In 2023, the production value of alive fresh crabs and sea-spiders in capture fisheries in France was valued at the equivalent of 2.90 thousand euros per metric ton. The forecast for 2024 to 2028 indicates a gradual increase, beginning at 2.97 thousand euros per metric ton in 2024 and expected to reach 3.27 thousand euros per metric ton by 2028.

The year-on-year growth demonstrates a steady upward trend, with an average annual increase of approximately 2.4% from 2024 to 2028. The compound annual growth rate (CAGR) over this five-year period is projected to be about 2.91%, reflecting a healthy and consistent growth rate in production value.

Future trends to watch for include:

Potential impacts of climate change on marine biodiversity which could affect capture yields.
Shifts in consumer demand and preferences towards sustainable and locally-sourced seafood.
Regulatory changes in fisheries management that might influence production practices and volume.
