Cod are a very lethargic fish as they are pelagic (on the bottom) and their body style is not built for speed at all. Their muscle is composed entirely of white muscle which is why they are so valuable as a fishery. White muscle is designed for very short quick bursts of speed to catch food or to evade a predator.
