Tournament Host/Director

By registering for the contest, all participants agree that they are executing an agreement to abide by all contest rules. The interpretation and enforcement of the rules is at the sole discretion of the tournament director. The tournament director may change rules or impose sanctions as they deem appropriate including but not limited to: disqualifications, forfeiture of prizes, and prohibition from competing in future contests. All decisions made by the tournament director are final.

Inclement Weather and/or Unsafe Conditions

If weather or ice conditions are questionable, please use caution. Keep mobile phones on throughout the contest in order to receive communications from the contest officials.

FishDonkey App

All registration and payment must be completed using the app. The FishDonkey App will be used to record, measure, and document fish and then upon submission, the app will place the fish on the live leaderboard. The leaderboard will be updated throughout the day as fish are submitted by contest participants. All entries will be considered unofficial until verified by contest judges.

Measuring & Submitting Fish

  • All of the photographs must be taken through the FishDonkey app and measurements must be on a valid measuring board, device, or tape of some kind.
  • Take at least two photos of your catch: one photo of the person holding the fish and a second one of the fish on the measuring board. Also, include a video of no more than 30 seconds for all released fish.
  • You must close the fish’s mouth and touch the tip (nose) of the fish to the lip on the left side of the measuring board (The belly will be facing you). The fish tail may or may not be squeezed to determine length, depending on the specific rules of your tournament director. Take the photo in a horizontal position, so that both the fish nose, which is touching the board, and the tail, which is indicating the measurement, are clearly depicted.
  • If there are two fishermen present, then both fishermen should agree on the length. If the fish tail is touching the graduation line on the board then that is the exact measurement for that fish. If the fish tail crosses the graduation line, then the measurement can be rounded up to the next highest 1/4 inch.
  • All Participants must have their fish submitted before the deadline marking the end of the contest.

Ties and Tiebreakers

The tournament director will consider options for determining a tie 1) the time of entry of the submitted fish and/or 2) the photographs of the submitted fish and/or 3) the next largest fish submitted by that fisherman. It is at the tournament director’s discretion as to which method to use. If a winner cannot be determined, then a tie could result in shared prizes. E.g. in the event of a tie for the largest fish, the 1st and 2nd place prize winnings might be combined and shared equally between the two participants.


Leaderboards will be updated throughout the contest. The app will update the leaderboard throughout the month as fish are submitted. All entries are unofficial until verified by contest judges. At the end of the contest, the top entries from the leaderboard will have their submitted fish verified by a judge. The judges shall have the right to verify that fish submissions are accurate and that they were legally caught. The decision of the judge is final.

Measuring Boards

Measuring boards should be used to measure all fish. Measuring boards are subject to inspection and approval by the tournament director. Failure to use a proper measuring board, such as a rigid board with clear numbers and a nose bump to help measure the fish, could result in a length penalty.
