Zambales Adds Two Marine Sanctuaries to Boost Fish Stocks

"Through the network system of marine protected areas, Zampan aims to develop strong biodiversity in coastal areas and expect a natural increase in fish population," Pablo said.

Scientific studies show that well-managed protected zones increase fish biomass inside the boundaries and generate a "spillover" effect, where adult fish and fingerlings move into adjacent fishing grounds. That helps maintain a steady seafood supply and supports coastal livelihoods, the DENR said.

Lawyer Marife Castillo, provincial head of DENR-Zambales, said the two sites were endorsed because of their high ecological value as coral reef ecosystems. They function as breeding, spawning, nursery, and feeding grounds for various marine species.

"The two marine protected areas were endorsed for inclusion because of their ecological importance as coral reef ecosystems that serve as breeding, spawning, nursery, and feeding grounds for various marine species," Castillo said. "Protecting these areas as part of a larger network strengthens habitat connectivity, improves ecosystem resilience, and supports coordinated management of coastal resources across municipalities."

The resolution provides a framework for coordinated action among member-stakeholders, the DENR said.
