Atlantic Bonito
Sarda sarda. Prime water reaches Casco Bay in New England right now (63°F at the surface). Fish it 0–60 ft down — that is where 73–71°F water sits off Montauk.

The water column off Montauk
The strip is the water itself, coloured by temperature from the surface down to the 60 ft surveyed bottom at that spot — one band per RTOFS model level. The outlined stretch is where Atlantic Bonito's temperature band (63–79°F) and the depth it holds actually overlap. That thickness is the number that matters: it is how much water you can work, not just whether the spot is warm enough somewhere. One model cycle, not a weekly archive — this holds still while the surface map scrubs.
How it's fished
Trolled small feathers or cast metals around bait; moving water.

"Fish it at" is where this species' temperature band and its holding depth overlap in the water column, from the RTOFS profile (13 levels, 0–300 m) — the depth to actually put a bait, not just the place. "Prime water" is the furthest sampled station on the 10-fathom lane whose surface temperature sits inside this species' band. It is water, not a sighting report.
