The picture I recently posted is actually a musky, darker earlier season colour on this younger fish but indeed a barred pattern musky not the hybrid version tiger musky.
Charts like this that can be found on the internet will assist fisherman who are unfamiliar with musky in general, knowing what you have caught and how to correctly identify it is a crucial part to fishing.
Indicators like a rounded tail or fins placed differently are thing to look at, in this case you can see in the picture I posted that the fish my friend caught is the barred pattern musky, tail is sharper/pointed not rounded.
I have reviewed my share of charts as there are some hybrid versions of fish that do resemble the regular species.
