Why is the quality of the streamside habitat important for the parr stage?
Answer
Because terrestrial insects fall in from the banks, forming a significant part of their diet
Since a significant component of the parr diet comes from terrestrial insects falling from the banks, the quality of the surrounding streamside habitat is just as important as the water quality for supporting them.
