Scup (Porgy)100
In season (Oct)
Bottom temp 58°F at 98 ft in the prime band (46–70°F prime)
Charted 112 ft suits this species (26–131 ft ideal)
Better near structure or edges if you can find it
Small hooks with squid or worms over hard bottom and mussel beds.
Bluefin Tuna100
In season (Oct)
SST 62°F in the prime band (59–72°F prime)
Charted 112 ft suits this species (82–656 ft ideal)
Temperature break nearby (1.6°C across ~15 nm)
In NOAA-designated Essential Fish Habitat
Troll, chunk or jig where bait stacks on temperature breaks and ledges.
In season (Oct)
SST 62°F in the prime band (59–70°F prime)
Charted 112 ft suits this species (98–1312 ft ideal)
Temperature break nearby (1.6°C across ~15 nm)
Slow-trolled bait or a chum slick where bait stacks on a break — they stun with the tail, so hook-ups run tail-first.
In season (Oct)
SST 62°F workable (63–75°F prime)
Charted 112 ft suits this species (49–656 ft ideal)
Temperature break nearby (1.6°C across ~15 nm)
Small metals or sabikis around bait balls on the edge — a late-summer arrival that draws everything bigger.
In season (Oct)
Bottom temp 58°F at 98 ft in the prime band (46–72°F prime)
Charted 112 ft suits this species (33–148 ft ideal)
No charted structure within 250 m — scored cautiously (charts don't mark all hard bottom)
Squid or clam on hi-lo rigs directly over wrecks, reefs and rockpiles.
In season (Oct)
SST 62°F workable (63–73°F prime)
Charted 112 ft suits this species (16–131 ft ideal)
Temperature break nearby (1.6°C across ~15 nm)
Trolled small feathers or cast metals around bait; moving water.
In season (Oct)
SST 62°F in the prime band (55–68°F prime)
Charted 112 ft suits this species (131–3280 ft ideal)
Temperature break nearby (1.6°C across ~15 nm)
They find the chum slick on their own — circle hooks and a wire bite leader, then let them go.
In season (Oct)
SST 62°F workable (43–59°F prime)
Charted 112 ft suits this species (49–656 ft ideal)
Impossible to avoid once they move in — move off the pack or switch to a bait they cannot swallow.
Tautog64
In season (Oct)
Bottom temp 58°F at 98 ft in the prime band (45–64°F prime)
Charted 112 ft suits this species (13–82 ft ideal)
No charted structure within 250 m — scored cautiously (charts don't mark all hard bottom)
Green crabs tight to rocks, mussel beds and wreck rubble; light tide.
In season (Oct)
SST 62°F in the prime band (54–68°F prime)
Charted 112 ft marginal for this species (3–66 ft ideal)
Better near structure or edges if you can find it
Live bait or plugs on rips, ledges and boulder fields; dawn/dusk moving tide.
In season (Oct)
SST 62°F workable (63–72°F prime)
Charted 112 ft suits this species (131–1640 ft ideal)
Temperature break nearby (1.6°C across ~15 nm)
Chum slick on temperature breaks near bait concentrations.
Bluefish58
In season (Oct)
SST 62°F workable (64–75°F prime)
Charted 112 ft suits this species (7–98 ft ideal)
Metal lures or poppers through bait schools and birds; wire leader.
