Create a new dynastic rule called Fishing with the following text:

As a Fishing Action, a Fishing Contestant may Cast Their Line (or Cast, for short). When a Fishing Contestant Casts, they gain a number of Catches equal to half the orthogonal distance to the Judge’s Hut from the Sea Chart cell they’re currently in, plus one if they’re in an Ocean cell, plus three if they’re in a Disturbance’s cell.

Create a subrule of that rule called Disturbances with the following text:

There exists a publicly tracked list of Disturbances which should have 3 entries, each one consisting of a non-Shore cell label.

There is an atomic action called Sight Disturbances which only the Elder Judge can perform, and should do so as a Daily Action. It has the following steps:
* A random Disturbance is removed from the list of Disturbances
* A new Disturbance is created in a random non-Shore cell
* Any fishing contestants in that cell are moved to a legal adjacent cell in a random direction, if possible
* With a 50% chance, the preceding three steps are repeated, with the newly created Disturbance not being eligible to be selected in step 1.

While the Elder Judge Sights Disturbances, they are permitted to determine its random values secretly.

If there are ever less than three Disturbances, the Elder Judge can perform the Sight Disturbances action as many times as necessary to bring it up to 3, skipping the first step and ignoring the restriction that it is a Daily Action.
