FranceAgriMer's price and margin observatory study reveals insights into the price formation of seafood products in France, covering various stages from production to distribution and export. The report highlights a decline in seafood production and auction prices in 2020 due to reduced fishing activities and restaurant closures, yet offset by lower diesel prices. Import prices have been on a downward trend for three years. The examples of saithe and smoked salmon detail changes in retail prices, margins, and the increasing importance of imports. Both examples show a decrease in the supermarket margin to avoid passing on upstream price increases, indicating a shift in the value chain for these products.
