In this study, five carp pituitary glands were collected and dispersed enzymatically and mechanically.Then, the cells were cultivated as monolayer in MEM (minimum essential medium Eagle). The culture mediawere collected after 72 h and frozen at -20°C. Carp ovarian follicles also were separated mechanically andincubated in BSS (basic salt solution) Cortland medium in 24-well microplates for 48 h...

BACKGROUND The caspase-associated recruitment domain-containing protein (CARP) is expressed in almost all tissues. Recently, the tumor-suppressive function of CARP was discovered and attracted increasing attention. This study aimed to investigate the role of CARP in the carcinogenesis of human gastric carcinoma. METHODOLOGY/PRINCIPAL FINDINGS Compared with normal gastric tissue, the downregul...

The cabbage butterflies Pieris rapae and Pieris brassicae have unique enzymes, named pierisin-1 and -2, respectively, that catalyze the ADP-ribosylation of guanine residues of DNA, which has been linked with induction of apoptosis and mutation in mammalian cell lines. In the present study, we identified ADP-ribosylation activity targeting DNA in six kinds of edible clam. Similar to our observat...

Pituitary adenylate cyclase-activating polypeptide (PACAP) is a potent growth hormone (GH)-releasing factor in lower vertebrates. However, its functional interactions with other GH regulators have not been fully characterized. In fish models, norepinephrine (NE) inhibits GH release at the pituitary cell level, but its effects on GH synthesis have yet to be determined. We examined adrenergic inh...

Buchtová H. , Z. Svobodová, M. Kocour , J . Vel í‰ek: Evaluation of the Dressing Percentage of 3-year-old Experimental Scaly Crossbreds of the Common Carp (Cyprinus carpio, Linnaeus 1758) in Relation to Sex. Acta Vet. Brno 2006, 75: 123-132. The aim of the present study was to compare dressing percentages, with relation to sex, of three bisexual groups of hybrid carp, i.e. Hungarian mirror carp...

The aim of this study was to investigate the genetic mechanism of the transparent trait in transparent crucian carp. We observed body color development in transparent crucian carp larvae and analyzed heredity of color in hybrids produced with red crucian carp, ornamental carp, and red purse carp. The results showed that the body color of the newly hatched larvae matured into the adult pattern a...

BACKGROUND Single nucleotide polymorphisms (SNPs) have been used as genetic marker for genome-wide association studies in many species. Gene-associated SNPs could offer sufficient coverage in trait related research and further more could themselves be causative SNPs for traits. Common carp (Cyprinus carpio) is one of the most important aquaculture species in the world accounting for nearly 14% ...

silver carp is the major specimen in warm water fish culture system in iran which is presented in various size and different price. the present study was aimed to compare nutritional value and to investigate proportion of nutritional value and financial of various weight groups of silver carp in spring season. for this purpose silver carp was prepared in market sizes and their dry matter, fat, ...

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...

A lethal disease of koi and common carp (species Cyprinus carpio) has afflicted many fish farms worldwide since 1998, causing severe financial losses. Morbidity and mortality are restricted to common carp and koi and appear in spring and autumn, when water temperatures are 18 to 28 degrees C. We have isolated the virus causing the disease from sick fish, propagated it in koi fin cell culture, a...
