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.
ALTHOUGH BLACK CRAPPIE WERE NOT TAKEN DURING THE SURVEY, THE OWNER OF CAMP SECLUSION SAID IT WAS AN EXCELLENT WINTER AND SUMMER CRAPPIE FISHING LAKE. ANY WALLEYE THAT ARE CAUGHT ARE LARGE.THE FISH POPULATION LOOKS VERY SIMILAR TO WHAT WAS FOUND IN THE 1973 SURVEY WITH THE BULK OF THE POPULATION MADE UP OF CENTRARCHIDS AND TULLIBEE AND THE REST COMPRISED OF NORTHERN PIKE, YELLOW PERCH, BULLHEADS AND BOWFIN. NET CATCHES AND AGE AND GROWTH ANALYSIS SHOW THAT THE BLUEGILL POPULATION IS ABUNDANT AND IS MADE UP OF RELATIVELY SMALL, SLOW-GROWING FISH. NUMBER AND GROWTH OF LARGEMOUTH BASS IS GOOD. NORTHERN PIKE REMAIN LOW IN NUMBERS AS COMPARED TO OTHER LAKES IN THE AREA. ALL YEAR CLASSES ARE PRESENT AND GROWTH APPEARS TO BE GOOD TO EXCELLENT.ONE LONGEAR SUNFISH WAS CAPTURED IN A TRAPNET AND THE IDENTIFICATION WAS CONFIRMED BY DR. JAMES UNDERHILLS, UNIVERSITY OF MINNESOTA.
