The Adirondack trout requires cold, clean and heavy oxygenated waters to survive. The rising temperatures may influence their habitat, and they may have to face the challenge to adapt to a new environment.
The Brook Trout and the Lake Trout are two coldwater species that can be found in many of the lakes and streams from Adirondack.
The Adirondack trout maintains its body temperature by connecting to the waters it lives in, and it relies on external heat sources. It has low metabolic rates; it needs less energy and survives on less food.
The water creatures select their environments to fit their physiological and biochemical processes. For example, they will not leave the cold waters not even to feed. Younger fish and the mature ones need different environments, so they usually change the location with age. This can lead in time to overcrowding, diseases, and a lower chance of getting food.
The rising temperatures create evaporation and lower water levels, which in turn can lead to algal growth. The bacteria living along with the algae will consume the oxygen in the waters and make them unsuitable for the trout. The Lake Trout will have to move, and the Brook Trout will have to avoid certain areas of the streams.
The changes will be driven by very small temperature rises, even a couple of degrees will make the trout look for more suitable places to live.
The monitoring performed on the Adirondack trout population have already proven that the lakes and the ponds in the area have warmer waters, with increased algae and lower oxygen levels.
The Brook Trout prefers temperatures below 65 degrees F, and it can tolerate for brief periods of time temperatures up to 72 degrees F. If it has to face temperatures over 72 degrees, the trout will die in a matter of hours.
The Lake Trout lives in the lakes of the northern area, and it’s praised as being a game fish and also a tasty meal. The creatures have a slow growing and mature late. They are also very susceptible to overfishing.
The Brook Trout is native to the eastern area, but it had been introduced to other locations too. They can live up to seven years and usually, reach the maximum size of 15.5 inches. Their growth rate depends on the season, the flow rates and the water temperatures. The warm temperatures are stressful for the brook trout.
As for the climate change, the current models predict a 2.5 temperature rise by the end of the century. Even if there is little to be known about the process, the impact on the environment may exceed expectations and be even tougher than imagined.
