The Pasco Banks refers to a naturally occurring geological and marine formation in the south Pacific Ocean. The Pasco Banks is a long ridge-like seamount that rises from about 200 m to within 30 m of the ocean's surface. Covered in patchy coral reef, it attracts large schools of baitfish, mainly rainbow runner, which in turn are preyed upon by larger predatory fishes. This abundance of fish has made the Pasco Banks a popular and reliable fishing location for hundreds of years.
