Infectious hematopoietic necrosis virus; Oncorhynchus mykiss; adults; biopsy; breeding stock; cell culture; females; fins; fish; fish communities; gills; kidneys; mucus; pathogens; skin (animal); spleen
Abstract:
... Nonlethal sampling techniques have previously been evaluated for detection of a variety of viral salmonid pathogens. However, many of these studies have used molecular assays in lieu of widely accepted cell culture techniques to evaluate the sampled tissues. Samples were collected from female steelhead Oncorhynchus mykiss broodstock using three potential nonlethal sampling methods (mucus/skin scra ...

Abstract:
... This study investigated the growth and immune function effects following partial replacement of fish meal with dried testes meal from pink salmon (Oncorhynchus gorbuscha) testes collected from Alaskan seafood processing byproducts. It was hypothesized that the dietary nucleotide content of testes meal may provide an immunostimulatory effect in rainbow trout (Oncorhynchus mykiss). Three diets were ...

Abstract:
... To determine the potential for protection against Flavobacterium psychrophilum infection, a study was conducted where a probiotic, Enterobacter sp. strain C6-6, was delivered to rainbow trout, Oncorhynchus mykiss, via injection. Two separate studies were conducted. In a preliminary study groups of rainbow trout (mean weight, 2g) were either left unhandled or intramuscularly (IM) injected with a st ...

Abstract:
... Flavobacterium psychrophilum is the causative agent of bacterial coldwater disease and can cause significant mortality in salmonid aquaculture. To better evaluate disease prevention or treatment methods for F. psychrophilum in the laboratory, a waterborne challenge model that mimics a natural outbreak is needed. Here we report on the development of a waterborne challenge model for F. psychrophilum ...

Abstract:
... An attenuated strain of Flavobacterium psychrophilum (CSF259-93B.17) has shown potential as a vaccine for prevention of bacterial coldwater disease (BCWD) in rainbow trout, Oncorhynchus mykiss (Walbaum). Because BCWD outbreaks can result in high mortality in other salmonid species, specifically coho salmon, Oncorhynchus kisutch (Walbaum), the live-attenuated strain was tested as a vaccine in this ...
