Anyone Tell Why This Brown Looks So Different?

[kglissmeyer]

As I was managing some of my photos the other day I realized that there were some stark differences in coloration of fish from different waters, but then I saw something I have never seen in Brown Trout coloration, with the exception of a closely related Hybrid - the Tiger Trout.
So, I have posted several pictures of varied colored Browns, with the odd one with the vermiculations not normally found on Brown Trout posted last.
Comments?

Lower Henry's Fork Brown:



Snake River Spring Creek Brown:



South Fork Snake Brown:



The Odd Man Out Brown from a favorite spring creek (notice the vermiculation like on a tiger or brook trout - neither of which is in this drainage):



Anyone have some ideas, or is it just due to diet and location?

I posted a question a while back about a brown without the halo around the spots. I think you caught it. I wonder how it got to Idaho from the Mojave River? HMMM. That's unusual markings for sure. Jim

I just found one more that's just as odd - almost no spots:



I guess people all look different too.

They look very different to me because they are all way bigger than any browns I have caught recently. Mine tend to be in the 8"-12" size. Must be a totally different species. 8T

Kelly,

Are Tiger Trout sterile? If not, you could be seeing a natural occuring hybrid of a hybrid.

There is another strain of German Browns that came to us from Germany through Scotland. They were planted in many of the lake of the North West and they proliferated very well. My Dad used to call them Lock Laven because they came to us from a lake in Scotland called Lake (Lock) Laven. They don't have the bright yellow color with the punctuated dots. But the characteristics are still familiar. Here's a pic of one from Medical Lake near Spokane Washington.


Sorry for the lousy pic, but the dots don't have the same halo and those from the Snake River in Idaho.
