Spatial and non-spatial risk factors associated with cage-level distribution of infectious salmon anaemia at three Atlantic salmon, Salmo salar L., farms in Maine, USA.
The distribution of infectious salmon anaemia (ISA) was examined among 80 cages from three Atlantic salmon grow-out farms in Maine, USA that were stocked with smolts from a single hatchery. Cage-level disease was broadly defined as one or more moribund fish testing positive for infectious salmon anaemia virus (ISAV) by RT-PCR and a second confirmatory test (IFAT, culture or genotype sequence). ...
متن کاملThe Epidemiology of Hemorrhagic Kidney Syndrome - Infectious Salmon Anemia in Atlantic Salmon in Atlantic Canada
Hemorrhagic Kidney Syndrome (HKS) is characterized by high mortality rates in Atlantic salmon seawater sites with unique histological kidney lesions. Virus isolation results were positive for the orthomyxovirus responsible for Infectious Salmon Anemia (ISA) experienced by Norway and also a new virus tentatively classified in the Togaviridae family was isolated in some, but not all outbreaks. Th...

Sablefish aquaculture is a topical issue in BC due to the prospect of a major sablefish hatchery planned for Salt Spring Island, which would produce juveniles for the intended BC industry. This report analyzes available informati...
متن کاملIsolation of infectious salmon anemia virus (ISAV) from Atlantic salmon in New Brunswick, Canada.
Infectious salmon anemia virus (ISAV) was isolated at a marine grow-out site in New Brunswick, Canada, from Atlantic salmon Salmo salar which experienced mortalities due to hemorrhagic kidney syndrome (HKS). Of 20 fish sampled in this study, 14 showed histologically various degrees of interstitial hemorrhaging, tubular epithelial degeneration and necrosis, and tubular casts in the posterior kid...
متن کاملSpatial distribution of heavy metals in soil, water, and vegetables of farms in Sanandaj, Kurdistan, Iran
BACKGROUND Heavy metals are ubiquitous elsewhere in nature and their measurement in environment is necessary to develop health management strategies. In this study, we aimed to find out concentrations and spatial patterns of heavy metals in main farms of Sanandaj in Kurdistan, Iran. METHODS Over May to October 2012, six farms were selected to analyze concentrations and spatial patterns of sev...
