Divergent Outcomes at Dutch Fish Auctions: European Plaice Weakens in Small‑Medium Sizes, Sole Rises Across All Grades
Introduction
Week 16 2026 brought sharp divergence at Dutch seafood auctions. Most sizes of European plaice dropped in price, while European sole climbed across every grade. Though both are European flatfish groundfish, the two species delivered opposite market performances, laying bare gaps in landing volumes and market demand absorption capacity.
European Plaice: Small‑medium Sizes Fall, Large Sizes Buck the Trend
Price declines were concentrated in gutted‑iced plaice of mainstream small‑medium sizes: ‑ 35‑41 cm:‑1.20 EUR/kg week‑on‑week ‑ 31‑35 cm:‑0.40 EUR/kg week‑on‑week ‑ 27‑31 cm:‑0.75 EUR/kg week‑on‑week ‑ 41‑80 cm large size: +0.45 EUR/kg week‑on‑week
The 27‑31 cm segment represents the highest‑volume trade size. Landings for Week 16 rose by 7% week‑on‑week to 5.9 tonnes (still‑27% year‑on‑year). Higher arrivals for this dominant size group weighed heavily on prices. Scarcer large‑size landings kept its price well‑supported. This is not a full‑scale plaice market collapse; pressure falls mainly on high‑volume small‑medium specifications.
European Sole: Supply Contraction Drives Broad‑Based Price Gains
Over the same week, auction prices for gutted‑iced European sole advanced across all sizes with no segmentation gap. Landings for the key 27‑30 cm sole fell 20% week‑on‑week to only 2.5 tonnes, a steep 38% drop year‑on‑year. Tighter supply combined with solid buying interest lifted prices uniformly across grades, showing stronger market appetite for sole versus plaice.
Market Insight
Contrasting price movements for two groundfish species within the same auction venue reveal clear shifts in buyer preference. Beyond Dutch domestic catches, plaice supplies from Danish Baltic vessels plus German and UK fishing fleets are exposed to these market dynamics. Week 16 auction data sends a clear signal: mainstream plaice sizes face price pressure, whereas the sole market remains firm.
