Copper Rockfish

Sebastes caurinus. Prime water reaches San Francisco in California right now (51°F on the bottom). Fish it 49–187 ft down — that is where 56–53°F water sits off San Francisco.

The strip is the water itself, coloured by temperature from the surface down to the 187 ft surveyed bottom at that spot — one band per RTOFS model level. The outlined stretch is where Copper Rockfish's temperature band (46–63°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 or jigs right in the rock — a homebody that holds tight to one piece of structure.

"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.
