Sustainable technical-production model (bioeconomy) for the sustainable cultivation of Chondracanthus chamissoi in La Libertad (Peru)

Abstract

This research develops a technical-production model for the cultivation of Chondracanthus chamissoi (Yuyo) in the La Libertad region of Peru. Socioeconomic, environmental, and extractive pressure factors on natural beds were integrated. Primary information was obtained from the La Ramada Artisanal Fishermen's Association (APDAR), along with laboratory data on vegetative propagation and suspended systems, and evidence of macroalgae harvesting dynamics according to the DPSIR framework. The results showed that implementing in-line cultivation systems achieves controlled production, reduces pressure on natural resources, and generates added value. The financial evaluation indicates the need for scaling up and product diversification to achieve profitability. This model contributes to strengthening community governance and blue bioeconomy strategies.
