Angler Catches Neon Pike On Great Slave Lake wrote an article about a Angler Catching a Neon Pike on the Great Slave Lake

Randy Straker was fishing with a friend when he hooked into a 14-pound northern pike on Great Slave Lake “We were about to grab the fish,” Straker told Moose FM. “As it flared up its gills and its mouth opened up, you could see this very fluorescent blue and green.”

“It was quite a bit lighter [in colour] with very definitive green”

“The bottom lip, in particular, was very fluorescent green and the tongue, the side and the top of the mouth was a combination of fluorescent blue and green.”


Straker told Moose FM parts of the back were also greener than normal. He says he’s caught pike with lighter skin and different patterns in the past but this was unlike any fish he’s ever landed.

After his friend, Craig Thomas, snapped a couple of quick photos Straker released the fish back into the lake

  1. A lonely Pike who just happened to be “mine-ding” his own business causes quite the kerfuffle. Throwing the angling world into a tail spin.

    This specimen like all the other technicolor fish mentioned in previous Fish’n Canada blogs, appear to have two things in common concerning their epidermal contradictions. Water condition of their local environment and their forage fish.

    My assumption in this instance has never been more vivid than to concentrate on the chemical components of the water in Great Slave Lake.

    In the article it was stated,
    “I’ve heard of cases where pickerel take on a blue tint and I’ve heard of silvery pike but nothing with this coloration. Of course the first question everyone asked me was if I caught it near the mine,” Straker said with a laugh. “But another theory could be that feeding habits have changed with lower water levels.

    Don’t laugh. Catching such a distinctive fish whether it was near the mine or at some other location, it may not be such a humours matter. Sure like I have been saying, epidermal coloration may be due to what these fish are eating but, I also mentioned how coloration can be an indication of the health of any water body. Chemical compounds, diseases causing bacteria or other such inclusions could have possibly kick started this Pike’s immune system, causing this type of reaction. Remember the reference to the mucus layer in the Blue Walleye.

    Notice also, this so called “Neon Prognosis” is located on the most acutely sensitive areas of the fish, the mouth in particular. There is no speculation necessary. The facts speak for themselves. Abnormal coloration should raise serious concerns.

    I would suggest that fish caught in this particular lake not be consumed until further analysis can be concluded. Yes indeed, this is no laughing matter.

  2. Straker indicated, “Another theory could be that feeding habits have changed with lower water levels.” A strange combination in my opinion. That is not likely to cause such a drastic alteration in epidermal coloration.

    Lower water levels in Great Slave Lake would cause a higher concentration of chemical compounds from the mine or other natural sources in the area. The dilution rate would drop increasing the concentration.

    Unquestionably, a vividly vivacious study in Ichthyology to say the least.

  3. I have done some rooting around the internet and have come up with a very interesting concepts.

    We should all be familiar with the Grade School Science experiment concerning Litmus Paper. The main use of litmus is to test whether a solution is acidic or basic. Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). Neutral litmus paper is purple. Litmus can also be prepared as an aqueous solution [aqueous solution is a solution in which the solvent is water] that functions similarly. Under acidic conditions, the solution is red, and under alkaline conditions, the solution is blue.

    Wet litmus paper can also be used to test for water-soluble gases that affect acidity or alkalinity; the gas dissolves in the water and the resulting solution colors the litmus paper. For instance, ammonia gas, which is alkaline, turn the red litmus paper blue.

    Red litmus contains a weak diprotic acid. When it is exposed to a basic compound, the hydrogen ions react with the added base. The conjugate base, formed from the litmus acid, has a blue color, so the wet red litmus paper turns blue in alkaline solution.

    Litmus can be found in different species of lichens. A lichen is a composite organism that arises from algae living among filaments of multiple fungi species. Lichens occur from sea level to high alpine elevations, in many environmental conditions, and can grow on almost any surface.

    All this could explain the Blue Walleye Phenomenon and the various abnormal coloration of other fish we have heard of lately. A “Litmus Based Test” for water quality as I first suspected, could rightly be associated with the chemical makeup and reaction between the fish and it’s environment. The “Neon Pike” is self explanatory in this case.

    Yup, that old Pike wasn’t showing off. It was just “Mine”-ding it’s own business.
