Ark clams are edible mollusks that have been consumed since pre-historic times and are still consumed today. Numerous recipes for ark clams have been published. Recreational foragers should follow seafood safety guidelines and shellfish harvesting restrictions, and should be aware of any harmful algal blooms that may contaminate shellfish with biotoxins. Shellfish collected in urban areas should not be eaten raw.
Tegillarca granosa was used as a food by Indigenous peoples living on the northern Australian coastline through at least the past ~4500 years, with extensive evidence preserved in the form of shell mound sites.5 Large ark clams, such as Arca zebra, are commonly used as bait, as well as food, throughout the Caribbean. In Japan, red Ark clams, called Akagai, are used in sushi or sashimi.6 Some ark clams species, such as the blood cockle (Anadara granosa, a.k.a. Tegillarca granosa) are raised in aquaculture, e.g. in the estuaries of China's Fujian coast.7 In the U.S. limited quantities of wild ark clams have been harvested in North Carolina and Virginia for ethnic markets and aquaculture has been explored. 8
In the south Pacific region, Ark clams are still gathered by indigenous people as an important subsistence food. Ark clams are harvested, mostly by women, by gleaning intertidal zones.9 To maintain the Ark Clam fishery, several communities in Fiji are imposing a minimum size limit of 3 cm, closures during spawning periods, and establishing "no-take" areas.10
