Pollock
Pollachius virens. Prime water reaches Penobscot Bay in New England right now (53°F on the bottom). Fish it 115–210 ft down — that is where 50–43°F water sits off Penobscot Bay.

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 Pollock's temperature band (37–59°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.

"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.
