When gag are around Marco Island
Gag grouper fishing out of Marco Island is bottom fishing on offshore reefs, wrecks and rocky structure in 40 to 100 feet of water. Timing depends on which source you read, because the one local listing that addresses it gives two different answers. For the whole coast, see the Gulf of Mexico fishing guide.
What the Wild Thing listing says
Wild Thing Charters puts the best fishing in spring through fall, when the fish are most active. The same listing names October through March as the most active months.
We haven’t tried to reconcile the two. Plan around the depth band and the forecast conditions, and check the season status with FWC before you go. How gag move through the year beyond this port is covered in our gag grouper guide.

Where boats run and what holds the fish

Gag off Marco Island hold on reefs, wrecks and rocky structure in 40 to 100 feet.
The 40 ft line
The gag water starts at about 40 ft, so begin on structure near that depth. Running out past it leaves the inside edge of the band behind.
Out to 100 ft
The band runs out to 100 ft. When the inside marks give you nothing, work toward the deep end, one piece of structure at a time.
Reefs, wrecks and rocky bottom

Reefs, wrecks and rock are what you’re looking for on the sounder. Open bottom between them is just transit. Gag are a structure fish, and the NOAA Fisheries gag profile places them on reefs, wrecks and ledges.
The Marco Reel and Shore Charters listing names gag grouper for Marco Island waters. For the wider Southwest Florida picture, see our Gulf reef fish guides.
In Breakpoint, Chart Contours shows where the 40 and 100 ft contours sit relative to the pass. Chart layers are not for navigation, and contour data shows depth, not whether a ledge holds fish. Check the NWS marine forecast for wind, wave height and period before the run.
| Depth | What it means for the day |
|---|---|
| About 40 ft | Inside edge of the gag band. Start on structure here |
| 40 to 100 ft | The working band for reefs, wrecks and rock |
| 100 ft | Outer edge of the band. Work toward it when inside marks are empty |
