White Perch
White Perch (Morone americana) is a freshwater and saltwater species. The first thing to check: plain silver-green flanks with no distinct stripes on adults — a faint horizontal shading at most. The look-alike to rule out is White Bass: white bass carry distinct dark horizontal stripes and a tooth patch on the tongue; white perch are unstriped and deeper-bodied.

How to identify a White Perch
- Plain silver-green flanks with no distinct stripes on adults — a faint horizontal shading at most.
- A single continuous dorsal profile with the spiny and soft dorsals joined or only slightly notched.
- A deeper, more humpbacked body than white bass, and no teeth on the tongue.
If you would rather not work through a key on a wet deck, photograph the fish and let the app name it — you get the common and the scientific name back, and the record is filed before you release.
Fish it is mistaken for
| Species | How to tell them apart |
|---|---|
| White Bass | White bass carry distinct dark horizontal stripes and a tooth patch on the tongue; white perch are unstriped and deeper-bodied. |
| Striped Bass | Striped bass are far more elongate with seven or eight unbroken black stripes running to the tail. |

Where it lives
Atlantic coast estuaries from the Maritimes to the Carolinas, and landlocked in lakes and reservoirs through the Northeast and Great Lakes. Moves freely between fresh and brackish water.
Temperature
Feeds well from the high 50s through the high 70s °F.
The conditions that matter
White perch are estuarine, so salinity and tide both matter — they run up into fresher water to spawn in spring and drop back with the season. In tidal rivers the bite concentrates on moving water rather than slack. This is exactly the kind of pattern a logbook that records tide stage and salinity per catch exposes quickly.
Global Fishing League records 18 weather and water readings against every catch automatically — tide stage, barometric pressure, water temperature, salinity, dissolved oxygen, chlorophyll, swell, current, moon phase and more, taken at your GPS position at the moment you log the fish. Over a season that turns a hunch about white perch into a pattern you can read.
See every reading recorded with a catch, or the guides to what each reading means.
Size limits, bag limits and seasons
Size limits, bag limits, slot limits and seasons are set by your state wildlife agency — and for many offshore and migratory species by federal regulators — and on many waters they differ from the statewide rule. They also change between seasons. Check the current regulations for the exact water you are fishing before you keep a fish — we do not republish limits here, because a number that is a season out of date is worse than no number.
What the app does do is make your side of it accurate: every catch carries a length measured from the photograph, a GPS position and a timestamp, exportable if you ever need to show your work for a tournament or a record claim. It is also what a Global Fishing League entry is built from — a record that verifies itself, without publishing where you caught the fish.
