Fishing the Florida Keys - Basic Dolphin Fishing Tips
by Captain Dallas

Dolphin a.k.a. Mahi Mahi, Dorado and Dolphin the fish, are really the perfect game fish as told
by Capt. Jim Sharpe, in his book, Dolphin, The Perfect Game Fish. Few are more acrobatic,
colorful or tasty, than the Dolphin. In the Florida Keys they can be caught any month of the year.
April through May are considered the best months for big Dolphin, June through August can be
great fishing for slammers as well. Slammers, Dolphin over thirty pounds are plentiful in these
months but are often lost in the huge schools of peanuts or schoolies that are everywhere.
Techniques used for catching these beautiful fish varies a little from captain to captain, but it all
boils down to one thing, Find The Fish!

Most of the east coast has access to the Gulf Stream, which flows anywhere from 5 to 75 miles
off the coast. This is the zone where the blue water pelagic species, Billfish, Wahoo, Tuna and
Dolphin are found. In the Keys it is a little different, when water temperatures are uniform all
over the Florida Straits, pelagic fish can be found anywhere. A Sargasso weed line found off
Georgia will, almost always produce in May. Here in the Keys you may cross twenty weed lines
before you find fish. So here are a few tips:

Surface water temperature: Any significant water temperature variation can hold fish. Typically,
the higher the temperature, the better the bet. Look for a minimum of 74 degree and a
maximum of 84 degrees water temperature. This has been my best temperature range. That’s
why the Gulf Stream is the spot to fish. In the Keys more often than not, this holds true as well.
But bayside water flow will create color changes anywhere from the edge of the reef to five
miles past the reef. These color changes, green to blue, or power blue to cobalt blue are hot
spots not to be over looked.

Weed lines: Sargasso weed is the ticket. Sargasso is living, floating vegetation that is full on
life. If you find a good weed line that is alive, meaning you see bait in the line, there will be fish
somewhere. Grass lines, created with a variety of bay grasses, are dead vegetation. Dying
grass will hold little bait and therefore little fish. Every year, people catch a few fish in these
grass lines, but the proper weed line will blow a grass line away. Look for the good stuff.

Eddy currents: Whether created by one of the Humps south of the Keys or by changing flow in
the Gulf stream current will hold fish and normally big ones. Most of the eddy currents will be
near a surface water temperature change.

Floaters: Floating debris is the most popular Dolphin indicator. Older floaters loaded with
barnacles and bait are usually a Dolphin gold mine. But don’t overlook smaller floaters, like
coconuts, trap buoys with line trailing down, or just a bucket or board. These can all hold fish.

The problem in the Keys is that a beautiful weed line or a fantastic floater, can move over the
reef on one tide and back out offshore with the next. The reef fish, yellowtails, mackerel, jacks
and chubs will eat everything out of the line and the line will hold squat. Look for bait in your line
before devoting your whole day to trolling it. Birds, working the weed line is a good clue you
may be in the right place.

As for birds, Frigates and Sooty Terns are the best to watch. Any type of tern is worth a look, but
the Sooty terns don’t get wet, they rely on the predator fish to drive bait to the surface. Bigger
fish normally have fewer birds. Hundreds of terns will normally be on a school of tuna or
smaller dolphin. One or two terns lazily following a weed line are normally on a few bigger fish.
Any frigate is worth a look, the lower the better, but if it’s slow, try following a high flier. Their
eyes are a lot better than yours. They will normally see the bait sprays first.

Just about any bait you can think of will catch Dolphin. Ballyhoo are the number one bait used
with straight plastics the second. I normally fast troll (7 to 10 knots) smaller plastics lures until I
find fish then switch to ballyhoo if the plastics aren’t working, which is pretty rare. Having pitch
rods rigged with ballyhoo or a nice, fat live bait, are a must. Most of my bigger fish have been
hooked sight casting to a bull following a smaller fish hooked while trolling.

Bailing schoolies normally goes something like this, keep a hooked fish in the water and catch
as may of his buddies with bait chunks on spinning tackle, as you like. Start with about five foot
of leader and a 5/0 to 7/0 hook and a chunk of ballyhoo or squid. Keep that pitch rod rigged and
ready for another big boy, just in case.

Dolphin fishing requires a bit of hunting. All of what I said before can be lumped into one thing,
find something different. I highly recommend you check out a copy of Capt. Jim’s book and get
down here to do some catching.
