Fish in the cascade

Fish in the cascade refers to fish living or moving through a cascade, which is a series of small waterfalls or rapids in a river or stream. Cascades present both challenges and opportunities for fish. They may navigate these natural barriers during migration, such as spawning runs or movements to different habitats. Some species, like salmon, are known for their ability to leap or jump up cascades during their upstream migrations. Additionally, cascades create unique habitats with varying flow rates and oxygen levels, which can support diverse aquatic life. Overall, fish in the cascade exemplify the adaptability and resilience of aquatic species in dynamic river environments.
