Aquaculture Opportunity Areas bolster America-First seafood production

September 19, 2025 — The following was released by NOAA Fisheries:

As part of NOAA’s commitment to prioritizing American seafood competitiveness, the agency has identified 13 Aquaculture Opportunity Areas totaling more than 21,000 acres in U.S. federal waters of the Gulf of America and off the coast of Southern California. These areas will strengthen the nation’s seafood industry, reduce reliance on foreign imports, and create high-quality American jobs.

Today’s release of two final programmatic environmental impact statements for the Gulf of America and Southern California identifies prime locations that may be suitable for developing multiple commercial aquaculture projects, fulfilling President Trump’s 2020 Executive Order “Promoting American Seafood Competitiveness and Economic Growth” and supporting the 2025 Executive Order “Restoring American Seafood Competitiveness”. These orders champion a robust, America-first seafood industry that puts U.S. workers and consumers first.

Each year, Americans eat roughly $15 billion in seafood farmed and imported from foreign countries, where labor and environmental standards often fall short of America’s rigorous standards. By expanding domestic aquaculture to complement wild-harvest fisheries, NOAA is driving an America-first approach that creates jobs, supports coastal communities, and ensures  high-quality, homegrown seafood for American families.

“The U.S. leads the world in aquaculture science and technology, yet we rank 20th globally in marine aquaculture production,” said Eugenio Piñeiro Soler, acting assistant secretary of commerce for oceans and atmosphere and NOAA Fisheries assistant administrator. “By growing our domestic aquaculture industry, we will strengthen American health, create good-paying jobs, and drive sustainable, long-term economic growth for our nation.”

The final documents released today are grounded in 19 scientific support products and incorporate robust public input, building on draft documents released last year. These efforts reflect NOAA’s commitment to transparency and American-driven decision-making.

In Southern California, NOAA experts identified 10 prime locations for potential aquaculture development –  eight in the Santa Barbara Channel and two in Santa Monica Bay – ranging from 500 to 2,000 acres, totaling 16,500 acres. NOAA found these areas may be suitable for seaweed, shellfish, and finfish aquaculture.

In the Gulf of America, three locations off the coast of Texas were identified, each ranging in size from 500 to 2,000 acres, totaling 4,500 acres. NOAA found these areas may be suitable for seaweed, shellfish, and finfish aquaculture. NOAA is also investing in baseline environmental surveys in the Gulf to provide valuable data to prospective farm applicants.

The Aquaculture Opportunity Areas will be finalized with two decision documents following this announcement. The selected areas are just the beginning of unlocking the vast potential for aquaculture in U.S. waters, paving the way for more jobs, thriving coastal economies, and an increased abundance of high-quality American-raised seafood on Americans’ plates.

More information on the final PEISs for Southern California and the Gulf of America is available on the NOAA Fisheries website. 

Genomics Help Uncover Mysteries of Atlantic Bluefin Tuna

September 19, 2025 — The Slope Sea may hold a key to better understanding Atlantic bluefin tuna. 

This summer, scientists journeyed to the Slope Sea on two exploratory surveys to examine how Atlantic bluefin tuna use this area for reproduction (also known as spawning). The first survey was a cooperative longline survey to look for spawning fish. The second survey followed closely on their heels to look for the results of that spawning—larval, or baby, bluefin tuna.

The objective was to document the potential contributions of spawning between the Slope Sea and other spawning areas like the Gulf of America. Next they will analyze DNA from both larval and adult bluefin tuna to estimate the population (stock) size. Atlantic bluefin tuna has been managed as having two primary stocks—one that spawns in the Mediterranean Sea (the eastern) and the other in the Gulf of America (the western). Recent research suggested the Slope Sea could be a major spawning ground comparable to the Gulf of America. Genetic research has shown the two stocks are interconnected. This year’s survey aims to clarify remaining uncertainties about bluefin tuna stock structure and spawning dynamics.

New Test Measures Toxin from Tires in Marine Life, Helping Understand Risk to Marine Species and Ecosystems

September 18, 2025 — Scientists at NOAA’s Northwest Fisheries Science Center helped pioneer the study of an automobile tire toxin found to kill salmon when it runs off highways in stormwater and into streams. Now they have found a way to measure the toxin, 6PPD-quinone, directly in marine life, including fish, shellfish and marine mammals.

The new method can help scientists better understand how the toxin affects different species, and how it reaches and moves through marine ecosystems. It can help assess effects on more species in less time. That may, in turn, help managers find ways to reduce the risk it poses to salmon and other species. This will allow the fish to continue to support economically important tribal, commercial, and sport fisheries, bringing economic and environmental value to the region.

