SEA Aquaculture & Seafood:
Competitive Field Map 2026

Southeast Asian aquaculture operates as a commodity-to-premium conversion industry. Raw shrimp, pangasius fillets, and tuna move from farms and vessels through processing into certified, packaged export products. The companies that control the most steps in that chain — feed, hatchery, grow-out, processing, cold chain, and distribution — set prices, absorb margin shocks, and survive tariff disruptions. Those that only control one or two steps are price-takers. This is the single structural truth that explains every competitive move in the region.

Buyer power is high and concentrated. A small number of US, EU, Japanese, and Chinese importers and retailers control access to the highest-value markets. These buyers specify certifications (HACCP, ASC, GlobalG.A.P), require traceability documentation, and can redirect purchasing to India or Ecuador within a season if a supplier fails an audit. The 2025 US tariff changes — 20% on Vietnamese shrimp, 19% on Indonesian shrimp — demonstrate how quickly buyer geography can shift when external conditions change[Southern Shrimp Alliance].

Supplier power is moderate. Feed costs, fingerling quality, and cold-chain logistics are concentrated inputs, but multiple suppliers compete in each category across the region. The Asian Development Bank's cold-chain infrastructure investment, which specifically benefited CPF's frozen seafood operations[Mordor Intelligence], illustrates how infrastructure access can temporarily tip supplier dynamics in favour of integrated players.

The competitive field divides into two tiers. The first tier is two Thai-headquartered integrated conglomerates — Charoen Pokphand Foods (CPF) and Thai Union Group — that control supply chains from feed and hatchery through retail branding in multiple countries. The second tier is Vietnamese export specialists — Minh Phu, Vinh Hoan, and Nam Viet Corporation — that compete on certified volume, trade-agreement pricing, and category depth in shrimp and pangasius respectively.

CPF operates Asia's largest integrated shrimp complex, combining hatcheries, feed mills, farms, and processing under one ownership structure[Precedence Research]. This vertical integration means CPF absorbs input cost shocks that fragment less integrated competitors. Thai Union holds global consumer brands — John West, Sealect, Chicken of the Sea — that command shelf presence in Western retail independent of spot commodity pricing[just-food.com]. The Mitsubishi equity raise to 20% in August 2025 locks in stable procurement relationships across canned tuna, frozen salmon, and shrimp and signals that global trading houses view Thai Union's model as the region's most durable.

Vietnamese producers compete differently. Minh Phu wins on shrimp volume and EVFTA tariff access — EU-bound shrimp from Vietnam carries preferential tariff treatment that Indonesian and Thai rivals cannot match for EU buyers. Nam Viet (Navico) posted VND 2 trillion (approximately US$75.9 million) in Q3 2025 revenue, up 49% year-on-year, driven by pangasius recovery in China and Japan[Vietfish]. Vinh Hoan is the premium-positioning player in pangasius, targeting higher-value fillets for US and EU retail — though US tariff exposure is a real headwind heading into 2026.

Export contracts in this market are won at the intersection of four factors: holding the right certifications, accessing trade-agreement tariff reductions, operating verified traceability systems, and maintaining cold-chain reliability. Price matters — but only after a supplier clears all four gates. A Vietnamese shrimp exporter without HACCP certification cannot bid for EU retail supply regardless of price. An Indonesian processor without a compliant IUU (illegal, unreported, and unregulated fishing) documentation chain cannot access certain US buyers following NOAA's September 2025 Marine Mammal Protection Act comparability denials for Indonesian fisheries[NOAA].

Vietnam's EVFTA agreement gives Vietnamese shrimp exporters a structural tariff advantage in the EU that Indonesian and Thai competitors cannot match. CPTPP membership extends this to Japan, Canada, and Australia. For Minh Phu, this tariff access is the primary reason EU buyers choose Vietnamese shrimp over lower-cost Ecuadorian product — the landed cost after tariffs is competitive even at higher farmgate prices. Vietnam's shrimp exports to India — a market with no equivalent tariff benefit — grew 2,492% by volume in the first seven months of 2025[Vietfish], showing that when trade barriers fall, volume follows almost immediately.

Vietnam's whiteleg shrimp farmgate prices rose continuously through July 2025, with commercial sizes (30–40 pieces per kg) increasing by VND 20,000 per kg over two weeks ending July 20, driven by factory purchasing and sentiment around US tariff delays[Vietfish]. In Thailand, whiteleg shrimp farmgate prices (size 80 pieces per kg) fell by 5 baht per kg in the second week of January 2026 following flood recovery, with January production running at 12,000–16,000 tonnes[Vietfish]. No equivalent farmgate data is publicly available for Indonesia or Malaysia, and no company-specific processing or export price data is available for Vinh Hoan, Stapimex, or any named Malaysian operator — these firms do not publish price schedules.

