzed by us...

Prothymosin alpha (ProTα) and thymosin beta (Tβ), members of the thymosin family, consist of a series of highly conserved peptides capable of stimulating immune responses in different species. Our recently published report discussed an issue of the conserved roles of ProTα b and Tβ-like (Tβ-l) in common carp (Cyprinus carpio L), which suggested that the highly-conserved carp ProTα b and Tβ-l ca...

qualitative and quantitative analyses of phyto- and zooplankton, and growth performance of cyprinus carpio linnaeus were done in earthen vats receiving compost, diammonium phosphate and vermicompost as direct application fertilizer were conducted. significant differences were observed in the diversity and abundance of plankton in response to fertilization. the highest production of fish was obt...
