In the rule “The Big One”, add a subrule named “Last Catch” with the following text:

There is a publicly-tracked Last Catch which contains a date and time, defaulting to the current date and time rounded down to the nearest hour plus 168 hours (7 days).

If the current date and time is on or after the Last Catch, at their earliest convenience the Elder Judge should perform the Last Call, which is an atomic action with the following steps:
* Resolve all pending Fish Identifications in the order they were received
* If the Big One Caught atomic action was performed as a result of the previous step, skip all remaining steps of this atomic action and consider it completed.
* If the Found Fish list is not empty, if there is only one Fishing Contestant whose name appears in the most entries in the Found Fish list, mark that Fishing Contestant as the Hero.
* If the Found Fish list is not empty, if there is more than one Fishing Contestant whose name appears in the most entries in the Found Fish list, among those Fishing Contestants mark the Fishing Contestant whose name appears first in the Found Fish list as the Hero.
* If a Fishing Contestant was marked as the Hero in this instance of this atomic action, perform the Big One Caught atomic action.
* Set the Last Catch to the current date and time, rounded down to the nearest hour, plus 168 hours (7 days).

In the subrule “Trophies”, add the following step just before the last step in the atomic action Big One Caught:

* Set the Last Catch to the current date and time, rounded down to the nearest hour, plus 168 hours (7 days)
