The total periwinkle production in capture fisheries in France has shown a slight declining trend from 2024, with values forecasted to decrease from 4.74 to 4.60 thousand euros per metric ton by 2028. This represents a gradual decrease of approximately -0.85% per year on average over the forecasted period. As of 2023, the actual value stood slightly higher, indicating a subtle annual decrease going forward.

Future trends to watch for include:

Potential impacts of climate change on marine ecosystems, which could affect periwinkle populations.
Shifts in consumer demand and market preferences that may influence production levels.
Regulatory changes in fisheries management, potentially affecting harvest limits and production costs.
