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...

The simultaneous quantification of several transcripts via multiplex PCR can accelerate research in fish physiological responses to diet and enable the development of superior aquafeeds for farmed fish. We designed two multiplex PCR panels that included assays for 40 biomarker genes representing key aspects of fish physiology (growth, metabolism, oxidative stress, and inflammation) and 3 normalizer genes. We used both panels t...
