Marine Protected Areas are supposed to protect ocean ecosystems, rebuild fish populations, and safeguard biodiversity. Today, more than 8% of the global ocean is officially classified as protected. But if protection is increasing, why are sharks, reef fish, and other marine species still declining in many of these areas?

In this episode of Ocean Decoded, marine biologist Andrew Lewin breaks down the reality behind marine protected areas. You will learn what an MPA actually is, why some protected areas succeed, and why many others exist only on paper. These so-called “paper parks” are designated zones that lack enforcement, funding, or clear regulations, meaning fishing and extraction can continue even inside protected boundaries.

This episode explains the science behind effective ocean protection, including enforcement, monitoring, and the spillover effect where healthy fish populations rebuild inside reserves and benefit nearby fisheries. If we want marine conservation to work, the difference between symbolic protection and real protection matters.
