A small fishing fleet of seven is protected by a breakwater built in 1908. Mullet used to be an important catch in the bay with the fishery beginning at the end of January and continued towards the end of April. Sennen Cove was the most important seine fishery in Cornwall and, in Edwardian times, large schools were still entering the bay with as many as 12,000 caught at one time. Seining continued into the 20th century with 1200 stone caught on 3 March 1977.
