Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.

Black bullhead are by far the most common species found in Langdon lake. Their population is considered high for lake class 38, and they are of above average weight. Green sunfish were also found to be very abundant, but are mainly 3.5 to 5 inches in length. Bluegill numbers are average for this lake class. Of 79 fish measured, only 17 were longer than 6 inches, and none were sampled above 8 inches. Hybrid sunfish and pumpkinseed sunfish were captured in average numbers. The most common sizes sampled were between 4 and 6 inches in length. Both brown and yellow bullheads were sampled in average numbers for this lake class. Their average sizes were 9 and 10 inches respectively in both gear types. Only one creek chub and one black crappie were captured during the survey. The black crappie was 9.2 inches long and age three.
