The fish species famous for its spawning runs in Pacific rivers is Salmon.

Salmon are iconic fish known for their remarkable spawning behavior, where they migrate from the ocean back to the freshwater rivers where they were born. This incredible journey often involves traveling hundreds of miles upstream, navigating obstacles like waterfalls and dams. The most notable species include Chinook, Coho, and Sockeye salmon, each with unique life cycles and spawning patterns. This annual migration is not only a critical part of the salmon's life cycle but also a vital ecological event that supports various wildlife, including bears, eagles, and humans. Salmon are culturally and economically significant, playing an essential role in the diets and traditions of many Pacific Coast communities. Conservation efforts are ongoing to address challenges such as habitat loss, overfishing, and climate change, which threaten their populations and spawning runs.
