How do you measure the weight of a fish?


  1. Weight of a fat-bodied fish. (bass, salmon) (length x girth x girth)/800.
  2. Weight of a slender fish. (trout, northern pike) (length x girth x girth)/900.
  3. Example: If a fish is 20 inches long and has a 12–inch girth, its estimated weight is. (20 x 12 x 12)/900. 2,880/900=3.2 pounds.
