Bluegill 9-11 inches
LMB 9 - 11 inches
Average CC were about 28 inches -- started over last May with 5-inchers.
Wow! I'd like to get to a point where I land an 11 inch bluegill and consider it average!
I guess I'll replace my fishing hat with my mathematician's hat. As others have alluded to, we really aren't using averages. Instead, we (at least me) is/are using some statistical hybrid of catching fish -- on hooks -- near a mean or median size.
I'm at the office, so I don't have my fish tracking spreadsheet available. However, I believe I caught about 240 bluegill last season, of which I kept just over 100.
I mainly kept females, and I kept very few that were below 9 inches or over 10 inches. All injured males, and any injured females outside of this slot range were kept.
As I recall, about 70% of the females caught were between 9 and 10 inches. The average of all caught fish was probably below 9 inches due to more 6-8 inchers, than those exceeding 10 inches. I didn't catch a significant number of females that were over 10 inches. I'm guessing that the median size of kept fish was probably close to 9.5 inches.
Most of the males ranged between 9 and 11 inches, with somewhere just over 50% of them between 10 and 10.5 inches. The average size for all males caught was probably around or just below 9 inches, again due to more 6-8 inchers caught than those bigger than 10.5 inches. The median was probably close to 10 inches.
Of the really large BG returned to the water, I also don't know how many times I caught some of them, so that too skews my numbers for large fish. Because of mouth sores, I know that a few of the really big males were caught a number of times over the season (big dumb fish??).
Also, the size accuracy of the larger non-kept bluegill is not as accurate as the kept fish. I try not to touch any fish (with my hands) that will be returned to the water, and I try to take them out of the water for only extremely brief periods. The measurements of those returned to the water are done by comparing marks on my dock posts or by marks on my fishing rod. I try not to let their scales touch anything. So, the measurements are probably plus/minus at least a half inch, maybe more.
To further add to the inaccuracy, I also only keep my statistics in even increments of 1 inch. So a fish that is 9.4 inches gets recorded as 9 inches. A fish that is 9.6 inches gets recorded as 10 inches.
Lots of room for error, but I know that I only need three bluegill to provide a nice meal for my wife and me. When we have company, we estimate 1-1/2 fish needed per person for a decent meal.
Sorry I got so long winded.
