The present study was conducted on two species of cyprinid fish: Common Carp (Cyprinus carpio) and grass (Ctenopharyngodon idella). includes the effect increasing salinity survival rate, oxygen consumption, glucose total protein levels in blood plasma, energy usage, food consumption growth rate. carp show more resistance to with 90% rate 15 g/l salinity. While did not survive than 5 g/L. Increa...

White muscle strains were recorded using sonomicrometry techniques for 70 fast-starts in the common carp Cyprinus carpio L. High-speed cine images were recorded simultaneously for 54 of these starts, and muscle strain was calculated independently from the digitized outlines of the fish. Sonomicrometry measurements of superficial muscle strain were not significantly different from the strain as ...

In this study, the effect of ethanolic Aloe vera extract as a natural antibiotic on growth performance of common carp (Cyprinus carpio) was studied. Fish with an average weight of 29.74±1.20 g and the mean length of 11.50±0.28 cm were divided randomly into 4 treatments (a control and other groups treated with the extract of 0.1, 0.5 and 2.5% in the diet with 3 replicates and density of 10 fish ...

The Asian fish tapeworm, Bothriocephalus acheilognathi, has been considered one of the most dangerous parasites for cultured carp and a risk for native freshwater fish populations worldwide. This cestode is highly pathogenic for fishes especially fry. In this paper we record B. acheilognathi parasitizing the endangered and endemic freshwater fish Profundulus hildebrandi from the endorheic basin...

Common carp (Cyprinus carpio) is a widespread freshwater fish species of the Cyprinidae family, one largest and most diverse families. The natural habitats C. carpio extend from Western Europe to South-East Asia. has remained an economically important in aquaculture for many centuries its production nowadays exceeds 4 million tons worldwide continues grow. taxonomy complicated, since this usual...

The present study aimed to determine the zinc accumulation levels in gill, liver, and muscle tissues of Cyprinus carpio (Linnaeus, 1758) under effect (2.0 4.0 ppm) + EDTA 8.0 for 7, 15, 30 days effects on tissues. Tissue were determined by inductively coupled plasma-mass spectrometry (ICP˗MS). No mortality occurred fish exposure times concentrations with solutions containing only combined EDTA....

Thin-section studies of the sino-auricular border region in the hearts of 20 species of teleost fish revealed the cardiac internuncial cell (CIC), hitherto known only in Misgurnus, to occur also in 8 species (Acheilognathus lanceolatus, Carassius auratus longsdorffii, Cyprinus carpio, Girella punctata, Kareius bicoloratus, Rhodeus ocellatus ocellatus, Rhyncopelates oxyrhynchus, Tilapia nilotica...

heterophyidosis is a fish-transmitted disease in khuzestan province, therefore a total of 900 fresh water fishes belonging to cyprinus carpio, liza abtt and gambosia affinis, were collected from canals of mazreeh district in the central area of khuzestan. in 44%, metaccrcariae of three small flukes of human including haplorchis taickut, haplorchis pumilio, stellanichasmus falcamtus were found. ...

Koi herpesvirus (KHV) is a pathogen agent that predominantly affects common and koi carp (Cyprinus carpio and Cyprinus carpio koi, respectively) causing disease and mass mortality in farmed and wild populations of these breeds. Following the first reports of KHV in Israel and Germany in 1998, the geographical range of this disease has become extensive. The disease has been spread to many countr...

Carassius carassius responds to hypoxic conditions by conversion of lactate into ethanol, which is excreted over the gills. However, a closely related species, Cyprinus carpio, does not possess the ability to produce ethanol and would be expected to accumulate lactate during hypoxic exposure. While the increase in oxygen consumption in fish required following strenuous exercise or low environme...
