Why Bimini Fishes Like Nowhere Else

Why Bimini's Bonefish Are Different

Visit Bimini

Most bonefish destinations give you one of three things: size, numbers, or convenience. Bimini is unusual because the geography hands you a version of all three, and it does it for a boring structural reason rather than a magical one. Start with everything on the bonefish itself if you want the species; this is about why these ones are worth a flight.

The island is a hook. North Bimini curls for about seven and a half miles with the ocean on its west side and a vast shallow bank on its east, so the flats are permanently in the lee of something. On a day when the Stream side is unfishable, the flats side is usually fine. And because the island is narrow, “the flats” are not an hour’s run away.

The shape of the island does the work

A flats fishery needs three things: shallow sand, protection from wind, and enough tidal exchange to move food around. The Great Bahama Bank supplies the first at a scale that is hard to picture — thousands of square miles of it, sitting under a few feet of water. The hook of North Bimini supplies the second. Tide through the channels supplies the third.

The flats between South Bimini and the eastern cays have a reputation as one of the best fly permit fisheries anywhere, which tells you something about the quality of the water even when you are not fishing for permit. Where permit thrive, bonefish are usually not having a bad time either.

Why the fish tolerate water that thin

Here is the bit flats articles skip. Bonefish can gulp air into a lung-like extension of the swim bladder, which lets them tolerate water with very little oxygen in it.

That sounds like trivia. It is actually the whole tactical explanation. A shallow sand flat on a hot, still afternoon is an oxygen-poor place — warm water holds less of it, and there is no wave action mixing any in. Most fish of this size leave. Bonefish do not have to, so on the afternoons when everything else has slid off into the channels they are still up there feeding in water under a foot deep. FishBase gives the species a range from the surface down to about 276 ft; in practice on Bimini you are sight-fishing them in ankle-to-knee depth, which is the entire appeal.

The rest follows from that. They are wary because they are exposed. You are casting to a fish that can see you, in water clear enough that it definately can. The typical Bimini fish runs somewhere in the 3 to 8 lb bracket and 18 to 28 inches; FishBase records the species reaching 41 inches and 22 lb, which is bigger than any fish an angler has ever weighed on a certified scale.

The record fish, and what it tells you

16 lb, Jerry Lavenstein, 1971, guided by Ansil Saunders. 33.5 inches long, 19 inches around. Still the all-tackle world record. Still the largest bonefish ever taken on 12 lb line class.

What is genuinely instructive is where. Not a remote cay reached by seaplane — about 300 yards from the Bimini Big Game Club, in sight of the buildings. Whatever produces fish that size was, and presumably still is, operating within walking distance of a bar. We wrote up both of Bimini’s world records and the number everybody gets wrong in more detail, because the bonefish figure in particular is misquoted almost everywhere.

A caution on reading too much into it: one enormous fish from 1971 is a data point about a place, not a promise about your week. Ask the flats guides working out of Alice Town what a realistic day looks like and you will get a straighter answer than any article can give you, this one included.

What changed in 2017

A surprising number of US-facing fishing sites still describe Bahamian bonefishing as though none of this happened. It did, its been the law for years, and it is one of the reasons the fishery still looks like it does. The species is IUCN Near Threatened.

Before you go

The short version of what to sort out

  • Book the guide before the roomGuides are the scarce resource here, not beds. The good ones book out first and they know which flat is fishing.
  • Sort the flats licenceRequired since 2017. Your guide or operator will tell you the current fee and route; we are not going to guess at it.
  • Bring the flat light gearYou are sight-fishing in shallow, bright water. Polarised glasses are not optional and a hat with a dark underbrim helps more than people expect.
  • Expect to be seenGin-clear water cuts both ways. Wading noise and a bad first cast cost you the fish, not just the shot.
  • Plan around wind, not weatherThe lee side is the point of this island. A forecast that ruins the offshore day often leaves the flats perfectly fishable.

If the geology behind all of this interests you more than the fish do, the rest of this section on what makes Bimini fish is the place to start.

Where this comes from

No licence fee and no purchase route appears on this page, because we have not confirmed either against an official Bahamian source. Everything else here traces to the species record below.
