I caught a strange sub spieces of pike

need a picture . How do you know its a pickrel subspecies. Where you at?

I was completely dark green no white belly and yellow spot (discolorment) and a different head (some fishes has another pattern etc).

It had black fins and smelled like rotten carmalized sugar (i still feel sick). Is this something you have to alarm the "nature reserve" about? I also caught a pike perch with a little bit different looks it was brighter. There's also carp fish etc.

You caught it, or found it rotting on a bank?

It hooked my bait a silver spoon bait for bass, pike and trout

actually looks like a musky. catch it in stream or a lake

Yes i wonder if theres a Encyclopedia with latin names. Because i found a page with subspecies for trout but need for pike and Muskie.

Very interesting reading about pike. https://en.wikipedia.org/wiki/Esox

Also the famliy Esox Lucius - what I've found:

Esox Lucius - Description

"..A hybrid between northern pike and muskellunge is known as a tiger muskellunge (Esox masquinongy × lucius or Esox lucius × masquinongy,[6] depending on the sex of each of the contributing species). In the hybrids, the males are invariably sterile, while females are often fertile, and may back-cross with the parent species.[7] Another form of northern pike, the silver pike, is not a subspecies but rather a mutation that occurs in scattered populations. Silver pike, sometimes called silver muskellunge, lack the rows of spots and appear silver, white, or silvery-blue in color.[8] When ill, silver pike have been known to display a somewhat purplish hue; long illness is also the most common cause of male sterility.

It looks like a juvenile muskie to me, a hungry one.

Yes it's probably that way but there s no muskie in the lake but they can also turn yellow from discolorment and be black and yellow according to encyclopedia.

The origin of species, Darwin, geological succession of organic beings, wordsworth, 1998, p. 259

"The dominant species of the larger dominant groups tend to leave many modified descendants and thus new sub-groups and groups are formed. As these are formed, the species of the less vigorous groups, from their inferiority inherited from a common progenitor, tend to become extinct togheter, and to leave no modified offspring on the face of the earth." - Charles Darwin

Crazy!! Army Green yellowed spotted northern pike with a Twisted Beats Chin.
