Reef Ball Build FAQs

What is a Reef Ball?

Reef balls are a specially designed artificial reef unit that are used worldwide to build and restore reef habitat. Here in the Chesapeake, reef balls provide important three-dimensional habitat for oysters and many other filtering organisms to attach to. They also provide hollow structure for juvenile fish and crabs to hide from predators. Yes, it’s those predators we pursue as anglers, so reef balls also make some great fishing spots too.
