• Seawilding: Native Oyster Restoration "​Loch Craignish once supported a large population of native oysters but owing to human predation all but a few have gone. Native oysters are “ecosystem engineers”, filtering and cleaning water, sequestering carbon and contributing substantially to inshore biodiversity by creating reefs that become fish spawning grounds and nurseries.
  
  In 2020, Seawilding secured a National Lottery Heritage Fund grant for a five-year project to grow up to 1 million juvenile native oysters in Loch Craignish to restore the natural beds."

• Alamitos Bay Oyster Restoration Project "A 60 square meter oyster bed was created in Alamitos Bay using volunteers from the community. The public participated in the project through “oyster gardening” where community members  hung strings of oyster shell off of private or public docks around Alamitos Bay where the oyster strings  collected native oyster recruits.
  
  Scientific monitoring activities have been ongoing since the bed was constructed.  Densities of native oysters on the restored bed during the most recent sampling period were 65-103 times the average reference location density."

  Shells are picked up from local restaurants and transported to Port of Corpus Christi property where they are quarantined. The program has collected 3 million pounds of shell to date! The shell is then moved from the stockpile location to various sites for restoration efforts conducted by HRI. Over 45 acres of oyster reef habitat has been restored throughout the Mission-Aransas Estuary in Copano, Aransas, and St. Charles Bays. Each spring, volunteers from various groups participate in shell-bagging events to create the building blocks of reefs in St. Charles Bay, adjacent to Goose Island State Park. Thanks to over 2,000 volunteers to date, over 2 million pounds of shell have been placed in the bay to create new oyster reef habitat."

The shells are aged in local storage facilities for nearly a year and then placed in seeding tanks. The spat (baby oysters) attach themselves to the shells, which are then returned to the bay. Each shell might contain as many as 10 to 15 spat."
