How to Restore Aquatic Habitat to Increase Fish Populations

Restoring California fish habitat is crucial to maintain native fish species as anadromous and other native fish populations decline in California rivers and streams. Drought conditions have exacerbated competition for dwindling water resources, increased aquatic habitat degradation, and contributed to invasions of non-native fish species.

Fish and other aquatic species require specific habitat for all life stages. Where the drought and other factors have wrought havoc, these aquatic habitats must be restored and enhanced to maintain/grow existing and historical aquatic communities. Additionally, restoring/enhancing river and stream habitats or native species will help them compete with non-native species, which exploit degraded habitat conditions and can quickly out-compete native populations
