## Resource

Salmon need silence to survive—new research reveals hatchery-raised fish exposed to constant noise are nearly half as likely to return to spawn, threatening recovery efforts across the Pacific Northwest. Scientists at Washington State University found that even subtle sound differences in early life can drastically impact survival, suggesting quiet zones or sound-dampening tech could be key to boosting wild salmon populations.
