this study was conducted to evaluate the effects of different proportions of lemon bee brush essential oil on growth performance, carcass composition, and hematology and biochemical parameters of common carp (cyprinus carpio). common carp with an average weight of 8 ± 0.2 g were fed for one month with a diet supplemented with lemon beebrush essential oil (0.15 and 0.3 ml) and with normal diet a...

kruppel-like factors (klfs) are a highly related zinc-finger family of transcription factors implicated inthe regulation of the eukaryotic cellular growth and differentiation of a diverse set of cells in mammal. usingrt-pcr technique, a 456 bp cdna fragment encoding n-terminus part of a klf2b was isolated from the skinmucosa of common carp (cyprinus carpio) using two degenerative oligonucleotid...

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...

Some biochemical characteristics of common carp (Cyprinus carpio) and silver carp (Hypophtalmichthys moltrix) surimi prepared by a conventional washing method and protein isolated using alkaline-acid-aided processes were investigated. Solubility of protein in silver carp and common carp were found to be highest by using the conventional washing method. Decreases in myoglobin and lipid contents ...

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...

Polybrominated diphenyl ethers (PBDEs) are hydrophobic organic contaminants with properties and nomenclature similar to polychlorinated biphenyls (PCBs). While much information is available on the bioaccumulation and pharamcokinetics of PCBs, little information is available on PBDEs. In this study, juvenile carp were exposed to a diet spiked with a cocktail of four BDE congeners (2,4,4'-tribrom...

—The silver carp Hypophthalmichthys molitrix has spread throughout the Mississippi River drainage. During 2003, we determined its population status and potential impact in the middle Mississippi River (MMR), the conduit between the lower Mississippi River and the upper Mississippi, Missouri, and Illinois rivers. We quantified growth, age structure, fecundity, and diets of silver carp sampled wi...

Jackson ZJ, Quist MC, Downing JA, Larscheid JG. 2010. Common carp (Cyprinus carpio), sport fishes, and water quality: Ecological thresholds in agriculturally eutrophic lakes. Lake Reserv. Manage. 26:14–22. We examined fish populations, limnological conditions, lake basin morphology and watershed characteristics to evaluate patterns in population characteristics of ecologically important fish sp...

The varieties of carp we mentioned before are all hybrids. The traits of the offspring of the hybrid carps will be segregated. So new hybrids should be made every year and at least two varieties of parental fish must be conserved in order to obtain the hybrid carps. This can be inconvenient in practice. Jian carp is the first variety of common carp that was produced by artificial breeding in Ch...
