The Maireener Shell, Phasianotrochus Irisodontes, found only in the Southern seas of Australia and used by Aboriginal women for thousands of years, it is great cultural significance. Traditionally the shell was used as ornament, with strings broken apart in mourning. They were also used in trade for flint and ochres. The tradition of stringing shells continues in Tasmania today, with necklaces represented in most major museums and public galleries. They are valuable heritage items. See Lola Greenos work at Ian Potter Museum, Museum of Tasmania and the Powerhouse Sydney.

The Maireener shell is only found in limited locations, of the twelve recorded locations in Victoria three are to be found in the proposed dredge areas.

Phasianotrochus is a herbivore and grazer. They feed and live on the seagrasses Amphibolus and Posidonia. They are found at the low tide mark to a depth of five metres. At breeding time in summer they cover themselves in soft corals and migrate to deeper water to a depth of ten metres where they lay their eggs, which float for one or two days before anchoring themselves. They then migrate back in April. When they are found, they are found in abundance. They are an important source of food for Parrot fish and they live for one year.

Local produce is well represented at the supermarkets in both Lady Barron and Whitemark. Muttonbirds and fresh fish are available from Flinders Island Meats. Try the local ‘Fish of the Day’ in the Shearwater Restaurant at the Furneaux Tavern or sample the local wallaby at the Interstate Hotel. Dining out, it is recommended to book evening meals in advance. Eating in or wishing to dine on the beach, take away meals are available just ask.
