Oysters are highly nutritious and possess medicinal value. According to the Food and Agriculture Organization ( FAO, 2018), global oyster production stands at around 6.1 million tons per year, and worldwide, oyster exports increased threefold from 1997 to 2017. Oyster aquaculture has been practiced for over 2,000 years ( Campbell and Hall, 2018). Oyster is an important and extensively farmed marine resource with high commercial value ( Cheng et al., 2021 Hao et al., 2021). This review clearly shows that oysters have great potential for functional food production and that various compounds therein can have pharmaceutical applications. Bioactive peptides and proteins obtained from the whole, mantle, and gill tissues of oysters exhibit antioxidant, antimicrobial, antihypertensive, anticancer, antifatigue, anticoagulant, and anti-wrinkle effects, as well as enhance osteoblast differentiation.

The various biological compounds present in an oyster shell, and their chemical constituents, have applications in the food, pharmaceutical, and medical industries. The present review summarizes the biological applications and bioactive compounds from oyster shells, whole tissue, gill tissue, and mantle tissue. As well as being highly nutritious, oysters are a low-calorie, low-cholesterol source of protein and an exceptional source of zinc, which strengthens the immune system and a rich source of bioactive compounds, which comprise various biological activities. Oysters are saltwater bivalves with high nutritional and medicinal value that are consumed widely around the world. 3Institute of Fisheries Sciences, Pukyong National University, Busan, South Korea.
