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 naturally pinched to the width of the measuring board.
Each fish must be entered only once. Fish should be entered as soon as possible after catching and catches must be recorded at the fishing site.
The nose of the fish must be at the start or zero mark on all measuring devices.
The entry photo must be taken from a birds-eye view looking down on the fish.
The mouth is allowed to be open, closed, or anywhere in between, so long as the fish meets the other above requirements.
All fish must be measured with the right side down.
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.Gripper tools will be allowed.
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 entry on a homemade bumpboard, these rules must be followed:
The measurement rules are the same as above.
You must provide a photo to the organizer of the empty board to verify proof of measurement accuracy, which includes a measuring tape alongside the bumpboard measurements for verification. This photo must be sent to [email protected].
Homemade bumpboards must have a solid edge or "bump" for the fish to be set against and it must line up with the 0 mark on the tape.
Unverified boards will NOT be accepted
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*
If you measure your fish using a measure net, your catches will not qualify for length-based prizes (eg. longest, shortest, and hidden length), as an accurate measurement can not be read in the photo. The catches will still count towards most fish released, most fish entered, and best release video prizes.
Soft fabric or flexible measuring tapes will not be allowed for use.
Sliding/Expandable Bump boards will be allowed if it can be shown in the length submission photo that the board is fully extended)
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 2.5 cm or 0.78 inch. The entry may also be rejected.
Fish will be approved for length only to the last physical mark crossed. Event organizers reserve the right to adjust entries.
Event organizers reserve the right to adjust entries. They also have the right to ask for a picture sent to them of your measuring device.
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.
During the entry process, a second photo, called the Hero Shot, consisting of the angler holding the fish, will be prompted in the entry procedure and is optional but encouraged for this event.
A third option you will be prompted for is a video of the release of your fish and this is also optional but encouraged for this event and there are prizes for release videos that show good handling practices (see Section 4).
A fourth option you will be prompted for is a photo of the lure used to catch your fish, and is also optional but prizes will be awarded for lures submitted (see Section 4).

“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 a 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, Sean Simmons, directly by email ([email protected]).
