Salmometer

How Big Was That Fish?

The Atlantic Salmon Federation has devised a length/weight table, called a Salmometer. It enables the angler to estimate the weight of the salmon once its length has been measured. (In catch-and-release angling it is not advisable to weigh the fish; there is too great a danger of fatally injuring the fish.)

The length of the fish must be measured from the tip of the nose to the fork of the tail. Look up the length in the Salmometer, given in both inches and centimetres, to determine the weight, in pounds and kilograms, immediately to the right.

Length and weight data from different river systems were used to prepare the Salmometer. Salmon from other rivers may differ somewhat in shape, so the precise weight of your salmon may be slightly higher or lower than the figure given in the Salmometer
