Rainbow trout (Oncorhynchus mykiss) head kidney phagocytes precultured with a synthetic cytidine-phosphate-guanosine (CpG) oligodeoxynucleotide (ODN) displayed significantly higher phagocytic activity against Vibrio ordalii than phagocytes precultured with non-CpG ODN. However, head kidney phagocytes precultured with CpG ODN did not show enhanced phagocytic activity against polystyrene particles.

the aim of this study was to determine the effect of propolis and pollen extract on biochemical and haematological parameters of onchorhynchus  mykiss. one hundred and eighty healthy fish, o. mykiss (mean weight 20.57±4.48 g) were used for growth performance and haematological assays. they were randomly selected, and distributed among fifteen 600-l fiberglass tanks as three treatments (1% polle...

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...

In this study, the effects of photo-electrocatalysis (PEC) were evaluated as an innovative application conventional photocatalysis (PC) to remediate water in a recirculating system for rainbow trout (Oncorhynchus mykiss) culture, relation fish welfare and health, with multidisciplinary approach. Three tanks employed, equipped biological filters control system, three PEC purification system. The...

Semelparous Pacific salmon (Onchorynchus spp.) serve as an excellent model for examining the relationships between life history, behavior and individual variation in glucocorticoid (GC) stress hormone levels because reproductive behaviors are highly variable between individuals and failure to reproduce results in zero fitness. Pink salmon (O. gorbuscha) were intercepted upon arrival at the spaw...

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.
