In effort to expand American fish farming, New Hampshire marine biologist joins congressional push

September 3, 2025 — Mike Coogan has been doing aquaculture, or fish farming, formally for over a decade. Informally — through at-home hobby fish tanks and aquariums — he’s been doing it much longer.

Now, he’s joined a legislative effort to streamline the regulatory process for aquaculture to help create a U.S. industry.

Coogan is a researcher at the University of New Hampshire, where he works on the school’s AquaFort, a pilot project where researchers are growing steelhead trout in the mouth of the Piscataqua River near New Castle.

“We have a tiny, tiny coastline, just 18 miles,” he said of the Granite State. “But we do a lot of interesting work, and have been sort of leaders in offshore aquaculture or open ocean aquaculture for the last 25 and change years.”

The fish farm uses a method called multitrophic aquaculture, which means they grow different species together, in small 20-by-20-foot underwater cages with 15-foot nets, Coogan said. They line the perimeter of the farm with sugar kelp and blue mussels to create “a biological curtain” to absorb nutrients and prevent disease. UNH is the only university growing fish in the ocean, he said.

That fish farm and others like it are far from a large-scale industry though. Aquaculture produces only 7% of domestic seafood in the U.S., according to the National Oceanic and Atmospheric Administration. Roughly 70% to 85% of seafood in the U.S. is imported, and it’s estimated half of that comes from aquaculture, per the NOAA. Aquaculture in the U.S. largely consists of catfish farms across the South. In New England, oysters and other shellfish are farmed. Coogan said the New Hampshire oyster farms are limited, with only a little over a dozen operating in Great Bay and Little Bay near Portsmouth and estuaries near Hampton.

FLORIDA: Is seaweed aquaculture the next big crop for Florida?

August 28, 2025 — Florida’s coastline may one day host more than oysters, clams, fish and shrimp. Researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and Florida Sea Grant are asking whether seaweed could be the state’s next big sustainable crop.

The effort, launched last year with a $250,000 grant from NOAA’s National Sea Grant Aquaculture Program, brings together scientists, industry partners and Extension agents to answer whether seaweed is a good fit for Florida. The findings could pave the way for a thriving seaweed farming industry much like it serves as a high-value crop in regions in Europe and the Americas.

Led by Ashley Smyth, an associate professor of soil, water and ecosystem sciences at the UF/IFAS Tropical Research and Education Center, the project team shared updates recently that sparked strong interest from researchers, aquaculture professionals and entrepreneurs in exploring the feasibility and economic potential of seaweed farming in Florida.

“Seaweed aquaculture has tripled over the past two decades — with Asia producing nearly all the supply — and it’s one of the fastest-growing commodity sectors globally,” said Angela Collins, Florida Sea Grant assistant Extension scientist specializing in marine fisheries and shellfish aquaculture at the UF/IFAS Tropical Aquaculture Lab and a co-principal investigator on the project.

Smyth explained that the research focuses on the potential and the

practical limits of cultivating seaweed in Florida’s warm waters.

“Seaweed acts like a sponge, pulling excess nitrogen out of the water,” she said. “If harvested, it removes that nitrogen completely, which means it could serve as both a product for growers and a tool for improving water quality.”

Florida’s unique environment presents opportunities and unknowns.

With Wild Fish Stocks Dwindling, Congress Considers Backing Aquaculture

August 22, 2025 — Advocates for increasing Hawaiʻi’s aquaculture production are buoyed by the introduction of federal legislation that could supercharge the almost $2 billion national fish farming industry, a sector many believe has been neglected by state authorities for too long.

The bipartisan bill, co-sponsored by Sen. Brian Schatz of Hawaiʻi, intends to streamline permitting, build the aquaculture workforce, facilitate research and development, and eventually pave the way for offshore, commercial-level demonstration facilities across federal waters.

The draft Marine Aquaculture Research for America Act, or MARA Act, aims to boost production throughout the country to lessen the nation’s reliance on imported products, which account for 75% to 90% of its seafood — and 63% in Hawaiʻi. The legislation is a streamlined revival of a previously failed bill, although aquaculture industry leaders say it may now be primed for success.

MAINE: The future is now: Salmon aquaculture embraces precision farming

August 21, 2025 — From afar, the series of 100-meter rings that constitute an Atlantic salmon farm site in the Gulf of Maine appear unchanged since the transition from steel cages to high-density polyethylene pens in the late 1990s and early 2000s. But that couldn’t be further from the truth.

