How a Yellowfin tuna sees your lure
Which lure colour a Yellowfin tuna can actually see, at your depth and in your water. 2 cone types, peak 483 nm. Ranked contrast for 54 colours.
Thunnus albacares
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.
Spectral sensitivity
| Cone peaks | λmax | Chromophore |
|---|---|---|
| Short | 426 nm | A1 |
| Medium | 483 nm | A1 |
| Rod | 484 nm | A1 |
Rods do the work at dawn, dusk and night — which is when most people fish.
