What seemingly positive change caused by invasive mussels can negatively affect native fish spawning cycles?

Answer

Increased water clarity allows sunlight to penetrate deeper, altering temperature stratification

Invasive mussels filtering enormous volumes of water can increase water clarity, which paradoxically allows sunlight penetration to fuel algal blooms in new areas and alters the temperature stratification critical for native fish spawning cycles.
