The structure that oyster reefs create provide crevices that fish and crabs use to hide from predators. Oyster reefs are also a great place for smaller forage species to live. Many of the species that spend time around oyster reefs are recreationally and commercially valuable

A single oyster can filter up to 50 gallons of water per day. The clearer, cleaner water can support plentiful underwater grasses, which—like the oyster reef—create a stable bottom and a safe, nurturing habitat for juvenile crabs, scallops, and fish.

Oyster cultivation and harvest provide significant economic value to regional coastal communities. Farmed oysters, clams, and mussels account for about two-thirds of total U.S. marine aquaculture production.
