Reef school

Bermuda sits near 32°N — far outside the tropics — yet grows a true coral reef because the Gulf Stream carries warm water past the island year-round. The result is a shallow platform many times larger than the land itself: a rim reef ringing the north, patch reefs scattered across the lagoon, and terraces that drop off into deep water at places like Challenger Bank and Eastern Blue Cut.

Because the island is isolated, the reef has fewer coral and fish species than the Caribbean, but the ones that live here are unusually abundant and often unusually large. It also means nothing recolonises quickly. A species fished out around Bermuda does not simply drift back in from next door — that isolation is the single biggest reason the island's fishing rules are strict.

Parrotfish scrape algae off coral and grind dead coral rock into sand. On a reef where algae would otherwise smother young coral, they are the maintenance crew — and Bermuda's famous beach sand is largely their by-product, mixed with the pink of crushed red foraminifera shells. Bermuda has protected parrotfish for decades, and taking one is illegal.

That's why spearing one in the game costs you 30 points and breaks your combo. The penalty is the lesson: on the water, letting a fish swim is sometimes the whole skill. Check every protected species on the species guide.

Indo-Pacific lionfish appeared in the western Atlantic in the late 20th century and reached Bermuda in the 2000s. They have no natural predators here, breed year-round, and eat juvenile reef fish at a rate native species can't absorb. Bermuda actively encourages culling, and licensed divers are a real part of the control effort.

Handle them carefully: the venomous spines are on the dorsal, pelvic and anal fins, and a sting means hot-water immersion and, if it's bad, a doctor. The flesh is not venomous and is genuinely good eating. In the game, lionfish spawn often and score well — that's deliberate.

Nassau grouper and other large groupers gather in the same places at the same time each year to spawn. Those aggregations are predictable, which makes them easy to wipe out — the reason Nassau grouper is now protected across much of its range, Bermuda included.

Bermuda's most drastic conservation move came in 1990, when the island banned commercial fish pots outright after reef fish stocks collapsed. It was a painful decision for local fishermen and it is the backdrop to everything that followed: seasonal closures, protected areas, and a licence system that keeps spearfishing a small, resident, low-impact activity. The licence guide covers how that applies to you.

The inshore waters, bays and sounds are the nursery. Juvenile snapper, grunts and grouper shelter in seagrass beds and mangrove edges before moving out to the rim reef as adults. Keeping spearfishing at least one nautical mile from any shore protects that nursery ground, separates spearfishers from swimmers and snorkellers, and pushes the activity onto deeper reef where fish are mobile and harder to take. It is a habitat rule as much as a safety rule.

Three habitats cover most of what you'll swim over. Turtle grass flats hold juveniles, conch and rays, and the sand-to-grass edge is where predators patrol. Patch reefs — isolated coral heads on sand — concentrate fish tightly; circle them once, quietly, before committing. The rim reef and drop-off bring current, bigger schools and pelagics like jacks, wahoo and tuna moving through.

Each level in the game is built from a real one of these: Somerset Long Bay's shallow flats, North Rock's rim reef, the Constellation wreck, Eastern Blue Cut and Challenger Bank. The species mix changes with the terrain, exactly as it does on the water. See the dive sites map.

Hundreds of ships have gone down on Bermuda's reefs over four centuries — the platform sits just below the surface, miles from land, and for most of history there was no way to see it coming. Those wrecks now act as artificial reef: hard structure on open sand that collects encrusting growth, then baitfish, then predators. Morays live in the plating, triggerfish patrol the ribs, and snapper hang in the shadow of the hull.

Many wrecks are protected historic sites. Look, don't take, and don't disturb the structure — the rules on protected dive sites are separate from the fishing rules and apply year-round.

Water temperature swings from the high 60s°F in late winter to the mid 80s°F in late summer, and the fish move with it. Summer brings warm, clear water, long flat spells and pelagics on the banks; winter brings cold fronts, swell from the north and fish holding deeper. Spiny lobster has a defined open season and must be taken by hand or noose — never by spear. Seasonal closures shift, so confirm the current dates before every trip on the season calendar and with DENR.

Ice the catch immediately — a fish left in a warm bilge is a wasted fish. Take what you will eat that week and no more; the reef is small and everyone fishes the same platform. Be aware that some large predatory reef fish in tropical Atlantic waters can carry ciguatera toxin, which cooking does not remove, so follow current local advice on which species and sizes to avoid.

The Bermuda Aquarium, Museum & Zoo and the Bermuda Institute of Ocean Sciences both publish accessible material on the island's reef, and the Department of Environment & Natural Resources holds the current fisheries regulations, protected species lists and closed areas. When this page and the regulations disagree, the regulations win.
