This Alabama bay shares a rare ocean event with only one other place on Earth

Mobile Bay’s 150-Year Jubilee Harvesting Tradition

For over 150 years, folks along Mobile Bay’s Eastern Shore have jumped from their beds at strange hours for a rare gift from the sea. The first written account came in 1867, though locals knew about it long before.

They called it a “jubilee” by 1912 – when fish and crabs pile up in shallow water, gasping for oxygen.

Captain Frank Phillips told scientists in 1960 he’d seen these events for six decades, just as his father had before him.

When conditions are right, neighbors still ring bells and make calls, rushing to shore with nets and tubs. The Mobile Bay jubilee remains one of just two places worldwide where this natural phenomenon occurs.

Fishermen First Spotted the Strange Phenomenon in 1867

The Mobile Daily Register printed the first story about a jubilee on July 17, 1867. The article told readers about fish crowding the eastern shore of Mobile Bay in huge numbers.

People living nearby knew about these odd fish gatherings long before. Native Americans probably saw jubilees happen centuries before European settlers came.

Locals noticed fish, crabs, and other sea creatures suddenly showing up in shallow water but couldn’t figure out why. This 1867 newspaper story started the written record of this natural event.

The Word “Jubilee” Stuck After a Fisherman Used It in 1912

A local fisherman talking to the Mobile Daily Register on July 29, 1912, called the strange event a “jubilee. ” He told the paper about hundreds of crabs and fish covering the beach at Point Clear.

The newspaper printed what he said, and the name caught on quickly. The word fit well because jubilee means a time of celebration.

Families who rushed to the shore to gather the sudden bounty felt exactly that kind of happiness. People along the Eastern Shore still use this name today.

Oxygen Gets Scarce and Forces Sea Creatures to Shore

Scientists found that jubilees happen when dead plants and animals rot on the bay floor. This process uses up oxygen in the deeper water during hot summer months.

Flounder, crabs, and shrimp can’t breathe in the low-oxygen water, so they swim toward the shore where oxygen levels stay higher. This natural event happens in only two places worldwide: Mobile Bay and Tokyo Bay.

Early residents didn’t know about oxygen levels, but they learned to spot the signs before a jubilee.

Families Passed Down Jubilee Knowledge Through Generations

Captain Frank Phillips told researchers in 1960 that he watched jubilees happen for 60 years without any changes in how often they occurred. He said his father saw the same events throughout his life before him.

Grandparents taught grandchildren how to read the bay’s signals.

They showed kids what time of year to watch for jubilees and which beaches usually got the most fish. People who grew up along the Eastern Shore learned to keep an eye on the water during summer nights.

A Scientist Named Loesch Studied Jubilees for Ten Years

Marine biologist Harold Loesch wanted to understand jubilees better, so he watched the bay from 1946 to 1956. During his ten-year study, he counted 37 separate jubilee events.

Loesch noticed jubilees never happened outside summer months. They always occurred between June and September, with August having the most.

His research showed that jubilees mostly happened along a specific stretch of shoreline from Point Clear to Daphne.

Five Special Conditions Need to Line Up for a Jubilee

Loesch published his research in the journal Ecology in 1960.

His paper listed five key conditions needed for a jubilee to happen: summer months, early morning hours before dawn, winds blowing from the east, a tide coming in, and salty water pushing into the bay.

When these five things happen together, the chances of a jubilee increase greatly. Even with all this knowledge, Loesch admitted jubilees remained somewhat hard to predict.

Another Researcher Named May Backed Up the Findings

Edwin B. May did more research and published his results in 1973.

His study checked Loesch’s work and found the same five conditions needed for jubilees to occur. May collected more data about water temperature, oxygen levels, and sea life behavior during jubilee events.

Despite all this research, scientists still cannot predict exactly when a jubilee will happen, making each one a surprise.

Neighbors Created Their Own Warning Systems

Communities along the Eastern Shore came up with clever ways to spread news when a jubilee started. People rang bells, knocked on doors, and called neighbors when they spotted signs of fish moving to shallow water.

The alerts often came in the middle of the night or very early morning. Families jumped out of bed, grabbed their gear, and hurried to the beach.

These warning networks worked even before telephones became common in rural areas.

People Filled Washtubs and Truck Beds With Seafood

Author Archie Carr wrote about the huge amount of seafood people caught during good jubilees. Folks scooped up enough shrimp to fill multiple washtubs in just minutes.

A person with a gig could spear hundreds of flounder in a single morning as the fish lay still in shallow water. Crabs crawled onto the beach in such numbers that people filled the beds of pickup trucks.

People canned, froze, and shared their catch with neighbors.

Beach Parties Form When Conditions Look Right

Modern families still watch for signs that a jubilee might happen.

When the water looks right and the wind blows from the east on a summer night, people gather at the waterfront just in case. They bring flashlights and lanterns to shine into the water, looking for movement.

These gatherings turn into impromptu beach parties as neighbors wait together, talking and watching the bay. Children play while adults keep an eye on the water.

Only Two Places on Earth Experience This Natural Wonder

The jubilee tradition continues after more than 150 years of written history.

Each new generation learns about jubilees from parents and grandparents who experienced them firsthand. The excitement feels the same now as it did when the first newspaper article mentioned the phenomenon in 1867.

What makes Mobile Bay jubilees even more special is their rarity worldwide. Only Tokyo Bay in Japan experiences similar events.

This makes the Eastern Shore of Mobile Bay one of just two places on Earth where people can witness this strange and wonderful natural phenomenon.

Visiting Fairhope, Alabama

You can experience the Mobile Bay jubilee tradition at Fairhope Municipal Pier on the Eastern Shore. These rare events happen unpredictably from June through September, usually in August before sunrise.

Join “Jubilee Watch Baldwin County” on Facebook for real-time alerts when jubilees occur.

You can harvest flounder, crabs, and shrimp with dipnets or bare hands without a fishing license, but size limits still apply. The Taste of Fairhope Food Tour shares jubilee history stories Fridays and Saturdays at 2pm.
