The economic impact study comes six months after Ocean first reported that about one-third of seafood sold in the U.S. is mislabeled.
That two-year study of 1,200 seafood samples found that 33% were mislabeled according to U.S Food and Drug Administration guidelines.
The latest report sought to find out just how much consumers lost when they were sold cheap substitutes. According to the group, consumers who order an 8-ounce fillet of grouper in a restaurant, which sells on average for $27, but are instead given a tilapia fillet, worth $15, they lose $12.
“Swapping a lower cost fish for a higher value one is like ordering a filet mignon and getting a hamburger instead,” said Oceana senior scientist Margot Stiles. “If a consumer eats mislabeled fish even just once a week, they could be losing up to hundreds of dollars each year due to seafood fraud.”
Wednesday's report is based on a review of 300 menus from 12 different cities to help estimate retail prices, Oceana said.
Congress in March introduced legislation intended to minimize seafood fraud. Bills are currently sitting in committee in the House and Senate.
That legislation followed the February report, which highlighted just how complex the chain is from boat to retail stores and restaurants.
Oceana said that the most commonly mislabeled fish were snapper and tuna.
Of the samples labeled as snapper, 87% were mislabeled. More than 30 different species of fish were found to be substituted for snapper, but the most common were rockfish and tilapia.
(vasep.com.vn) Vietnam’s tuna exports reached USD 81 million in April 2026, down 6% compared to the same period in 2025. In the first four months of the year, export turnover totaled USD 289 million, down 4.8%. Although the overall export picture has yet to brighten significantly, market trends are becoming increasingly diversified rather than moving in a single direction.
(seafood.vasep.com.vn) Vietnam’s pangasius industry is undergoing strong restructuring starting from the broodstock and fingerling segment in order to improve productivity, quality, and export competitiveness. This is considered a critical foundation for the sustainable development of the industry amid rising production costs and increasingly stringent market requirements.
(seafood.vasep.com.vn) According to Vietnam Customs data, pangasius exports in April 2026 reached USD 206 million, up 18% compared to the same period in 2025 — marking another consecutive month of double-digit growth since the beginning of the year. Cumulative pangasius export turnover in the first four months of 2026 reached USD 720 million, up 17% year-on-year, reflecting the positive growth momentum of this key export product.
(seafood.vasep.com.vn) Vietnam’s shrimp exports in the first four months of 2026 maintained positive growth momentum, reaching approximately USD 1.5 billion, up 15% compared to the same period last year. However, behind this result lies diverging trends across markets, as the global shrimp industry continues to face pressure from inflation, high inventories, price competition, and increasing trade risks.
(seafood.vasep.com.vn) In Vinh Tuy commune (Kien Giang Province), many shrimp farmers are adopting bottom aeration systems and reporting clear economic benefits, helping increase income and reduce production risks.
(vasep.com.vn) In the first three months of 2026, Vietnam’s exports of crabs and other crustaceans reached more than USD 93 million, up 23% compared to the same period last year. The result shows that the sector is experiencing a fairly positive recovery, especially in its two key product groups: crabs and swimming crabs. However, behind the growth figures are several concerns: export markets remain highly concentrated, raw material supply is unstable, and trade barriers from the US and EU are becoming increasingly stringent.
(seafood.vasep.com.vn) In Ca Mau province, many farmers are transitioning from traditional methods to high-tech shrimp farming, adopting recirculating systems with minimal water exchange to improve efficiency and reduce risks. In Hung My commune alone, there are about 260 super-intensive shrimp farming households covering more than 265 hectares, playing a key role in local economic development.
(seafood.vasep.com.vn) In the first three months of 2026, Vietnam’s exports of fish cake and surimi reached USD 63 million, down 5% compared to the same period last year. Although total export value declined slightly due to decreases in some key markets, many other destinations continued to post strong growth, opening up room for this convenience-oriented processed segment in the coming quarters.
(seafood.vasep.com.vn) Favorable weather conditions in the early months of 2026 have brought encouraging signs for fisheries activities in Quang Tri. Output has grown steadily, contributing to improved livelihoods for local residents.
Entering 2026, Vietnam’s seafood industry is facing a period of both high expectations and mounting pressures. Following the positive recovery in 2025, production and export activities in Q1/2026 demonstrated the strong adaptability of Vietnam’s seafood business community amid continued global trade volatility, intensifying international competition, and increasingly stringent compliance requirements in import markets.
