And speaking of fishing and the WBTS--

"At the time of the Civil War, Union troops took over nearby Ship Island and carried out a blockade of the gulf. Citizens protected the city from invasion by the Yankees through the threatening appearance of fake cannons, which were really only logs planted in the sand. Mullet fish, called "Biloxi bacon," saved the local populace from starvation in the war years. The first fish cannery opened in 1881, and the city's seafood industry quickly developed. By 1900 Biloxi was termed the "seafood capital of the world." Polish, Austrian, and Acadian French soon came to the city to work in the industry, adding their own cultural influences. Tourism flourished and more hotels were built to accommodate the visitors, many of them from the Midwest, who came to escape the harsh northern winters."
