Evidence

Peer-reviewed

Geography

Revillagigedo National Park and adjacent Mexican Pacific

System

Pelagic manta movement; marine protected areas and fishing overlap

## WHAT THE EVIDENCE SAYS

Cabral and colleagues tracked 12 Mobula birostris tagged in the Revillagigedo region between 2017 and 2024\. Over a third of estimated locations lay outside the park; seasonal modeled occurrence extended toward the Gulf of California and overlapped high industrial tuna-fishing effort near reserve boundaries.

## WHY IT MATTERS / OUR READ

An MPA can protect a core habitat while mobile animals still use risky waters around it. Paired telemetry and fisheries-effort data provide a more useful planning basis for buffers and regional coordination than static protected-area area alone.

## CAVEATS / UNCERTAINTY

Small tracking sample, model extrapolation and effort overlap do not directly demonstrate bycatch or a population trend.
