Spain's Fresh Fish Shift: Tray Packs Cost More, OCU Finds 2026

Spain's fresh fish consumption is shifting from traditional fishmongers to pre-packaged trays, and a new OCU study reveals that these convenient options often cost more. The Spanish consumer organization found that fish sold in trays can be significantly pricier than similar products from the fish counter, raising questions about value and quality.

What Happened to Spain's Fish-Buying Habits?

In the past, buying fish meant visiting a local market or fishmonger, where you could ask questions, choose your cut, and pay per weight. Today, more consumers are opting for pre-filleted, scaled, and tray-packaged fish from supermarket refrigerators. This shift is partly driven by convenience and changing shopping patterns, with spending increasingly concentrated in supermarkets rather than specialty shops.

The trend has been accelerated by major chains like Mercadona, which has decided to retire its fish counters in favor of pre-packaged offerings. Mercadona holds a dominant market share in Spain, accounting for over 30% of food distribution in some regions, so its move has a significant impact on how Spaniards buy fish.

What Did the OCU Study Find?

The OCU compared prices of pre-packaged fish trays with those from traditional fish counters. The results show that, in general, consumers are paying a premium for the convenience of tray-packaged fish. The study highlights that while the fish may be ready to cook, the cost per kilogram is often higher than buying from a counter.

This price difference is not trivial. For a household that consumes fish regularly, the extra cost can add up quickly. The OCU's findings suggest that consumers should be aware of this premium and consider whether the convenience is worth the extra expense.

Why Does This Matter for Consumers?

The shift to pre-packaged fish has several implications. First, it affects household budgets, as the price premium can strain finances, especially for families that eat fish multiple times a week. Second, it may impact the quality and freshness of the fish, as pre-packaged products may have been processed and stored for longer periods.

Additionally, the decline of fish counters in supermarkets reduces opportunities for consumers to interact with knowledgeable staff and learn about different types of fish, seasonality, and preparation methods. This loss of expertise could lead to less informed purchasing decisions.

Key Takeaways from the OCU Analysis

• Price premium: Pre-packaged fish trays often cost more per kilogram than fish from the counter.
• Convenience factor: The higher price is partly justified by the convenience of ready-to-cook products.
• Market shift: Mercadona's removal of fish counters reflects a broader trend toward pre-packaged seafood.
• Consumer awareness: Shoppers should compare prices and consider buying from counters when available.
• Quality considerations: Pre-packaged fish may have different freshness and handling standards.

What to Watch Next

As supermarkets continue to phase out fish counters, consumers may face fewer choices and higher prices. However, some retailers might respond by offering competitive pricing on pre-packaged fish to attract budget-conscious shoppers. It's also possible that local markets and fishmongers will see a resurgence as consumers seek better value and freshness.

For now, the OCU recommends that consumers stay informed about prices and consider all options. Buying whole fish and having it filleted at the counter, when available, can be a cost-effective alternative. Additionally, frozen fish can be a budget-friendly and nutritious option.
