Outbreaks of koi sleepy disease (KSD) caused by carp edema virus (CEV) may seriously affect populations of farmed common carp, one of the most important fish species for global food production. The present study shows further evidence for the involvement of CEV in outbreaks of KSD among carp and koi populations: in a series of infection experiments, CEV from two different genogroups could be tr...

Prussian carp (Carassius gibelio) are one of the most noxious non-native species in Eurasia. Recently, Prussian carp, a non-native freshwater fish species, were genetically confirmed in Alberta, Canada and have been rapidly expanding their range in North America since establishment. Given their rapid range expansion, there is an increasing need to determine how Prussian carp may impact native s...

Fish mucosal surface is a significant interface for pathogens to infect from an aqueous environment. In addition innate and adaptive immune factors, epithelial cells are considered as physical barrier against microbial invasion. Previously, we identified mammalian CD46-like complement regulatory protein (Tecrem) in teleost detected its expression on derived fin, suggesting physiological role th...

This study observed the captive culture of Carassius auratus and Cyprinus carpio in Potohar region, Punjab, Pakistan. Captive culturing both species was conducted up to one-month post hatchlings. The sample size 180 (90 goldfish 90 koi carp) kept cemented raceways under optimum conditions. period from October 2019 April 2020. natural breeding season for 25th January 5th February end 11th March,...

Introduction Atypical Aeromonas salmonicida is a fish pathogen that causes several diseases in freshwater fish such as goldfish (Carassius auratus L.) (6) and eel (Anguilla japonica) (2), and also seawater fish (5). Since 1996, A. salmonicida infection characterized by the formation of ulcers on the body surface and fins (ulcer disease) has become prevalent in colored carp (Cyprinus carpio koi ...

Although carp is still widely sold and used in its fresh form, a range of value additions may also be observed. It is essential to know the development and management of a carp farm production costs and their evolution. In Iran, warm-water fish farming is based on common, silver, grass, and bighead carps. The carp is easy to rise in hatcheries in very large numbers at little cost, and is distri...

The aim of the study was to estimate the effect of culture conditions and culture site on magnesium (Mg) and zinc (Zn) concentrations in freshwater fish. The study encompassed dorsal muscles in five fish species: common carp (Cyprinus carpio L.), rainbow trout (Oncorhynchus mykiss Walbaum) and Siberian sturgeon (Acipenser baeri Brandt), northern pike (Esox lucius L.) and grass carp (Ctenopharyn...

The aim of the study has been to estimate the effect of culture conditions and a culture site on magnesium (Mg) concentrations in freshwater fish. The study encompassed tissues (blood) and organs (gills, liver, kidney, dorsal muscles) of five fish species: common carp (Cyprinus carpio L.), rainbow trout (Oncorhynchus mykiss Walbaum), Siberian sturgeon (Acipenser baeri Brandt), northern pike (Es...

Koi herpesvirus (KHV) infection is associated with high mortalities in both common carp (Cyprinus carpio carpio) and koi carp (Cyprinus carpio koi) worldwide. Although acute infection has been reported in both domestic and wild common carp, the status of KHV latent infection is largely unknown in wild common carp. To investigate whether KHV latency is present in wild common carp, the distributi...

Thelohanellus nikolskii infection of the common carp (Cyprinus carpio L.) has been a common parasitosis in the Central European fish farms since the first detection of the parasite about 20 years ago. This parasite, introduced from the Far East, causes intensive infection on the fins of fingerlings of the carp subspecies cultured in Europe (European carp, Cyprinus carpio carpio). This infection...
