i had a bit of time before work and got an 18" trout and 25" redfish around low tide, however i noticed something different about the red i havent seen on any ive caught before…its tail was almost electric blue when the sun hit it. couldnt get the worlds greatest pic with a cell phone to show it but im guessing it gets the blue pigment from eating a lot of blue crab or shrimp?
Came across this online:
Due to the bluish tint of the cyanobacteria (algae) in the water. It works it’s way up the foodchain through the herbivores (shrimp) and into the body of the redfish. The color is expressed (shown) through the tail as this is where the chemical somehow gets located.

Indeed. It is true that they get this from a good number of shrimp in their diet. It seems a lot more noticeable in the fall, at least in my experience. Nice red though!

Was told by DNR that it’s from the diet…but…It is triggered by a fish that has been very aggressive or scared.

bioaccumulation of blue green algae from shrimp to redfish definately makes sense too thanks! i was working one area and saw a quite a disturbance in another pocket of water so tossed my jig there it smacked my jig like crazy and put up a pretty hard fight so assuming what cooper river mans saying is true im going with aggressive lol. then again flippers been out in full force too!
Always cool to here the internet analysis about why and when and what and…
I would be just as happy looking at the fish pictures with NO words, as I am at watching the local weather reports with the sound turned OFF!!
Great pictures, OhioNavyNuke.

That must really help…

Oh yea and nice red by the way! Love the blue tails!

predators higher up the food chain (like reds) bio-accumulate many things from lower in the food chain (from primary producers like invertebrates, copepods, spartina, smaller fishes etc) like heavy metals such as mercury and algae like cyanobacteria. i can only guess this animal bio-accumulated some sort of photosynthetic organism and it for some reason settles and shows in the caudal fin
EDIT: just saw the question was answered already
