There is no consensus on the origin of the name "Fanny Bay" and none of the various explanations — comical, romantic, local or historical — can be considered without skepticism. The name first appeared on British Columbia maps in 1913 and was officially adopted by the government in 1923. This adoption was based on British Admiralty charts of the 1860s, taken from surveys by Royal Navy Captain G.H. Richards. However, if Capt. Richards knew who "Fanny" was, he did not record the information. Geographer A.B. McNeill wrote in his book Origin of Station Names, Esquimalt and Nanaimo Division that "...Fanny Bay was named after a sea captain who lived in this vicinity". Alas, like Capt. Richards, McNeill provides no dates or any other supporting information. A popular and persistent local theory holds that Fanny Bay was named by Captain George Vancouver in 1792. However, Capt. Vancouver's nautical charts and journals only describe the east side of the nearest body of water, the Strait of Georgia. He had nothing more than a rough outline of the eastern shore of Vancouver Island between Nanaimo and Comox, and his charts omitted several nearby islands and other features. Therefore, it seems highly unlikely that Capt. Vancouver would have been able to proffer this name.
Shellfish
Fanny Bay is well known as a source of farmedshellfish, specifically Pacific oysters, manila clams, savoury clams and mussels, for both domestic and global markets. Oysters were introduced to the area as early as 1912 or 1913, with further seedings around 1925. As a result of the lack of Pacific oysters from Japan during World War II, further seeding occurred in 1942. The first major oyster and clam seeding in Baynes Sound at Fanny Bay occurred about 1947, by Joseph McLellan, a pioneer in oyster aquaculture. McLellan imported his first batch of oyster seed from Japan and seeded the beach areas around Fanny Bay - Mud Bay, Ship Point, Buckley Bay and Denman Island. His work started what is now a primary industry in the South Coast of British Columbia, Canada, employing over one hundred people and contributing significantly to the economy of the Baynes Sound region. McLellan's descendants still own and operate the oyster and clam farm located in Fanny Bay, Mac's Oysters Ltd. A fourth-generation family shellfish farm, Mac's Oysters is the only shellfish processor situated in Fanny Bay, though there is another company by that name, located in Union Bay approximately 11 km to the north. Mac's Oysters is a significant player in the Canadian farmed shellfish industry, processing approximately 34% of all of British Columbia's farmed oysters and clams from this area. Within food circles Fanny Bay is synonymous with oysters. Manila clam seed was inadvertently included in Joseph McLellan's initial seed shipments from Japan. The manila clam is as important as oysters to British Columbia's shellfish economy.
