DEEP: How Much Does Your Fish Weigh?

 How Much Does Your Fish Weigh?

Fish can be injured when weighed with portable scales. To estimate the weight
of your fish, simply take a length and girth measurement (in inches),
and use the following formulas. Remember, these are only estimates!

Formula Explanations:

{Measuring Length and Girth}
Length3  = Length x Length
                    x Length

Length2  = Length x Length

Girth2  =  Girth x Girth

Girth is the greatest
distance around the body
A = Length B = Girth
