Built from mechanisms
Light attenuation, density, hydrodynamics, and known behaviour—not “secret colours.”
Behavioural simulation laboratory
Stop guessing.
Think like the fish.
Build a lure. Put it underwater. See what the fish sees—and learn exactly why it strikes or refuses.
Physics-ledSpectral opticsOpen assumptions
The simulation stack
One question. Three ways in.
Every tool isolates a different part of the strike—from photons in the water to the final decision.

Fish Vision
See what survives the trip down—not what the lure looked like in your hand.

The Tank
Assemble real materials. Test buoyancy, balance, drag, and action.

The Fish
Run the predation sequence. A refusal comes with a reason.
Present your lure →The useful outcome
“No” tells you more than “yes.”
A fish refusing your lure is not a dead end. The model traces the failure to a specific stage, shows the evidence, and gives you something testable to change.

DETECT ✓APPROACH ✓TRACK ×COMMIT
Tracked to 1.4 metres, then refused.
Action too uniform. No acceleration, deflection, or pause crossed the reaction-trigger threshold.
NEXT TEST Add an erratic cadence or contact event.
No magic. No folklore.
A model should show its work.
Wrong in public
Assumptions, coefficients, confidence, and failure modes are named where you can inspect them.
Made to be tested
Change one variable, run it again, and take a better hypothesis back to the water.

Put your assumptions underwater.
Start with any lure. Change the depth, clarity, and species. See what is actually left.
