Black Crappie
Black Crappie (Pomoxis nigromaculatus) is a freshwater species. The first thing to check: seven or eight spines in the dorsal fin. Count them — this is the definitive separation from white crappie. The look-alike to rule out is White Crappie: white crappie have five or six dorsal spines and their markings form faint vertical bars rather than scattered speckles.

How to identify a Black Crappie
- Seven or eight spines in the dorsal fin. Count them — this is the definitive separation from white crappie.
- Dark speckling scattered irregularly over silver-green flanks, with no organised vertical bars.
- A deep, almost round body, with the dorsal fin base about as long as the distance from the dorsal origin to the eye.
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.

Side-by-side comparisons

Where it lives
Clearer, weedier lakes, reservoirs and river backwaters across most of the United States. Prefers cleaner water than white crappie and holds tighter to weed and brush.
Temperature
Spawns at 58 to 65 °F and feeds well from the mid-50s through the mid-70s. Suspends deep and stays catchable through winter.
The conditions that matter
Crappie suspend, so depth and temperature together tell you more than either alone. The spring move shallow is triggered by water temperature climbing through the high 50s; through summer and winter the school sits at a fairly constant depth and the reliable pattern is dawn and dusk. Logging depth and water temperature per catch turns that into a repeatable plan.
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 black crappie into a pattern you can read.

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exact water you are fishing before you keep a fish — we do not republish limits here, because a number that is a season out of date is worse than no number.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.
