I caught a brownie today that had just a smattering of spots and none were red. My mind’s indelible trout, my biggest brown thus far, had innumerable black spots, crammed together so that many were not even round anymore, along with splashy red ones.
What factors figure into a brown’s pattern? Is one more influential than another?
Also, I know that they may change at breeding time, but isn’t that just in intensity of color? Just the males?
This is not what you meant – but red spots appearing on a brown trout’s adipose fin is a strong indication of wildness. Stocked browns do not have those spots unless they have been in the stream for some years.
It has something to do with the trout’s diet in the wild, or so I’m told by a very good authority.
