Salmo salar Transcriptome or Gene expression

Atlantic salmon smolt transferred to the sea for aquaculture, or migrating to the open sea in the wild, are exposed to several infectious and non-infectious challenges that can cause mortality. Exercise before transfer promotes growth, health and survival in the sea. Parr swimming performance is positively associated with resistance to some diseases. Genetic variation is likely to affect how different stock respond to exercise. In this study we used RNA-seq to map genetic changes and differences in the heart associated with aerobic exercise, swimming performance and genetic origin.
