With summer water temperatures rising well into the 70s, what are the water temperatures that you definately will not fish for: Brown Trout, Brook Trout and Rainbow Trout. IMHO, we, in this part of NY State will have to rely on self policing to give the fish a break!

In the early 60s, I remember reading about a gentleman (I think that it was in Oregon) studying the effects of temperature and oxygen levels on Trout. As I remember it he wanted to see what the fish could tolerate with a eye toward actually raising the tolerance level of the fish. Its been a long time since but I think his method was to slowly raise the temperature at various oxygen levels keeping track of these data for analysis and observing the effect on the fish. The first stressed were removed from the sample and the last were allowed to spawn and the progeny had the same experament done on them. The hope was that a race of fish would evolve that was more warm water tolerant.

I don't know the results and never heard any more of it. anyone know?
