Carp is one of the most widely cultivated warm water fish, which has been introduced into many countries. It is essential for the manager of a carp farm to know the production costs and their evolution, showing the main inputs on which the cost reduction is worth effort. In Iran, carp farming is mainly based on common carp, silver carp, grass carp, and bighead carp, which were often reared in p...

Although carp is still widely sold and used in its fresh form, a range of value additions may also be observed. It is essential to know the development and management of a carp farm production costs and their evolution. In Iran, warm-water fish farming is based on common, silver, grass, and bighead carps. The carp is easy to rise in hatcheries in very large numbers at little cost, and is distri...

Date palm seed (Phoenix dactylifera) (DPS) extract has been used worldwide in pharmaceutical agent due to its constituents. This study aimed to assess the effects of DPS extract as a dietary supplementation at on the body composition, lipid peroxidation and tissue quality of common carp (Cyprinus carpio) based on the total volatile nitrogen (TVN) test. Common carp juveniles weighing ca 32 g wer...

To improve the performance of growth traits and survival in common carp, CyCa nucleocytoplasmic hybrid fish (C) was used as parental fish for hybridization with Russian scattered mirror carp (R). Performances in morphological characters, growth traits and survival rate were compared among the purebreds (CC &RR) and crossbreds (RC &CR) at different time period in solitary and communal rearing sy...

Injured fish skin leaks alarm substances that induce the fright reaction upon olfactory detection. The skin also contains a multitude of other odorants traditionally related to other behaviors, but to what extent they are detected upon injury is unknown. We have performed single unit recordings in the olfactory bulb (OB) of crucian carp while exposing the olfactory epithelium to skin extracts f...

OBJECTIVES An interrelationship between rheumatoid arthritis (RA) and periodontitis has been suggested due to their common pathogenic mechanisms. Protein carbamylation and neutrophil extracellular traps (NETs) formation have been shown to be related to autoimmune conditions, including RA, but their association with periodontitis has not been elucidated. Therefore, we assessed whether or not cir...

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...

the preferred colour for surimi is white, but surimi prepared from light fillets of common carp (cyprinus carpio) is slightly pink. hydrogen peroxide (h2o2; 1-3% v/v) with and without sodium tri-polyphosphate (stp; 1-2% w/v) was added to a sodium carbonate bath (ph 7.0-11.5) resulting in a final ph range of 4.4 to 10.1 which was injected into carp fillets. after soaking and tumbling for 30 min ...

Toxicity of the herbicides like 2, 4-D NA salt, glyphosate and paraquat were tested, fish was investigated in laboratory and toxicity tested with common carp. Median lethal concentrations were determined in acute tests. The 96 h LC50 value was 100, 86 and 26 mg/L were tested. The experiment was laid out in a randomized block design with four replications. Screening of different herbicides was t...

BACKGROUND Common carp (Cyprinus carpio L.), one of the most economically valuable commercial farming fish species in China, is often infected by a variety of viruses. As the first line of defence against microbial pathogens, the innate immune system plays a crucial role in teleost fish, which are lower vertebrates. Interferon (IFN) regulatory factor 5 (IRF5) is a key molecule in antiviral immu...
