Brook Trout Water Temperature

A safe rule of thumb is that 70F represents the dont fish.

Brook trout water temperature. 2018-08-27 Studies vary on the overall lethal water temperature that will cause a Brook Trout to die. Just a couple of degrees increase in temperature impacts Brook Trout. 42F Lower end of optimal water temperature for Midge hatches.

45F Optimal temperature for Chironomid hatches. However I have caught brook trout at 33 degree water when fishing through the ice. Once water temperatures drop to 40-49.

2020-07-15 Trout feed most actively in water temperatures from 52 to 64 degrees F. 2014-10-29 46F Optimal Brown trout spawning temperature. C or so they become uncomfortable for the brookies to live in.

2019-03-19 Although the brook trout or salvelinus fontinalis as they are known scientifically are a cold-water species by nature a later than usual spring thaw can create problems for anglersmaking these beautiful fish extremely tough to catch. This coupled with the already reduced habitat connectivity from undersized or perched culverts could have a significant impact on our native Brook Trout. Of course these are merely guidelines.

Contiguous catchments containing brook trout were dissolved into patches of reproducing brook trout habitat. Understanding cold early conditions and how to overcome them will put a lot more trout in your creel this spring. You should also take special precautions to protect the fish in extreme conditions when the water is very cold and icy or when its over 70 degrees.

For example temperature limits for Atlantic salmon feeding positive growth are between 70. I am doubtful about the reported optimum feeding temperature ranges for trout. Likewise the shallow lily pond bays that had trout in the spring become brook trout deserts due to decreased oxygen and heat.
