So I have been reading all along that fish go deeper in the winter and have been thinking that they do this for two reasons. Water temps and DO. However, it seems as if water temp is the most important thing and DO just happens to be there. Does a fish go into their temperature zone and will not pursue DO outside of that zone when it runs out? It would rather suffocate than be to cold/hot?
Have read this on DO and thermocline.
