Abstract Aspirin is one of the most widely used medications globally as an analgesic and antipyretic drug. use antiparasitic against fish parasites has never been tested. The parasite Dactylogyrus considered a serious threat to freshwater aquaculture in relation considerable losses. present study aimed evaluate effect aspirin extensus on Cyprinus carpio alteration gill histopathology. In vitro ...

Infections of common carp Cyprinus carpio and koi, its coloured morphotypes, with the cyprinid herpesvirus 3 (CyHV-3) can induce severe clinical signs and increased mortality in affected stocks. This may significantly challenge the economic basis of carp farming in Central Europe. To limit virus spread in carp farms, effective disinfection measures for ponds stocked with infected populations ar...

The present study was conducted to determine the bacterial contamination and prevalence of foodborne pathogens in imported frozen fish. A total of 450 imported fish samples [65 catfish (Pangasius pangasius), 45 mirgal (Cirrhinus mrigala), 135 tilapia (Oreochromis niloticus), 50 carfoo (Cyprinus carpio), 75 Rohu (Labeo rohita), 35 milk fish (Chanos chanos) and 45 Mackerel (Rastrelliger brachysom...

Using the common carp Cyprinus carpio L. in polyculture ponds to increase both phytoand zooplankton availability has become a popular practice for the cultivation of plankti vorous fish, such as rohu Labeo rohita Hamilton. However, the dynamics of how common carp influences the environment and ecology in polyculture ponds are unclear. In the present study, the effects of various stocking densit...

This study details the nutritional and digestive properties of protein isolates that are extracted from carp (Cyprinus Carpio L.) muscle using pH shifting methods. Alkaline (ALPI) and acid (ACPI) protein isolates exhibit higher protein yields (87.6%, 76.3%, respectively). In addition to the high recovery of myofibrillar protein, a portion of the water-soluble proteins is also recovered. The moi...

A 12 day growth trial was conducted to compare the effect of the variation in microcystins (MC) composition of two bloom samples of Microcystis aeruginosa on the growth performance and microcystin accumulation in common carp Cyprinus carpio larvae. Two M. aeruginosa natural bloom samples with different MC profiles were collected and larvae were exposed to cyanobacterial cells through their diet...

Five highly variable microsatellite loci were used to investigate genetic variations and population structure of common carp of Caspian Sea. A total of 54 fish were genotyped giving 35 alleles over all loci. The mean number of alleles, per locus in population ranges from 5.5 to 13.0 and the mean observed heterozygosity at the five loci was 0.84. An analysis of genetic variations indicated the H...

Four important hungarian common carp (Cyprinus carpio l.) breeds (attala mirror, attala scaled, hortobágy scaled and Szeged mirror) harvested from different fish farms were analysed in this study. Main body indices, slaughter characteristics, fillet fat content, and conventional fish flesh quality characteristics were measured and compared. the slaughter value of the mirror strains tended to ex...

cDNA clones encoding the myosin regulatory light chain (RLC) were isolated from a cDNA library prepared from fast skeletal muscle of the carp Cyprinus carpio L. Two types of cDNA clone encoding carp RLC were found with identical deduced amino acid sequences. The two mRNAs differed in the number of polyadenylation signals prior to the poly(A) tail in the 3' non-coding region. The two mRNA specie...

The myofibrillar ATPase activity of the epaxial white muscle was measured in carp Cyprinus carpio L. acclimated to 10 degrees C or 28 degrees C. As previously reported, cold acclimation was associated with an increase in the ATPase specific activity and a decrease in the thermostability. The water content of the white muscle was significantly higher in cold-acclimated fish than in warm-acclimat...
