Molecular characterization of the myxosporean associated with parasitic encephalitis of farmed Atlantic salmon Salmo salar in Ireland.
During seasonal epizootics of neurologic disease and mass mortality in the summers of 1992, 1993 and 1994 on a sea-farm in Ireland, Atlantic salmon Salmo salar smolts suffered from encephalitis associated with infection by a neurotropic parasite. Based on ultrastructural studies, this neurotropic parasite was identified as an intercellular presporogonic multicellular developmental stage of a hi...
متن کاملAspects of the epizootiology of pancreas disease in farmed Atlantic salmon Salmo salar in Ireland.
A computerised database containing information on over 17.8 million salmon contained within 49 separate marine populations was used to study the epidemiology of pancreas disease (PD) in Ireland. Of the 43 recorded PD outbreaks, 57% occurred in the 3 mo period August to October inclusive (17 to 32 wk post-transfer). Analysis of variance of mortality rates during PD outbreaks occurring on 6 marin...

In North America non-anadromous forms occurred throughout most of the species’ historical range, as far west as Lake Ontario, and remain ...
متن کاملEstimation of direct costs associated with cataracts in farmed Atlantic salmon (Salmo salar)
A spreadsheet model that has been standardised for use across different livestock species and diseases, was utilised to estimate the direct costs of cataracts in farmed fish, using the Norwegian farmed salmon industry segment as an example. The data input for the model was obtained from previously published information and also from a small survey specifically carried out to obtain the addition...
متن کاملDiseases of farmed Atlantic salmon Salmo salar associated with infections by the microsporidian Paranucleospora theridion.
The microsporidian Paranucleospora theridion was discovered in Atlantic salmon Salmo salar suffering from proliferative gill disease in a marine farm in western Norway in 2008. The parasite develops in cells of the reticuloendothelial system, cells important for normal immune function. The aim of this study was to see if P. theridion could play a part in some of the diseases with unclear causes...
