Oyster Shells Reborn as Marine Nurseries | Los Angeles News
Description
In Southern California, a clever eco-hack is reviving native oysters: the Shell Strings program turns restaurant waste into underwater nurseries. Old oyster shells are cleaned, drilled, and strung to create floating habitats where baby oysters thrive. Started in Long Beach and now expanding across Orange County, the initiative has collected over 33,000 pounds of shells and distributed more than 1,100 strings. Each mature oyster filters 50 gallons of water daily and combats shoreline erosion—critical for the endangered Olympia oyster, whose population plummeted 90% in a century. Boat owners “foster” the strings by lifting them for sun exposure, turning environmental restoration into a community-driven, even competitive, effort.
