Spotted sea trout go deep when the mercury falls below 40° F in east central Florida and anglers that are in-the-know will pursue them in the deep water canals and holes in the Indian and Banana River Lagoon on the coldest winter days.
Fish Deep Holes
Growing up on Florida's Space Coast I learned from long time veterans the best holes frequented by anglers for large trout often referred to as "
gator trout". Most of the holes are now accessable only by boat as private land have been developed and closed to the public. Some of the best holes are located in security areas around Kennedy Space Center and Canaveral Air Force Base. One productive deep hole is nestled between the shuttle recovery ships in the Banana River Lagoon's north end where up the 1980's fishermen simply pulled up next to and dropped a line for literally hundreds of spotted sea trout. I suppose that they consider the ships a terrorist target as homeland security and the federal government has made a huge perimeter around Kennedy Space Center capturing thousands of acres of public land and waters.
Find Healthy Habitat Nearby
Florida's inshore lagoons average less than five feet deep and most deep holes are man-made canals or dredged up channels. The best trout holes seem to be in canals where the water can stratisfy or thermocline and the trout can lay in the deepest and coldest depths where temperatures are stable. Many anglers believe that the trout are going deep for warm water but contrary to this misconception, cold water sinks as soon as the wind and air cool it down above. It's this cold water thermocline that the sea trout like while they lay still for a day or two until the Florida sunshine state warms the water again. When scouting for deep holes you want to look for direct access of the lagoon and close to health grass flats, this makes sense because fish need a healthy habitat to live in before the cold fronts and trout love clear grassflats with lots of food.
Use Live Finfish for Bait
I often probe wintertime trout holes with artificials (trout touts,mister twister tails,jigs, etc...) that get down deep until I find concentrations of fish, then I switch to live bait. Work artificials slow and on the bottom, trout are subtle biters when it's really cold, as the warms up they will become more agreesive feeders and feed above the thermocline. I've had days when you could catch over 100 ten inch trout on grub tails but if I had used live bait similar to mud minnows, finger mullet or mojara we would have scored much bigger fish.
TIP: Avoid using shrimp if you want big fish. Everything from pinfish, catfish and small trout will eat your bait up. While it's true you can catch large trout on shrimp you'll supersize your fish on finfish bait.
Light Tackle's the Secret
Six pound test on a sensitive rod makes for a great wintertime trout rod. A light rod can bring in any gator trout in the winter and you'll improve your success with more hookups. Use 15 pound test flourocarbon leader tied on with your favorite fishing knot (avoid swivels) and use a good sharp hook. Don't us a bobber if you can avoid it because the really big trout seem more tackle shy.
Good Luck Fishing
