Two koi (Cyprinus carpio) from the same pond developed similar lesions of scoliosis. Radiographic examinations showed that their spines had become malaligned as a result of vertebral compression fractures involving T14 to T16. The vertebrae in both fish were stabilised with screws, k-wire and polymethylmethacrylate. They both appeared to improve after surgery, but they began to decline and died...

The current study was carried out to investigate the effects of dietary supplementation lysine and methionine on growth performance, approximate carcass compositions haematological biochemical parameters in common carp, Cyprinus carpio fingerlings (average weight 22 ± 0.9 g) for 10 weeks. Four experimental diets were prepared with supplemented at levels (0 (control diet), T1 (1Lys 0.4Met g/kg),...

the boojagh international wetland with a surface area of 80 hectares and 25 fish species is located in the southwest shores of the caspian sea (guilan province, iran), but there is no report about fish parasites in this wetland. in the present study, a total of 553 individuals of 8 fish species including cyprinus carpio (n=71), abramis bjoerkna (n=153), carassius auratus gibelio (n=89), esox lu...

DNA fragments related to the cloudy catshark Scyliorhinus torazame L-gulono-gamma-lactone oxidase (GULO) cDNA were detected in a distant fish species. Although the Southern hybridization pattern was more distinct in species with active GULO, DNA fragments related to the GULO gene were also discovered in the common carp Cyprinus carpio. Additionally, in the common carp, inter-individual variatio...

The aim of this study which was carried out from March 2003-February 2004 was to determine the parasites of carp (Cyprinus carpio L., 1758) inhabiting the Kovada Lake. During the study, a total of 63 common carps were caught in different regions of Kovada Lake each month and investigated parasitologically. In carps, the ectoparasite, Dactylogyrus minutus of Monogenea, was found and endoparasite...

This report documents 2 cases of branchioblastomas in koi carp (Cyprinus carpio). Macroscopically, both cases were characterized by well-demarcated, pale red nodular masses located at the left first branchial arch and the right pseudobranch, respectively. Histologically, the neoplasias were composed of blast-like cells that differentiated into cartilage and branchial lamellae embedded in abunda...
