Are brook trout endangered?
What are three physical adaptations that brown trout have to help them survive?
How does pollution affect trout?
Pollution degrades the habitat of trout by reducing the places where they can reproduce. Nutrient pollution from fertilizers cause algae to bloom and use all of the oxygen in the water, which prevents other fish and aquatic species from living in the stream.

What does a trout need to survive?
Trout need cold water to survive. Cooler water temperature allows water to hold more oxygen. Forested areas along streams and rivers (known as “riparian areas”) provide shade and help to cool the water.
How does global warming affect trout?
Scientists project that for trout and other cold-water aquatic species, the combined effects of a 1.5 degree Fahrenheit increase in average air temperatures could result in a 7 to 16 percent loss of trout habitat in the continental United States.
