October 3, 2025 — The U.S. maritime economy is growing faster than the economy as a whole, supporting over 2.6 million jobs and contributing $511 billion to the nation’s GDP.
From lobster docks in Maine to oyster farms in Florida, kelp farms and commercial fisheries on the West Coast to maritime training in Alaska, charter fishing in the Gulf, and inland shipping in the Great Lakes, America’s coastal and freshwater industries are fueling economic growth, feeding families, and sustaining communities.
At the heart of that growth is Sea Grant, a trusted federal program linking science, communities, and industry across every coastal and Great Lakes state. According to the most recent federal data, the marine economy grew by 5.9 percent in GDP, outpacing national GDP growth, and Sea Grant plays a critical role in sustaining and accelerating that momentum.
Modeled after the Land Grant college system that helped transform American agriculture, the Sea Grant college program has spent more than 50 years doing the same for the nation’s marine and freshwater economies, combining applied research, hands-on education, and direct investments in communities and businesses to promote sustainable growth.
That model works. It works for the charter boat captain who needs up-to-date science on fish stocks, reef health, and ocean conditions. It works for the shellfish farmer navigating complex permitting processes, building a skilled workforce, and developing business plans to stay competitive. It works for the lobsterman who relies on data about juvenile lobsters entering the fishery to make informed decisions about their gear, boat, and future, because without that data, they’d be navigating blind. It works for the seafood processor hiring the next generation of workers, and for the harbor manager planning infrastructure upgrades to withstand future storms. It works for the grocery shopper a thousand miles from the coast looking for fresh, healthy seafood, and for the inland communities whose economies depend on waterborne trade and shipping. It works for families, for small businesses, for regional economies, and ultimately, for the nation.
