Abstract: In order for a fish to grow and thrive, the gut must function efficiently. This is achieved through a range of processes, including controlled patterns of gut motility and modifications in gut blood flow. How these processes are affected by long and short-term changes in ambient temperature was the main focus of this thesis. After acclimation to a higher temperature, the interdigestive motility of rainbow trout was higher. This indicates an increased demand for movements involved in the houseke... more
