In 2023, the production of whole fresh purple dye murex in capture fisheries for human consumption in France was a notable baseline for the subsequent forecasts, standing at a certain value that led to the following projections. From 2024 to 2028, production is forecasted to gradually decline from 21.4 metric tons to 20.5 metric tons. This represents a year-on-year decrease, with decreases being relatively minor each year but consistent: -1.40% in 2025, -1.42% in 2026, -0.96% in 2027, and -0.49% in 2028. Over the five-year period, this trend reflects a modest compound annual growth rate (CAGR) decline, indicating a slow but continuous decrease in production.

Future trends to watch for:

Environmental changes and how they impact marine biodiversity and, consequently, murex populations.
Potential regulatory changes targeting sustainable fishing practices that could impact production volumes.
Market demand shifts driven by consumer preferences for sustainably sourced seafood products.
Technological advancements in aquaculture that might offer alternatives to traditional capture fisheries.
