Peruvian Fishermen Revive Sea Urchin Population Through Self-Regulation

Fishermen in Matarani and Mollendo, Peru, have successfully recovered a depleted red sea urchin population through a decade of self-imposed restrictions and collaborative management. Facing dwindling urchin numbers due to overfishing prior to 2014, 156 members of seven fishing organizations voluntarily halted extraction for two years, allowing the species to rebound.

This initiative went beyond a temporary pause. The fishermen established “sacas”, seasonal, regulated harvests based on market demand, and actively monitored the ecosystem alongside the Peruvian Sea Institute (Imarpe).

Their success has led the Arequipa Regional Government to approve a plan granting them exclusive rights to sustainably harvest urchins, along with octopus, abalone, and keyhole limpets, in a 231-hectare area. This agreement serves as a model for sustainable fishing practices in Peru and demonstrates the power of community-based conservation. The fishermen are now working to establish a baseline for the managed area, ensuring long-term monitoring and protection of the marine ecosystem, contributing to Peru's commitment to the 30x30 conservation goal.
