Physical Fish Simulation

Why the fish you see is the same individual you can catch.

Quick answer: Every fish has a physical representation and is individually simulated; fishing targets visible creatures rather than resolving only through random chance.

Official evidence

ION LANDS explicitly says fishing is not based on random chance. Hundreds of fish can appear simultaneously, and the specific salmon caught is the same physical fish that was visible in the water moments before.

How to use this information

A mechanic test should track one fish from sighting through bait response to capture. Record camera angle, water location, bait, distance and time, then repeat to separate player targeting from autonomous movement.

What the confirmed data means

Visible simulation means positioning and shoal behavior may matter more than an unseen percentage roll. It also makes screenshots and short route videos valuable evidence for a guide once exact controls are known.

Publication boundary

The statement does not remove every random variable from the wider system. Bite timing, species distribution and rare spawns have not been documented.
