Hi again everyone, I have been a member for awhile, but have been away for about a year. It seems most of you are doing well. I have a question. I caught a bass about three weeks ago (released it). I didn't have my scale but I took the measurements. They were 25 inches for the length and 22 inches for the girth. I put those numbers in the weight calculator on the bass resource website and it came up with a weight of 11.46 pounds, which I was very pleased with. However, this morning I see the fifteen pounder posted by matt. The link says that the fish was 25.5 inches long and has a girth of 22 inches. That's only a quarter of an inch difference in length than the fish I caught. I found few other site with weight calculators and some come up with a weight of 15.12 pounds while others come up with 11.46 pounds. I even had one that came up with 12.03 pounds I am not doubting the weight of the fish posted by matt, but my question is did my fish weigh 11.46 or 15.12 pounds? :-/ Also, my pastor and I went fishing last Friday, he caught a fish that was 25.5 inches long with a girth of 18.5 inches (also released it). The bass resource scale and some other sites come up with 10.02 pounds but other sites come up with a weight of around 11 pounds. :-/
