Osteocalcin (bone Gla protein) is an extracellular matrix protein synthesized by osteoblasts that is a marker of bone. Osteocalcin probably originated in the ancestors of Teleostei or bony fish and of the Tetrapoda or amphibians, reptiles, birds, and mammals. We have characterized the Cyprinus carpio (carp) osteocalcin for mineral binding to hydroxyapatite, amino acid sequence, and extent of se...

Five exotic carp species viz. Hypophthalmichthys molitrix, Cyprinus carpio var. specularis, Cyprinus idellus, Cyprinus carpio var. communis and Puntius gonionotus were examined for parasitic diseases out of which 793 fishes were infected by 3 protozoan (Trichodina sp., Ichthyophthirius sp. and Chilodonella sp.), 2 monogenean (Gyrodactylus sp., Dactylogyrus sp.), 2 trematoda (Gorgotrema sp., Met...

The Common carp, Cyprinus carpio was exposed to sublethal concentrations of chromium for various exposure periods (8, 16, 24 and 32days). Serum glucose, total protein, total cholesterol, serum GOT and GPT were measured both in control and experimental fish. During various exposure periods (8, 16, 24 and 32 days), the levels of serum glucose, total cholesterol, GOT and GPT levelss were (P<0.05) ...

Androgenesis involves the development of an organism with only paternal chromosomes. The induction of androgenesis using diploid sperm, highly effective UV-irradiation of egg, dispermy using heterologous eggs, the possibility of producing supermales for all male production and the recovery of cryopreserved sperm are recent technological developments in androgenesis in fish. However, few researc...

Carp (Cyprinus carpio), a freshwater fish that lives in a low-calcium environment, and Atlantic cod (Gadus morhua), a seawater fish that lives in a high-calcium environment, were studied for the presence of a novel membrane binding protein ("receptor") for the vitamin D metabolite, 1,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)]. Basal lateral membranes from enterocytes of either species were prep...

The Sanandaj Gheshlagh Reservoir (SGR) is a mercury polluted lake that is located in the West of Iran. Common carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix) are the most abundant fishes in the SGR. A total of 48 common and silver carps (24 each) were captured randomly, using 50×6 m gill net (mesh size: 5×5 cm) during July to December 2009. Each month, the levels of accumul...

Cyprinid herpesvirus 3 (CyHV-3) infection in common carp Cyprinus carpio L. and its ornamental koi varieties can induce the severe systemic disease known as koi herpesvirus disease. This disease is characterised by a rapid replication and spreading of the virus through multiple organs and results in a fast onset of mortality (starting on Day 6 post infection) in up to 100% of infected fish. Dur...

Sci., Supplement 1: 62–71 The paper presents a comparative analysis of proximate and fatty acid composition of seven fi sh species from the Danube River including asp (Aspius aspius), common bream (Abramis brama), common barbe...

The purpose of this study was to investigate the improvement of growth in Israeli carp (Cyprinus carpio), and the cross experiment was carried out with two strains of Israeli carp. Four combinations of Israeli carp from Jeonbuk fisheries farm and Songpu mirror carp from Heilong Jiang, China (KK; Jeonbuk ♀ × Jeonbuk ♂, KC; Jeonbuk ♀ × China ♂, CC; China ♀ × China ♂ and CK; China ♀ × Jeonbuk ♂) w...

The biosynthesis and activation of Toll-like receptors (TLRs) requires accessory proteins. In mammals, a number of accessory proteins have been characterized, that can be classified based on their function as ligand-recognition and delivery cofactors, chaperones and trafficking proteins. We identified the homologs in teleost fish genomes of mammalian accessory molecules and show their expressio...
