Mangrove snapper, snook, jacks, tarpon, barracuda, sheepshead, redfish and even big sharks wander throughout the intra coastal waterway.
Too much to type so i'll cut & paste a little of my favorite intracoastal fish of which i'm embarrassed to say that I haven't fished for in over a year,
Snook-
The best snook bite is usually within an hour or two either side of sundown. Live shrimp, mullet or pilchards are the bait of choice for snook. Snook are a very cunning fish that live in the shallow waters around jeddies, dock and piers and areas of good bottom structure. Snook are cautious fish and eat only when you entice them with something they just can’t do without. Shrimp are their favorite food and make up much of their diets. Shrimp typically bury themselves during the day and rise up to the surface at sundown to feed. When the snook are around, they are looking for some tasty shrimp to go floating by.
A big side note though- the regulations are constantly changing it seems like with this species so check before you decide to keep one because they do have a "season" and you do need a stamp.
Here's a little more cut & paste info-
Barre none, Snook is the best fish in the world to catch. That's my personal opinion. To me, it's one of the best tasting fish out there.
Snook is also one of the most regulated fish as well. When I was in law enforcement, I think I saw guys do more time for illegal snook fishing than I did for armed robbery! ( That aint no lie! )
In Florida, the law forbids ANY kind of commercial fishing for this species of fish. They also regulate specific seasons, size limits, and bag limits. If you violate ANY law on these fish, you will go to jail, possibly have your vehicle or boat confiscated, and face heavy fines. So you have to be careful about that.
Snook are an ambush fish. They like to spring out from cover and attack their prey. Use this to your advantage, and you will catch them.
I used to find snook in the mangrove trees along the banks of salt-water rivers, as well as in the inlets, and along jetties on the ocean. You were permitted to catch and keep any snook over 23 inches........bag limit of 2 per day. You measured the fish from the snout to the "V" in the tail. If you were even a fraction of an inch off in your measurement, you might go to jail that day. So make sure you bring a measuring tape with you and be on the safe side.
My rig for snook was a medium rod and reel, loaded with 30lb test line. Connected to that line was a swivel and 18" of 20lb monofilament leader, and a "snook hook" on the end. The lead weight you would use would be connected to the swivel, and the size would be determined by how fast the current was where you were fishing.
The object is to have the lead weight sit on the bottom, and "float" your bait above it.
Preferred bait was a live large shrimp, hooked between the "horns", to keep it just that......alive. You wanted it kicking. You would also need a bait bucket that had an air supply to it to keep the shrimp alive. You can also catch snook on a fly rod, but I never got into that.
When a snook strikes, expect the fight of your life. This is what makes snook fishing so popular, almost an addiction in Florida.
I repeat- A big side note though- the regulations are constantly changing it seems like with this species so check before you decide to keep one because they do have a "season" and you do need a stamp.
