Blue marlin fishing out of Indian River Inlet runs from late May through August, and boats troll for them on the offshore grounds reached from the inlet. According to the Indian River Marina fishing reports, the fish here are mostly released, with some boated for tournaments. This guide covers the season, the run, and the structure so you can plan the day. Inlet, ramp and marina details are on the Indian River Inlet port page.
Blue marlin season at Indian River Inlet
The season runs late May through August, so offshore days should fall inside that window. Tournament fishing happens in the same stretch, which means your trip dates may overlap with local events. For how the fish live and move, see the blue marlin species guide.
- Start: late May
- End: August
- Method: trolling on offshore water
How far boats run from the inlet
Blue marlin fishing here happens on the offshore grounds reached from the inlet. No single named ground is tied to the species, so the thing to plan is the run rather than a particular spot.
An 18-mile reef and a 35-mile canyon are different days for fuel and weather, so build the plan around the farthest water you intend to fish. Massey’s Canyon, about 35 miles offshore per DNREC, is the farthest named structure in the table below. For the wider canyon picture, see the Northeast Atlantic blue marlin guide (see also the Atlantic Northeast offshore fishing guide).
Run distance sets the shape of the day:
- Nearshore reefs: a short hop that fits an early start.
- Mid-distance grounds: reefs and wrecks in the 13 to 28 mile range.
- Canyon water: the longest run, and the biggest call on fuel and weather.

How blue marlin are fished here
Local boats troll for blue marlin.
Trolling
Trolling is the local method. Boats work the offshore grounds reached from the inlet and let the spread do the searching. Spreads and setups are covered in our billfish guides.
Releases and tournament fish
Blue marlin are reported as releases, with some boated for tournaments. Catch and release is the usual outcome, and billfish tournaments account for the fish that come to the dock.
Who fishes for them follows from that:
- Anglers who troll and release: the common approach here.
- Tournament teams: they boat some fish.
