There are a few ideas on why Redfish tails are blue. Some say its a sign that they're actively feeding....... eating crabs / blue-green algae accumulated from their diet........ and I've heard it's oxygen flow to their tails when moving around. When I have more time I'll research it a little more to see if I can find definitive studies -- I'm headed to Calabash to fish with college students today!
