For those who don't have a digital scale in the field but want to get a realistic estimate of salmon weight this link is pretty useful: http://www.piscatorialpursuits.com/resourcecenter/weightcalculator.htm Measure your salmon's length from the tip of the snout to the fork in the tail, then measure the girth just in front of the dorsal fin. Write it down in your fish log and run the numbers. A true 10 pound salmon would be about 29" in length and 16.5" in girth. A typical 5 pound Puget Sound silver would be about 25" in length and 13" in girth. Add 2 inches to that girth and you have a chubby 7 pounder.
