The fillet yield phenotype is a trait that can be improved in aquaculture species through conventional selective breeding. This approach was applied to rainbow trout for three consecutive generations of selection to produce a high-yield line (HY) that exhibits 2.5 percentage points higher fillet yield compared to a low-yield line (LY). To characterize the genetic and physiological mechanisms contributing to the HY phenotype, t...

Flavobacterium psychrophilum , the causative agent of bacterial cold water disease (BCWD), is one of the leading pathogens in rainbow trout ( Oncorhynchus mykiss ) aquaculture. To date, there is little knowledge of the transmission kinetics of F. psychrophilum over the course of infection. In particular, how transmission is affected by host genotype and pathogen exposure dosage are not well studied. In order to fill in these k...
