Catfish and carp require lower levels of oxygen than trout. Since the mouth of a river typically has lower levels of oxygen and the area near the source has higher levels of oxygen, catfish and carp can thrive at the mouth and trout, which require higher levels of oxygen, thrive at the source.

Yes. tons of life. near the mouth is archeabacteria. then you have crabs and tube worms and other life.
