Striped Marlin

Kajikia audax. Prime water reaches Channel Islands in California right now (70°F at the surface). Fish it around 25 ft down — that is where 71°F water sits off Channel Islands.

The strip is the water itself, coloured by temperature from the surface down to the 597 ft surveyed bottom at that spot — one band per RTOFS model level. The outlined stretch is where Striped Marlin's temperature band (70–84°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

Look for tailers and sleepers on a warm blue break, then bait-and-switch with a live mackerel.

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