What is a bonefish?

Bonefish are Florida’s premier game fish are commonly found in intertidal flats, mangrove areas, and deeper adjacent waters. They are also abundant in the Bahamas.

The Bonefish life cycle and behavior are poorly understood.

The spawn lasts from November through May or June, and each female can produce from 400,000 to 1.7 million eggs. Sexual maturity is reached after three to four years (17-18 inches total length), they may live longer than 23 years, and they can grow to be three feet long and 20 pounds. In the Florida Keys, bonefish spawn in deep water.

Bonefish may reach top speeds of 40 mph when escaping from prey or when attached to your fly. It is an awesome site to see your fly line rooster tail as it rips across a flat.

In shallow water, their sharp fins stick out of the water. This spectacular sight is what we anglers call tailing. If we see tailing fish this is one of your best opportunities to hook up. Tailing fish are more spooky and are actively feeding.

In deeper water or when the light is poor, we’ll be looking for muddy areas of water or plumes of mud stirred up by these bottom-feeding fish.

You may also look for “nervous water” which is usually caused by a cruising school of Bonefish on the move – cast in front of the school and strip the fly away from the fish – you may get very lucky.

What does a bonefish look like?

The gray ghost has shiny silver sides and darker often olive green backs which fade into the silver. They often have slightly shaded scales which appear like soft lines that run up the side of the fish from the gills to the tail.

Their pectoral fins are often yellow at the base. A larger saltwater fish, bonefish can resemble a salmon with a slightly elongated snout.

Can you eat bonefish?

They aren’t called bonefish by accident. With a large number of tiny bones, they are difficult to eat and most fly fishing the gray ghost don’t bother to clean and cook the fish. The joy is in the challenge of catching them, so catch and’ release is the way to go.

How to Catch Bonefish?

Fly fishing for these guys can become really complicated, however, I will work with you to teach you the skills you need to master this species. Though it has been considered by many as the most exciting fish of all, very few people are consistently successful in catching bonefish due to their finicky nature.

Though these fish are incredibly elusive and are often referred to as the gray ghosts of the Florida Keys, locating the fish is an easy enough task for your guide. There are multiple places in the Keys they like to hang out to eat, since eating is what they do most of the time. Your guide will take you to the intertidal flats, and deeper adjacent waters and mangrove areas where the bonefish can be found. In shallow waters, the bonefish’s spiky fins will stick out of the water as they feed. In deeper waters, plumes of mud will help you locate the fish as they dig through the silt on the bottom.

This species of sport fish is not only wise but it can easily differentiate between food and the fly. Even a well placed fly that lands quietly, right in front of the bonefish, does not necessarily mean he will eat it. So, it’s always better to become a wise angler if you really want to catch bonefish. Listen to what the experts suggest if you really want to improve your odds. There are some best books about fly fishing on Bonefish, one by Chico Fernandez comes right to mind.

Two important tricks:

  • If you really want to catch bonefish, then you should pay attention to its reaction to your presence and your fly. If you can understand the bonefish’s body language, then you will be able to do what is needed at the right time. Do not cast your fly at fish swimming away from you. Your fly in the water will normally imitate a shrimp or small crab. Bait does NOT swim towards the fish.
  • If you are not stripping the fly correctly, a bonefish may reject your presentation as unnatural. Vary the speed and movement with short strips; mix it up with 4 to 6-inch strips and slightly increase the speed as the fish approaches. It’s the right time to start acting like a shrimp in fear of your life!

Even if the fly lands in the right place and the small shrimp pattern floats at the right level, the bonefish may never even notice your fly. Begin with the small strips as if the tiny shrimp has yet to spot the predator. Again as the bonefish shows interest, increase your speed. If you have caught his eye and everything looks natural, odds are he will inhale your fly. If not, he will turn away like he never even noticed it. There is so much more to learn but the best advice I can give you is to pay attention, practice, and have fun.

elusive how

Elusive How?

Bonefish are slender fish with silvery scales and thin spikey fins; they can blend perfectly into the water and ocean floor when you look at them from above. Bonefish are also incredibly fast. Their bodies are shaped with the aerodynamics of a bullet; they can take off in an instant and jet through the water as fast as 40 MPH!

Bonefish are also suspicious fish and are spooked easily. It takes nothing more than dropping a fly in front of their heads to send them zipping off into the water. This means that not only are they difficult to find, but they’re difficult to catch, period. These are some of the many reasons why these fish are called the “gray ghosts”.
