i think francis is passive aggressively doubting my fish
which of course i expect and for good reason 20lbs coho are very rare, but what you have to understand is francis's head comes up to my nipple. Im 6'5". I can palm basketballs with ease. This coho was gigantically footballed.
C'mon, Merg man.... you know I love you, dude.... big manly hands nipples at eye level and all.
BUT....
I was totally OK believing that those were 20+ coho from the pics all by themselves. SERIALLY.... I was sold on the visual alone!
That is.... UNTIL you posted the measurements of 33 x 22. That's when the cogs of doubt started spinning in my head. I have this "3 x 5 picture" thing imprinted in my brain about the relative proportions of a typical thick healthy chinook. Steelhead are built like more lumber.... 2 x 4.
Coho lie somewhere in the middle. Brand new sleek hens aren't much thicker than steelhead. The REALLY nice coho are virtually all bucks. A great big buck will be approaching those typical 3 x 5 chinook proportions. That's a G:L ratio of 0.6
A coho at 33 x 22 is a G:L ratio of 0.66! Preposterous! Precious few chinook are even built like that!
Applying my fNp king formula on the chunky 17# coho I posted as an example....
at 35 inches fork length and assuming 3 x 5 proportions, the CHINOOK formula predicts...
35 x 35 x 35 (0.36) / 740 = 20.86 pounds
It clearly wasn't, so it obviously ain't.
Not trying to take away from the COLOSSAL coho specimens that you posted, Merg... they really ARE a sight to behold... just wanted you to understand where I was coming from with my comments.
