Overfishing of the black sea urchin’s native predators has allowed this species to grow without natural checks, threatening the balance of marine ecosystems along the coast of central Chile.
Artisanal fishers in the Ventanas and Zapallar coves have managed to curb the population growth of this species and recover marine biodiversity.
They have done so by protecting their TURF-Reserves, areas they themselves have declared off-limits to fishing so that marine life can recover.
The decline of the black sea urchin has allowed kelp to return, followed by a large-scale return of fish, mollusks and macroinvertebrates that enrich local biodiversity.
