My observations:

The stumpier the fish the smaller the divisor, the snakier the fish, the bigger the divisor.

Chinook: 740
Coho: 750
Steelhead: 775
Pike: 800+

I have seen Alaska dollies that ran the gammut from spent down-runners, to fresh streamlined ocean-bright up-runners, all the way to gluttonous pigs that have been in the river a while feasting on salmon eggs. I've seen some with the body proportions of a really fat king... ususally they will have a couple skeins of sockeye eggs in the belly.

Any of the divisors listed above would work for guesstimating the weight of a dolly (based on length times girth squared over some divisor) depending on time of year and condition of the fish. Just take your pick of which fish your Dolly looks most like.