Atlantic salmon aquaculture has been practiced in Maine since the late 1970s and early 1980s, with the first commercial lease being issued by the Maine Department of Marine Resources for a farm site in Cobscook Bay near Eastport in 1982. The industry has evolved and modernized tremendously since then, with the adoption of precision farming defining the last 20 years or so.

So what is precision farming? Also known as precision agriculture, precision farming refers to the use of advanced technologies and data analysis to optimize farming practices. Farmers who embrace precision farming, in theory, increase efficiency and productivity and minimize environmental impact.

For aquatic farmers, that translates to more precise and scalable ways to feed fish and to monitor fish health and growth, ocean conditions and water quality.

Cooke USA has been farming Atlantic salmon in Maine since 2004, celebrating 20 years of aquaculture operations in the state last year. Today, Cooke USA’s operations consist of marine farm sites in Downeast Maine, a processing plant in Machiasport, and three land-based freshwater hatcheries in both the eastern and western parts of Maine. Its fresh farmed Atlantic salmon is sold at supermarkets and restaurants throughout New England and the United States.

It was around the early 2000s that the company, and the industry by and large, began embracing precision farming. It’s what a passerby on a boat or an onlooker from the shore can’t see that’s revolutionizing Atlantic salmon aquaculture in Maine and globally — hardware such as underwater cameras and sensors, which have been used for years, and the AI-enable software behind the hardware.

ALASKA: Alaskan research outlines methods to deter Pacific herring from spawning on kelp farms

August 19, 2025 — Kelp aquaculture operations are rapidly expanding in Alaska and coming into increasingly greater contact with wild marine species.

In an attempt to limit some of the interactions between Alaska’s aquaculture operations and wild species, researchers have outlined strategies to prevent Pacific herring from spawning and laying eggs on kelp farmed at aquaculture farms along the state’s coast.

New York judge sides with Oyster Bay in aquaculture lease renewal decision

August 13, 2025 — A court in the U.S. state of New York has ruled in favor of the Town of Oyster Bay on Long Island, New York, dismissing a long-term aquaculture leaseholder’s complaint that the town didn’t renew its lease for 1,800 acres of shellfish harvesting area.

“A reading of the town code makes it clear that the town was not required to renew the lease,” Nassau County Supreme Court Judge Gregg Roth said in his decision dismissing the former leaseholder’s claims.

New tariffs could boost Gulf Coast seafood industry, as lawmakers push for sustainable aquaculture

August 8, 2025 — New tariffs ranging from 15% to 20% take effect this week on a wide range of imported goods, including fruits, vegetables, meat, dairy, and fish.

While shoppers may feel the pinch at the checkout, some in the U.S. seafood industry see an opportunity.

Nearly 85% of the seafood consumed in the United States is imported, according to Galveston fisherman, Scott Hickman. Major seafood suppliers including Vietnam and Indonesia both now facing new tariffs of up to 20%. The changes, part of the latest round of President Donald Trump’s trade war, are prompting renewed focus on sourcing food domestically.

For longtime Galveston fisherman Hickman, this is a welcome shift.

“America’s become addicted to cheap seafood that’s raised in ways they wouldn’t approve,” Hickman said. “Most Americans, I think, would rather spend a little bit more for the shrimp po’ boy or the crab fingers if they know it’s American-produced.”

Hickam says tariffs level the playing field for fishermen. He’s also pointing to new legislation in Congress looking to expand seafood production in the United States.

Aquaculture can help produce more US seafood

August 8, 2025 — Demand for sustainable protein is on the rise, but the U.S. already harvests the sustainable limit of wild-caught seafood. Our solution is to import up to 85 percent of our seafood — half of that sourced from fish farms in other countries.

So why aren’t we instead eating seafood from sustainable American fish farms in our own deep ocean waters?

Members of Congress have proposed a solution to tackle the chief obstacle to American open ocean aquaculture. The bipartisan Marine Aquaculture Research for America Act of 2025, introduced by Sens. Brian Schatz (D-Hawaii) and Roger Wicker (R-Miss.), would help create a pathway for open ocean aquaculture in America by establishing an assessment program to evaluate commercial-scale demonstration projects in federal waters.

Open ocean aquaculture is supported by the nation’s most influential environmental groups, but to date, not a single commercial-scale finfish farm operates in U.S. federal waters. Recently, a small, single-pen demonstration farm proposed off the coast of Florida was the first offshore project to receive a permit after being mired in the permitting process for more than seven years.

The project, which has federal grant funding from the National Oceanic and Atmospheric Administration and a permit from the Environmental Protection Agency, still faces more regulatory hurdles ahead before it is fully approved to enter the water.