“Without being able to measure it, we won’t be able to answer questions about its impacts on species,” said Li-Jung Kuo, who led research by the Science Center’s Environmental Chemistry Program to develop the new method.“We need to have a better understanding of 6PPD-Q distribution in the environment, including aquatic species. The capability to directly measure the 6PPD-Q body burden in aquatic species is a step forward, as it is essential for exposure assessment.”

The identification of and research on 6PPD-quinone illustrates how hidden threats can lurk in our everyday lives. From the water we drink to the rivers and oceans that sustain countless species, our lives are intricately connected to aquatic environments. This vital connection means that our daily actions, both big and small, can have a profound impact on water quality and the health of its inhabitants. One such emerging concern stems from something as common as vehicle tires, specifically 6PPD-quinone, which is proving to be a silent killer for some species.

NOAA Fisheries Partners with Smithsonian to Archive Marine Specimens for Genetic Research

September 17, 2025 — The Pacific Islands Fisheries Science Center recently archived more than 700 fish and squid specimens at the Smithsonian Institution’s National Museum of Natural History. Science Center researchers collected the specimens during research surveys. This collaborative effort will support genetic research efforts for generations and help scientists better understand and sustainably manage marine species in the Pacific.

Collaboration

In June 2025, Dr. Matt Girard, a zoologist and visiting scientist from the Smithsonian, collaborated with NOAA’s Dr. Jonathan Whitney and research scientists from the Pacific Islands Fisheries Science Center in Honolulu. The center houses a vast collection of marine specimens, including fish and cephalopods, collected over decades through research surveys and NOAA’s Observer Program. To support long-term preservation and enhance genetic reference libraries, the Smithsonian offered to take custody of select specimens from the collection.

Specimens Taken to the Smithsonian

The collection included:

NOAA Fisheries staff, interns, and volunteers carefully processed, preserved, and packaged the specimens. They then shipped them to the Smithsonian. Many have already been cataloged into the National Collections and will serve as the genetic standard for their species in our region.

Steep decline in landings show imports’ impact, US shrimpers say

September 16, 2025 — NOAA Fisheries landings data for 2024 show sharp declines in U.S. Gulf and South Atlantic catches. That trend is likely an indicator of the impact competition from inexpensive imported shrimp is having on the U.S. domestic market, according to the Southern Shrimp Alliance.

The U.S. landings “confirm the incredible damage caused to the U.S. shrimp industry by the massive influx of cheap, farmed shrimp imported into this country over the last four years,” the alliance said in its analysis issued Sept. 15.

NOAA’s figures show 158.9 million pounds of shrimp were landed in the Gulf and South Atlantic last year with a total value of $257.9 million. “This is by far the lowest amount of shrimp harvested in these regions since 1961,” according to the alliance.

The industry group’s paper includes graphics generated from annual landings totals.

Where the Copepods Are: Prey Data Can Improve Right Whale Models

September 16, 2025 — A new peer-reviewed study in Endangered Species Research finds that incorporating maps of copepod aggregations into North Atlantic right whale density models could improve those models’ predictions. The study used data on aggregations of three copepod species collected 2003–2017 from Cape Hatteras, North Carolina, to the Scotian Shelf in Canada. Scientists on the Northeast Fisheries Science Center’s Ecosystem Monitoring Survey collected that data.

Under the Marine Mammal Protection Act and the Endangered Species Act, NOAA Fisheries studies marine mammals, including endangered North Atlantic right whales. We find ways to reduce risks posed to them by human activities and environmental change to recover and protect species.

Modeling Right Whale Distribution Supports Proactive Management

There are approximately 370 North Atlantic right whales remaining, including only about 70 reproductively active females. Right whales feed on copepods, a type of zooplankton. They forage off the Northeast coast of the United States and Canada in the winter and spring when copepods are most abundant there. Their foraging grounds overlap with shipping, fishing, and other human activities. This puts them at risk of entanglement and vessel strikes, the two primary causes of right whale deaths. Changes in climate and oceanographic conditions are shifting the availability of copepods and thus the distribution of whales. Modeling right whale distribution allows for effective management to prevent human-caused whale deaths and injuries. Examples of this include Right Whale Slow Zones and Dynamic Management Areas.

Scientists predict the distribution of these whales using density surface models based on visual data collected from aerial and shipboard surveys, along with acoustic data. For this study, scientists used aerial and shipboard survey data, which included 5,196 individual whale sightings by seven institutions from 2003-2017.

