During the farming of juvenile rainbow trout (Oncorhynchus mykiss), losses can be very high. In aquaculture, various agents are used, such as copper, for purpose preventive action and prevention appearance pathogens (ectoparasites, etc.). The aim this study was to determine effects substrate-fixed copper microparticles on growth survival mykiss) up age 5 months. experiment conducted in Laborato...
The development of oil and gas production together with the fruit in nearby areas North Patagonia, Argentina, suggests aquatic pollution scenarios which include permanent combined short events pesticides application. It has been reported that hydrocarbons activate aryl hydrocarbon receptor (AhR) pathway rainbow trout, Oncorhynchus mykiss, insecticide Chlorpyrifos (CPF) interacts these effects. ...
TWO STRATEGIES HAVE BEEN PROPOSED TO AVOID NEGATIVE GENETIC EFFECTS OF ARTIFICIALLY PROPAGATED INDIVIDUALS ON WILD POPULATIONS: (i) integration of wild and captive populations to minimize domestication selection and (ii) segregation of released individuals from the wild population to minimize interbreeding. We tested the efficacy of the strategy of segregation by divergent life history in a ste...
We report here the genome sequences of three Flavobacterium psychrophilum strains causing a bacterial coldwater disease (BCWD) outbreak, isolated from infected rainbow trout from hatcheries in Montana and South Dakota. The availability of these virulent outbreak-causing strain genome sequences will help further understand the pathogenesis of BCWD.
The aim of this study was to establish whether two lines of rainbow trout divergent for their plasma cortisol response to a standardized stressor would show consistent differences in their behavioural response to a range of challenging situations. Our results show that the high- and low-responding (HR and LR) lines of rainbow trout did not differ in the aggression shown towards an intruder or i...
We report here the draft genome sequence of a lethal pathogen of farmed salmonids, Piscirickettsia salmonis strain AUSTRAL-005. This virulent strain was isolated in 2008 from Oncorhynchus mykiss farms, and multiple genes involved in pathogenicity, environmental adaptation, and metabolic pathways were identified.
Novel Weissella sp. bacteria have recently been reported to be associated with disease outbreaks in cultured rainbow trout (Oncorhynchus mykiss) at commercial farms in China, Brazil, and the United States. Here we present the first genome sequence of this novel Weissella species, isolated from the southeastern United States.
approved:__________________________________________________ Carl B. Schreck The extent to which stressful events are maladaptive or adaptive to the long-term survival of fish remains to be better understood. The aim of this study was to identify differentially expressed genes in the livers of rainbow trout, Oncorhynchus mykiss, responding to an experimental stressor. Gene expression responses w...
