I'd say the one you are pointing at is awfully heavy.

Generally speaking, lenth times girth squared divided by 775 is the standard formula for estimating the live weight of a fish.

Some will bump the divisor up or down a bit based on characteristics of fish in a certain area / or species variation.

The BC Reports calculator seems especially heavy on salmon with a divisor of 650.

I plugged the numbers of the world-record king salmon into ... a fish that weighed 97 + plus when weighed many hours after being caught. It's believed that the fish was probably a tad over 100 pounds when it came aboard.

The calculator that GMan refers to puts Les' fish at over 126 pounds, the one I use at 106 ... certainly much closer to the actual weight.

Lots of formulas out there ... none will be perfect for every fish, but the one I use I think is the most consistent.

By the way, Les Anderson (a relative of Fishgal, must be in the blood) who caught the world-record fish recently passed away ... for a little more info about Les: http://www.adn.com/outdoors/story/3865153p-3888562c.html