NOAA Fisheries Announces Closure of Commercial Atlantic Mackerel Fishery

September 12, 2025 — The following was released by NOAA Fisheries:

NOAA Fisheries has projected that 80 percent of the Atlantic mackerel domestic annual harvest (DAH) has been harvested as of September 4, 2025. Therefore, effective 0001 hr local time on September 16, 2025, limited access mackerel vessels may not take and retain, possess, or land more than 10,000 lb of mackerel per trip at any time, and may only land mackerel once per calendar day, through 24:00 hr local time on December 31, 2025. Additionally, open access mackerel vessels may not take and retain, possess, or land more than 2,500 lb of mackerel per trip at any time, and may only land mackerel once per calendar day, through 24:00 hr local time on December 31, 2025.

Limited access vessels that enter port before 0001 hr local time on September 16, 2025, may land and sell more than 10,000 lb of mackerel from that trip, and open access vessels that enter port before 0001 hr local time on September 16, 2025, may land and sell more than 2,500 lb of mackerel from that trip, consistent with the applicable possession limits. The possession limits for the mackerel fishery will reset to the amounts outlined at §§ 648.26(a)(1)(i) and (ii) on January 1, 2026.

Supporting Fisheries Research and Restoration in Georgia’s Largest Watershed

September 9, 2025 — The Altamaha River Basin in Georgia drains more than 14,000 square miles—including rivers in Athens, Macon, and parts of southeast Atlanta—into the Atlantic Ocean. Fish species like American eel, shad, blueback herring, and sturgeon use the Ocmulgee and Oconee Rivers and other tributaries in the watershed as they migrate upstream. However, several barriers, including the Juliette and Sinclair Dams, limit access to upstream habitat these fish have historically used for spawning. These dams are also reducing the quality of habitat by converting natural, free-flowing rivers into artificial lakes and interrupting the downstream flow of sediment.

NOAA worked alongside state and federal resource agencies to develop a basin-wide plan to re-establish fish passage above human-made barriers. The plan also addressed restoring the quality and quantity of available spawning habitat. To inform strategic fish passage design and implementation of the plan, we funded two university-led studies in the basin.

U.S. champions sustainable tuna fisheries in Eastern Pacific, boosting American fishermen and conservation

September 9, 2025 — The following was released by the NOAA Fisheries:

The United States took a bold leadership role last week at the annual Inter-American Tropical Tuna Commission (IATTC) meeting, driving innovative measures to sustainably manage tuna fisheries in the Eastern Pacific Ocean. Under the guidance of NOAA’s Principal Deputy Assistant Secretary for International Fisheries, Andrew Lawler, the U.S. delegation prioritized American interests by enhancing conservation efforts, strengthening monitoring programs, and expanding opportunities for American fishermen.

The IATTC, comprising 21 member nations, convened to manage highly migratory fish stocks using the best available science and consensus-driven decisions. The U.S. spearheaded critical advancements in tropical tuna management, Fish Aggregating Device (FAD) recovery, and regulatory simplification, reinforcing America’s commitment to both environmental stewardship and economic prosperity for its fishing industry.

Bolstering Tropical Tuna Management

The United States led discussions on managing bigeye, yellowfin, and skipjack tuna and secured $1.8 million in funding for the Regional Tuna Tagging Program. This U.S.-backed initiative will enhance understanding of tuna distribution and stock health, ensuring sustainable harvests that support U.S. fishermen. The U.S. also championed the creation of the Integrated Port Sampling Program, merging traditional and enhanced monitoring efforts to deliver precise data on stock health and fleet impacts. By reducing closure days for purse seine vessels—after scientific confirmation of healthy tuna stocks—the U.S. fought to ensure greater access for American fishermen to these stocks without compromising sustainability.

Pioneering Fish Aggregating Device Recovery

FADs are critical to efficient fishing in the Eastern Pacific, but abandoned FADs can harm marine ecosystems. The American Tunaboat Association, showcasing U.S. leadership, spearheaded a multinational industry coalition that committed significant funding to FAD recovery programs. With strong U.S. support, the IATTC adopted an expanded resolution to streamline FAD retrieval, promote biodegradable materials, and deploy tracking devices, in an effort to protect marine environments while supporting fishing communities.

Additional Measures to Support American Interests

Furthermore, the United States drove the adoption of measures to reduce regulatory burdens, ensuring American fishermen greater operational efficiency. In addition to securing several adopted measures, the U.S. also supported the creation of a South Pacific Albacore Joint Working Group with the Western and Central Pacific Fisheries Commission, extending measures to protect silky sharks, and establishing a Dorado Working Group to assess stock health—initiatives that safeguard America’s long-term fishing interests while promoting global sustainability.

“America’s leadership at the IATTC demonstrates our commitment to sustainable fisheries that protect our oceans and empower our fishermen,” said Andrew Lawler. “These measures strengthen our economy, enhance conservation, and position the U.S. as a global leader in responsible fishery management.”

The United States remains dedicated to advancing science-based, America-first policies that ensure the prosperity of its fishing industry and the health of the Eastern Pacific’s marine ecosystems.
