Crushed Shells Mixed Into Sand Shielded Baby Clams From Acidified Water’s Genetic Stress in UC Davis Study
Nature World News | 10.11.2026 17:01Mixing crushed shells into sand lowered the acidity of the water around young clams and largely erased the genetic stress signal that acidified seawater triggers, according to a University of California, Davis study published Oct. 29 in Biogeosciences. The low-tech technique, known as adding shell hash, has long been used by Indigenous communities to keep clam beds healthy.
