If you are wondering whether the reason why fish do not need to breathe the air the way humans do, is because there is oxygen in their food, that's not how it works. Fish obtain oxygen from the water, through their gills. Food does not contain any significant amount of free oxygen although it certainly contains compounds that are made with oxygen, such as water (H2O).
