Calculating Fish Weight

One of the biggest question marks in the art of catch and release, is trying to determine how much that nice fish that you just released weighed. Below is some info I picked up off the net, explaining how to approximate a fish's weight.

Thankfully, being of the "old" days, the formula works with pounds and ounces as opposed to metric measurements. By gently taking some simple measurements of the fish before it is released and employing the formula below, you can know how much the fish weighed.

A simple conversion from pounds to kilos is 1lb = 0.455 kg

The Formula:

    ((Girth x Girth) x Length) / 800 = weight in pounds

    (Girth and Length are in Inches)


    If the fish�s girth is 15 inches and its length is 29 inches, the formula would be used as follows:

      15 x 15 x 29, divided by 800 = 8.16 pounds

    Then the ".16" or "16/100" is converted to ounces (multiply by 16)

      .16 x 16 = 2.56 or 3 ounces

    So this fish is 8 pounds 3 ounces
