2. Catch Reporting Rules
-
Eligible species include only Walleye, Sauger and Saugeye. Catch and release is suggested but not mandatory if the regulations allow for harvest in the entry location.
-
In order for each catch to qualify, a photograph of the fish on a measuring device must be taken using the MyCatch app (ie. photos cannot be uploaded from a photo gallery or other source).
-
All contestants must have GPS/location services enabled on your cell phone for their catches to qualify. Your location data will be protected. For more information, see details below.
-
This is a total length measurement event, not fork length. The total length of a fish is measured from the tip of the nose or jaw to the tip of the tail (see picture below). The tail can be pinched to the width of the measuring board.

-
The nose of the fish must be at the start or zero mark on all measuring devices.
-
Fish will be approved for length only to the last physical mark crossed. Event organizers reserve the right to adjust entries.
-
The photo must be taken from a birds-eye view looking down on the fish.
-
All fish must be measured with the right side down.
-
If you measure your fish entry on a commercially produced bumpboard, these rules must be followed:
-
The nose of the fish must be visibly touching the bump end of the board;
-
The fish must be placed on top of the board;
-
The entire fish showing the head and tail must be visible in the measurement photo. We must also see past the head and tail in the photo.
-
Expandable (sliding) bump boards may not be allowed if the fish passes the expandable section.
-
If you measure your fish using a tape measure, these rules must be followed:
-
The fish nose and the start of the tape must be aligned by placing both against a solid edge;
-
The fish's nose must be aligned with the zero mark on the tape;
-
The tape measure must be beside the fish, not on top of the fish or covering it in a way that obscures the measurements;
-
The entire fish showing the head and tail and past the tail must be visible in the measurement photo.
-
*Rapala roll out tapes will be treated as a tape measure*
-
Soft fabric or flexible measuring tapes will not be allowed for use.
-
If an entry submission comes in where a measuring rule is not followed, the fish may still be approved but a length penalty will be applied. The penalty will apply to the observable length of the fish at the discretion of the Organizer. The set penalty amount will be 1 inch. The entry may also be rejected.
-
The mouth is allowed to be open, closed, or anywhere in between, so long as the fish meets the other above requirements
-
There are to be no fingers placed in the gills or mouth of the fish. Any fingers in the gills or mouth of the fish will disqualify that fish. This rule applies to the Measurement photo only.
-
A second photo, often called the Hero Shot, is to be used as a hero shot and is optional for this event.
-
A third option is a live video release of the fish and is optional for this event. NEW FOR THIS YEAR there are random draw prizes for videos submitted showing the live release of a fish. This must show the fish swimming away under its own power.
-
The app will work even when out of cell range, however for catches to qualify they must be synced with Angler’s Atlas server. To learn how to submit a catch into the event you can watch this MyCatch video for more information: https://www.youtube.com/watch?v=fS65wMakQHA
-
Our Catch Approval Team reviews and judges all fish. Once a submission has been approved, it will appear on the appropriate leaderboard(s). Entries will not show up immediately after you sync them.

6. Data Privacy and Fisheries Research
“Secret Fishing Spots Stay Secret” — This is our primary commitment to anglers who report their catches through MyCatch. So what does this mean in practice?
-
Angler’s Atlas does not release MyCatch GPS data to the public. It is treated as confidential and is provided to fisheries researchers under strict conditions.
-
Every research team we work with must sign a data sharing agreement that sets the terms of use for the data.
-
Data is anonymized before it is provided to the researcher.
-
Researchers agree not to share the data with anyone else.
-
Researchers cannot use the data for any purpose other than the research specified in the agreement.
-
Exact location data cannot be published as part of the scientific research. Instead, it has to be generalized to a larger region so the location cannot be reverse engineered.
-
Angler’s Atlas may release data to a law enforcement agency if compelled to do so under court order.
These data privacy rules are designed to protect our angler’s private data, to conserve the fisheries, and to make sure we maintain a trusting relationship with our anglers into the future. If anyone has any questions, please feel free to reach out to Angler’s Atlas President directly by email ([email protected]).
