Extremely unlikely. First of all because they normally feed in shoals, groups of 20, 30, 40, 50 different fish that all vary in size. And they generally follow herring, anchovy or sardine shoals themselves, where they can maximize their feeding. That means that a floating body would not be very tasty for a tuna.
