The present study was conducted on two species of cyprinid fish: Common Carp (Cyprinus carpio) and grass (Ctenopharyngodon idella). includes the effect increasing salinity survival rate, oxygen consumption, glucose total protein levels in blood plasma, energy usage, food consumption growth rate. carp show more resistance to with 90% rate 15 g/l salinity. While did not survive than 5 g/L. Increa...

Although horizontal cells encode chromatic information by means of a variety of spectrally opponent light-evoked response patterns, their synaptic connections with the different spectral classes of cone are not completely understood. In the cyprinid fish retina, where a hierarchical set of interactions between horizontal cells and cone types has been proposed, a particular type of horizontal ce...

To increase public health awareness for prevention of opisthorchiasis caused by eating raw freshwater fish, the distribution and abundance of Opisthorchis viverrini metacercariae (OV MC) was investigated in freshwater fish obtained from 20 provinces in northeastern Thailand between April 2011 and February 2012. A cross-sectional survey was conducted on 12,890 fish consisting of 13 species rando...

Fish are important elements of aquatic ecosystems. Their communities naturally follow the river continuum and have been well described in western European freshwater watersheds. In regions higher endemism, such as Balkan Peninsula, widely accepted fish zonation Illies is doubtfully relevant. this study, a more suitable categorization lotic lentic ecosystems Bulgaria proposed, based on 389 multi...

Spring viremia carp virus (SVCV) is a rhabdovirus seasonally affecting warm-water cyprinid fish farming causing high impacts in worldwide economy. Because of the lack of effective preventive treatments, the identification of multipath genes involved in SVCV infection might be an alternative to explore the possibilities of using drugs for seasonal prevention of this fish disease. Because the zeb...

Mitochondrial homoplasmy signifies the existence of identical copies of mitochondrial DNA (mtDNA) and is essential for normal development, as heteroplasmy causes abnormal development and diseases in human. Homoplasmy in many organisms is ensured by maternal mtDNA inheritance through either absence of paternal mtDNA delivery or early elimination of paternal mtDNA. However, whether paternal mtDNA...

Carp interstitial nephritis and gill necrosis virus (CNGV) is an unclassified large DNA virus that morphologically resembles members of the Herpesviridae but contains a large (ca. approximately 280-kbp) linear double-stranded DNA. This virus has also been named koi herpesvirus, koi herpes-like virus, and cyprinid herpesvirus 3. CNGV is the cause of a lethal disease that afflicts common carp and...

In April and June 2014, mortalities of goldfish occurred at Korea. The principal signs included pale gills, severely enlarged softened spleen kidney red liver. Moreover, the histopathological characteristics observed mainly in hematopoietic tissues kidney, gill lamellae intestine. predominant changes were severe necrosis tissue. addition, nucleus exhibiting peripherally displaced chromatin part...
