This makes winkles the sixth most important shellfish harvested in Scotland in terms of tonnage, and seventh most important in terms of value. Hereafter, the winkles are commonly packed in smaller quantities before being distributed to customers. Ongrowing has been investigated as a potential way of increasing commercial value, but no documented pilot facilities have been established. [3] The shell lacks an umbilicus.

The true nature of the supply chain is usually more complex and opaque, with the potential for records of harvesting areas and date of catch to be falsified. The first is about the freshwater mollusc group, Cremnoconchus, commonly called Cliff Shell or Freshwater Periwinkle, which has relatives in the marine environment; all known species are found only in Karnataka and Maharashtra.

Female specimens have been observed to be ripe from February until end of May, when most are spawning. Raising the common periwinkle has not been a focus due to its abundance in nature and relatively low price; however, there are potential benefits from aquaculture of this species, including a more controlled environment, easier harvesting, less damages from predators, as well as saving the natural population from commercial harvesting. A. Kitching. [12] This species is also found on the west coast of the United States, from Washington to California.
