What an awesome fish. Congrats and I'm very jealous. I caught a tiger there once but thought it was something else because I didn't know there were tigers in there.
Since we're having a polite conversation about estimating the weight of fish, I'll throw in a couple of things. When I started getting serious about catfishing I did a ton of research on the relationship between length and weight. One of the first things I learned is that everybody and his cousin has a formula, so it amuses me when somebody says this is THE formula. I compared a bunch of them and gave a lot more credence to those established by scientific studies that used terms like "least square means," "algorithm," etc. What I finally realized is that, according to the various formulas, I could estimate the weight of a channel cat by taking the second digit in it's length and adding one pound. In this case the second digit is 5 and adding a pound would put it around 6 pounds. I know this does not necessarily fit for trout. But I will look up the formulas for trout and get myself more informed. And to echo others, that's a dang nice fish, better than I have ever caught.
Okay, so I did a quick search and found a couple of formulas that were slightly different. They estimated the weight for a 25" trout as 5.84 and 6.57 pounds. For what it's worth:
The equation is: weight in pounds = girth2 x length / 800, with both girth and length measured in inches. Wood's equation was first developed with tarpon in mind, but it was quickly adopted by catch-and-release fishermen everywhere, because it's an easy way to provide a ballpark estimate of your fish's weight.
Fish Weight Calculations
The fish weights are calculated with the formulas below. If a fish girth is not specified, the default value Fish Girth = 0.58 × Length is used.
Trout, steelhead, mackerel, snook, redfish, bonefish
Fish Weight = Length × Girth × Girth / 900
Salmon, bass
Fish Weight = Length × Girth × Girth / 800
Walleye
Fish Weight = Length × Length × Length / 3500
Pike, gar
Fish Weight = Length × Length × Length / 2700
Sunfish, bluegill
Fish Weight = Length × Girth × Girth / 1200

The older I get the more I would rather be considered a good man than a good fisherman.
