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!
Example: A 30-inch striped bass weighs approximately 12 pounds (30" x 30" x 30")/2,200 = 12.3 pounds.
