Neon Green Pike

Does anyone have a hypothesis as the how this could come about?

Ate one too many glowsticks.

Mine is on it's eating habits.

Sylvan has a wide range of Pike colours depending on where you catch them, from standard green, to an almost white, to a black.

Swan Lake I see something similar. Many of the Pike caught there are an almost emerald green - not like I've seen on any other Pike anywhere, but at the same time, have caught others in the same water that appear to be a normal colour.

Either way, wicked catch!

Cool ....

Similar to Greenbacks (Walleye) out east - that are missing some of the common primary pigments due to a genetic issue this pike may have more/some missing. Pigmentation can cause some tissue in fish to appear "UV bright".

UV bright pigmentation called iridophores - which are iridescent and reflective are present, in small quantities on Pike.

Just a guess based on a reasonably plausible, but very, very rare, condition that effects many types of fish. Having this much pigmentation lost would be a super rare event.

That's just my kick at the cat.

:lol: He is pretty much the same colour as one.

I did not know pike could be that colour. It could be a combination of what they're eating, and what EZM suggested below . . .

That is really interesting.

I have a bearded dragon with hypomelanism: he has very limited black pigment and his colours are a combination of muted and quite bright (almost neon orange in some places).

An emerald green pike from Swan Lake with hypomelanism might look a lot like the neon green pike from Great Slave Lake.

According to this article http://dev.biologists.org/content/140/14/2997.full "iridophores attract xanthophores, whereas xanthophores repel melanophores.'

An abundance of iridophores could result in a lesser quantity of malanophores, thus resulting in a pike with less black pigment (like my hypomelanistic bearded dragon). The lack of black pigment could make the emerald green appear much brighter: especially in areas where there isn't a huge amount of black pigment to begin with.

I checked the regs for Great Slave Lake . . . another article indicated they were fishing in the "North Arm." The daily limit is 3 Norther Pike with no size limits or other conditions (unless I missed something).

I might have had a really hard time talking myself out of "bonking" that one. On one hand, I'm totally thrilled that the anglers didn't bonk it . . . but on the other hand the geek in me really wants to know what is up with that fish.

Ate too many dyed baits

I like the glow stick theory. Or he's a Rider's fan.
