Blue marlin (Makaira nigricans)

How a Blue marlin sees your lure

Which lure colour a Blue marlin can actually see, at your depth and in your water. 2 cone types, peak 484 nm. Ranked contrast for 54 colours.

Makaira nigricans

Measured for this species

Cone peaks are direct measurements for this species. The rest of the model — water optics, contrast, detection distance — is still an estimate, and none of it predicts whether a fish will strike. Billfish warm their eyes and brain, which gives them exceptional temporal resolution — they can resolve fast movement far better than most fish. That is a motion advantage, not a colour one, and this model does not represent it.

Spectral sensitivity

Cone peaks λmax Chromophore
Short 440 nm A1
Medium 484 nm A1
Rod 484 nm A1

Rods do the work at dawn, dusk and night — which is when most people fish.
