The original description of Myxobolus longisporus Nie et Li, 1992, the species infecting gills of Cyprinus carpio haematopterus L., is supplemented with new data on the spore morphology and pathogenicity. Spores are elongate pyriform with pointed anterior end, 15.7 (15.5-16.5) microm long, 6.7 (6-8) microm wide and 5.5 microm thick. Sutural ridge is straight and narrow. Mucus envelope is lackin...

Calpastatin, an important protein used to regulate meat quality traits in animals, is encoded by the CAST gene. The aim of the present study was to clone the cDNA sequence of the CAST gene and detect the expression of CAST in the tissues of Cyprinus carpio. The cDNA of the C. carpio CAST gene, amplified using rapid amplification of cDNA ends PCR, is 2834 bp in length (accession No. JX275386), c...

The present study attempts to identify some of the differences between skull bones two species Cyprinus carpio and Carassius carassius, which belong Cyprinidae family. is a taxonomic diagnostic are considered local fish abundant in Iraqi aquatic environment

In 5 experunents, conlmon carp fry Cyprinus carpio with Dactylogyrus vastator infection of varying severity, as well as parasite-free fry, were placed into an environment of decreasing oxygen content. The correlation between the time of death and helminth infestation of the gills was studied. The experiments demonstrated that in a medium of decreased oxygen content the carp with the heaviest he...

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 karoun river is major source of water for warm water fish culture industry in southwest of iran. the aim of the present study was to investigate the distribution of mercury in tissues of marketable common carp and in bottom sediments of fish farms in khouzestan province. this study was carried out on 45 fish farms that are located on the bank of the karoun river in khouzestan province, sout...
