Brook Trout Temperature Range

There is obviously a wide range of temperatures from which to select an appropriate value and best.

Brook trout temperature range. Incipient lethal temperature for brook trout is 253C Fry et al 1946. Their range extends as far south as the Appalachian Mountains in North Carolina and as far west as Minnesota. Period when water temperatures are likely to exceed the lethal limit.

This is a general guideline for. Cutthroats and brook trout feed optimally at slightly cooler temperatures. The temperature that a Brook Trout begins to stress at is 65 and the water temperature at which could be lethal to Brook Trout is 70 degrees.

Once water temperatures drop to 40-49. T he survival range for trout is published at 35 to 75 F 2 to 23 C. 2018-08-27 The optimal feeding temperatures for Brook Trout varies from 44 degrees to 64 degrees.

The disparity between the lethaltemperatureandthetemperaturelimitsseeninnaturesuggests that sublethal temperature effects play a crucial role in limiting fish populations perhaps through their impact on food consumption and growth. For brook trout these limits are generally accepted to be a few degrees lower some sources suggest as low as 65. Water temperatures are the most important factor in Brook Trout habitat.

Some species can live in the pH range of 35 to 98. 2019-01-31 Brook trout spawning behavior is largely dictated by fluctuations in water temperature. And the optimum feeding range for most trout species is between about 50 and 68 F 10 to 20 C.

Temperatures between 55F and 60F are most ideal. Contiguous catchments containing brook trout were dissolved into patches of. They are often found in clean cool mountain streams including the Chesapeake Bay watershed and are most active around dawn and dusk.
