“The annual catch of brook trout and Atlantic salmon, however, is experiencing a relatively steady decline for a multitude of reasons; over-exploitation, habitat degradation, and the introduction of invasive species such as the smallmouth bass, for example, can account for some of this deterioration. In addition, brook trout are extremely sensitive to temperature-related stress and are intolerant to water temperatures above their thermal optima, which in general, is relatively low for salmonids.”
