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...

Interbreeding between artificially-selected and wild organisms can have negative fitness consequences for the latter. In the Northwest Atlantic, farmed Atlantic salmon recurrently escape into the wild and enter rivers where small, declining populations of wild salmon breed. Most farmed salmon in the region derive from an ancestral source population that occupies a nonacidified river (pH 6.0-6.5...

Composite culture of edible fishes (common carp, Cryprinus carpio; silver carp, Hypopthalmithys molitrix, grass carp, Ctenopharyngodon idella; catla, Catla catla; rohu, Labeo rohita; and mrigal, Cirrhinus mrigala) in rice fields in the Cauvery delta of Tamil Nadu, southern India, resulted in 81.0% reduction in the immature mosquito population of anophelines and 83.5% of culicines. Analysis of f...

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...

A recently reported mRNA, encoding 'carbonic anhydrase-related polypeptide' (CARP) from the Purkinje cells of mouse cerebellum, was shown to have a 30-40% deduced amino acid sequence identity with the carbonic anhydrases (CA) of mammals. In order to compare the mouse and human CARP sequences, we used the polymerase chain reaction (PCR) to amplify human CARP sequences from several cDNA libraries...

Background: Motile Aeromonas species cause heavymortalities in carp farms during spring and summer in Iran. Objectives: The aim of this study was to detect phenotypicand genotypic characterization of motile Aeromonas species isolated fromdiseased carps in some northern and southern provinces of Iran. Methods: A number of 40 samples from 22 fish farms werecollected. The identified motile Aeromon...

INTRODUCTION In rheumatoid arthritis (RA), several genetic risk factors and smoking are strongly associated with the presence of anticitrullinated protein antibodies (ACPA), while much less is known about risk factors for ACPA-negative RA. Antibodies against carbamylated proteins (anti-CarP) have been described in both ACPA-positive and ACPA-negative RA patients. In this study, we have analysed...

Farmed Atlantic salmon (Salmo salar) from Maine and eastern Canada, wild Alaskan Chinook salmon (Oncorhynchus tshawytscha), and organically farmed Norwegian salmon samples were analyzed for the presence of polychlorinated biphenyls (PCBs), dioxin-like PCBs, polychlorinated dibenzo-p-dioxins (PCDDs), dibenzo-p-furans (PCDFs), and chlorinated pesticides. PCDD and PCDF congeners were not detected ...

There is evidence that n-3 fatty acids (FA), especially EPA and DHA, are beneficial for human health. This thesis examined factors influencing FA composition in common carp flesh, sought to develop a procedure for long-term sustainable culture of common carp with improved muscle lipid quality (omega 3 carp) and studied the health benefits of eating such carp in the secondary prevention of cardi...
