So you think these big mature males don't silver up like the other smaller browns?
I was referring to them catching them “only in the spring”. I don’t think they go out deep to find them in the summer.For the coloration, you got me. I have always assumed it had more to do with what they eat or the water color, but you would know better than I.
It does have to do with what they eat and water color, however out here in the Great Lakes in the spring the browns tend to be silvery like the following one and they don't start getting color until late summer into fall. The first picture I posted looked like a fall spawning male to me. But like I said maybe once they get to certain age and size they don't silver up anymore? Hopefully someone can chime in that has more experience than I do, especially our Lake Ontario anglers.
Zwiggles I wonder if those huge brown stay inshore all year and dine on gobies? The water doesn't get exceptionally warm does it? My trout pond gets into the upper 60's F when we get a heat wave, and it doesn't bother the browns at all. In fact the brook trout can handle it too as long as it's a gradual increase and there is enough D.O.