The more important pricing dynamic is the export price divergence across destination markets. Vietnam's whiteleg shrimp exported to China averaged USD 7.2 per kg in early 2025 (up 9.1% year-on-year despite volume falling to 1,637 tonnes), Japan averaged USD 9.5 per kg (up 5.6%), and South Korea averaged USD 8.0 per kg (up 5.3%)[VASEP via Vietfish]. Premium markets pay more — Japan's price premium over China reflects the value-added shrimp specification that Japanese buyers demand. No named company is publicly identified as using price discounting as an active competitive weapon; the evidence instead shows that producers are competing on certification access and buyer diversification rather than margin compression.

Vietnam's export quality record carries documented weaknesses that its competitors — particularly Indonesia and the Philippines — can exploit directly. China blacklisted 15 Vietnamese seafood companies in 2019 for excessive polyphosphate in frozen products, and returned 52 batches from 36 enterprises in March 2022 for SARS-CoV-2 detection[PMC]. The result: Vietnamese seafood exports to China declined across 2018–2024 while Indonesian and Philippine exports to China grew over the same period. This is not a historical footnote — it is an active market-share transfer in progress.

Indonesia faces its own compliance pressure on a different front. NOAA denied Marine Mammal Protection Act comparability findings for subsets of Indonesian fisheries on September 2, 2025[NOAA], meaning certain Indonesian seafood categories face US import restrictions. For Indonesian producers targeting the US market, this regulatory finding is a material obstacle that Vietnamese competitors — who are not subject to the same MMPA determination — can use as a differentiation argument with US buyers, even while both countries face shrimp tariffs.

The strategic implication is clear: the quality and compliance battleground is not symmetrical. Vietnam is most vulnerable in China, Indonesia is most vulnerable in the US, and the companies that invest in audit-ready traceability systems and proactive certification renewals — rather than treating compliance as a cost to minimise — will convert rivals' rejections into their own volume gains.

Battle one is US shrimp import share. India held 38% and Ecuador held 29% of US shrimp imports in 2025[USDA via S&P Global]. Vietnam held 8% (down 12.5% year-on-year) and Indonesia held 15% (down 8.7% year-on-year). The 20% tariff on Vietnamese and 19% on Indonesian shrimp makes recovery of US share mathematically difficult unless those tariffs are renegotiated or the quality-certification gap with India narrows enough to offset the price differential. Vietnam's best response — already visible — is accelerating into India, where it became the second-largest seafood supplier in 2025[Vietfish] and shrimp exports grew 2,492% by volume in January–July 2025.

Battle two is the China channel. China's food safety scrutiny pushed Vietnamese exports lower while Indonesia and the Philippines grew. The companies that win this battle will be those that invest ahead of China's traceability and residue standards — not those that react after a rejection. No named Malaysian operator appears in available data for either of these battles, which is itself a finding: Malaysia is not currently a visible competitor in the high-volume export categories that define this market's competitive structure. Battle three — the integrated feed-to-farm premium segment — is CPF's home ground, but Thai Union's Mitsubishi alliance signals that branded premium products are the long-term defensive moat against commodity price pressure from Indian and Ecuadorian volume players.

The Mitsubishi Corporation equity raise in Thai Union — announced August 4, 2025, moving Mitsubishi from 6.19% to 20% at Bt12.50 per share for a total additional acquisition of 532.27 million shares[just-food.com] — is the only confirmed major strategic capital event in the region from a named major player between January 2024 and Q2 2026 based on available evidence. The deal covers more than 30 years of collaboration and spans canned tuna, pet food, frozen salmon, and shrimp. It signals that Mitsubishi is treating Thai Union as a long-term strategic platform, not a passive portfolio holding.

No confirmed acquisition, capacity expansion, technology investment, or new market entry announcements were identified for CPF, Minh Phu, Vinh Hoan, Navico, or any named Malaysian or Philippine operator during this period. This absence is a finding in itself: the Vietnamese producers are navigating tariff disruption and compliance investment rather than making offensive capital moves, while the Thai integrated players are consolidating. The competitive implication is that the gap between tier-one integrated players and tier-two volume exporters is likely to widen over 2026–2027 as capital compounds integration advantages.
