The water column off Penobscot Bay
The strip is the water itself, coloured by temperature from the surface down to the 210 ft surveyed bottom at that spot — one band per RTOFS model level. The outlined stretch is where Cusk's temperature band (37–54°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
Bait pinned to rough rocky bottom in the deep basins — slow, stubborn, and strictly a hard-bottom fish.

"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 30-fathom lane whose seabed temperature sits inside this species' band. It is water, not a sighting report.
