Spend More Time Fishing the Right Water
Harness the power of CPUE (catch per unit of effort) data to fish lakes that hold more of your target species. CPUE is a value that measures how many fish were caught per unit of effort (gear count, e.g. # of nets) at a specific point in time, and is a representation of the abundance of each species in that lake.
Within the onX Fish App, Fish Species Abundance Insights allows you to easily see and understand fish abundance in lakes. Save time searching for the bodies of water you want to fish and quickly compare the number of fish in one lake to others nearby, as well as against statewide averages for that particular species. Data from fisheries have never before been compiled and visualized in a way that allows anglers to easily sort through potential lakes and quickly decide where to fish based on CPUE.

Fish Better Water, Faster
Having an understanding of how prevalent your target species is within a water body will save you time and money. Don’t waste hours and fuel figuring out which lakes have good numbers of the fish you want to catch. With onX’s Fish Species Abundance Insights, you can skip the legwork and get straight to fishing with confidence by identifying the best possible lakes to fish.

Spend More Time Fishing
Speed up your scouting process and get on the water sooner by having the power of Fish Species Abundance Insights in your hands. Gone are the days of going to a lake blindly to “figure it out.” Use your time more effectively by quickly evaluating the abundance of multiple species compared to similar lakes as well as statewide averages.

FAQs
CPUE stands for Catch Per Unit Effort, a value that measures how many fish were caught per unit of effort (such as the number of nets) at a specific point in time. It represents the abundance of each species in a given lake.
Fish Species Abundance Insights is a feature in the onX Fish App that lets anglers view and compare CPUE data for lakes, helping them quickly identify which waters hold more of their target species.
Open the app, tap a lake on the map or within “Fishing Spots,” select “Fish Species” from the lake’s detail card, and then choose a species to view its CPUE data. The same steps apply on desktop after logging into your account.
The app lets you compare the number of fish in one lake against nearby lakes and statewide averages for a specific species, so you can make informed decisions about where to fish before ever leaving home.
onX Fish is currently live in Minnesota and Wisconsin, with additional states planned for the future.
The normal range is provided by the DNR and varies by species and lake classification. Anglers can use it to understand a lake’s fish abundance relative to similar lakes in the same region.
By showing which lakes hold strong numbers of your target species upfront, the feature eliminates the guesswork of scouting unfamiliar water, saving you hours and fuel in the process.
