Jubilee is the name used locally for a natural phenomenon that occurs sporadically on the shores of Mobile Bay, a large body of water on Alabama's Gulf Coast. During a jubilee many species of crab and shrimp, as well as flounder, eels, and other demersal fish will leave deeper waters and swarm—in large numbers and very high density—in a specific, shallower coastal area of the bay. A jubilee is a celebrated event in Mobile Bay, and it attracts large crowds, many drawn by the promise of abundant and easy-to-catch seafood.
Although similar events have been reported in other bodies of water, Mobile Bay is the only place where the regular appearance of this phenomenon has been documented.
The Mobile Bay jubilee typically takes place at least annually, and sometimes several times per year; years without a jubilee have been recorded, but they are exceedingly rare. Many accounts of the jubilee exist, the oldest dating back to the 1860s.
The size, scope, and duration of the jubilee can vary greatly. Sometimes a 15-mile (24 km) stretch of coast representing most of the eastern shore can be affected, and at other times the extent can be limited to as little as 500 feet (150 m) of coastline. Most jubilees happen in the pre-dawn hours.
