How can I estimate the weight of a fish that was caught and released?

You will need to have the length and girth of the fish to calculate an estimate. This formula works for all fish, although the example is for largemouth bass. To get weight in pounds, square the girth in inches (girth multiplied by itself) then multiply this times the length in inches. Divide this product by 800.

For example, we can use one of the recent ShareLunker bass. The girth was 20.25 inches and the length was 26 inches. First, take 20.25 x 20.25 to get 410.06. Multiply this times 26 to get 10,661.6. Divide this by 800 to get 13.33 pounds.
