| The spring trap-netting portion of the survey was conducted on April 21 and 22. The results of the trap
netting revealed an excellent channel catfish population with 297 being collected during the two-day
survey. Eighty-one channel catfish were 20 inches long or longer with the largest being 32 inches long
and approximately 14 pounds. The catch rate of channel catfish was the second highest recorded in
The black crappie population at Struble Lake was extremely large with a total of 4,915 individuals collected during the survey. The majority of the crappie were between 7 and 8 inches long with the longest being approximately 9.5 inches. While abundant and relatively small the crappies were not necessarily stunted. It is equally probable that their abundance was related to exceptional reproductive success two or three years ago. Growth rates will be determined once scale samples from the fish are aged.
The bluegill and yellow perch populations were relatively small with few quality individuals available. The majority of the bluegill were between 5 and 7 inches long with the longest being approximately 7.5 inches. The majority of the yellow perch collected were between 7 and 9 inches long but individuals up to 13 inches long were collected.
The trap net survey collected an additional 53 walleye for a total of 77 collected during the night electrofishing and trap netting surveys combined. Sixty of the walleye collected were at least 20 inches long with longest walleye being 29 inches long.
