Here's a picture of a northern strain largemouth that came out of a pond managed by my friend Aaron Klusmire.
For a pure northern strain this is a remarkable fish.
No length or weight?
Oh, I get it! Aaron is only 3' tall???
Standard Length for a 9 lb LMB is 24.7". There are also catch & release standard formulas for calculating length or weight when one parameter is known. Anyone have the formula readily available?
There are 2 one for fish that look long one for fish that look stocky. An average of the 2 seems to work. They both require length and girth measurements. The first is the more commonly recommended method.
Long looking LMB - L X L X G / 1000 ( 1200 ?)
Stocky looking LMB - L X G X G / 800
I will try to find a prior thread on this. Here are 2.

How do you know that this is a pure strain northern. I have pure floridas and pure northerns and even crosses. So how can you tell?
Can Florida crosses live in Nebraska?
Probably unlikely but I'm curious because I thought I read that crosses don't do well up North and the significance of Florida genes decreases dramatically the further North they get.
There is little info on F-1 crosses in colder climates. Flas don't do well in colder climates. I will check some more as it has been a while since the last look.

Responses of Northern, Florida, and Hybrid Largemouth Bass to
Low Temperature and Low Dissolved Oxygen

Low Temperature
Largemouth bass treatment groups that were
cooled slowly and then held at about 2°C for 5 d
demonstrated differing rates of mortality (Figure
1). Mortalities were significantly higher (chi-square)
among Florida fish (48%) than for other strains,
4-5% for F x N fish and nil for N x
F fish. All fish in water that was cooled from 21
to 1°C, held at that temperature briefly, and then
warmed to 21 °C in 90 min survived and fed normally
within 24 h. Feeding behavior was normal
as temperatures dropped to 13°C, fish fed slowly
between 12 and 6°C, and no feeding by any fish
was observed at temperatures below 6°C.

Dissimilarities in response to low-temperature
challenge is expected between fishes whose native
ranges differ latitudinally. Previous studies have
indicated differences in temperature response between
the northern and Florida subspecies of
largemouth bass (Cichra et al. 1980; Guest 1982,
1985)—as well as similarities (Guest 1980). Direct
comparison of the four strains enabled us to show
that both subspecies and their hybrids tolerated
brief exposure to low temperatures, but that survival
after prolonged exposures was better in N x
N and N x F strains than in F x F and F x N
strains (female first). The responses of both hybrids more closely
resembled the N x N than the F x F fish. Strain
contamination (hybridization) could have significantly
affected previous studies and accounted for
the variable results among those studies. Our results
showed clear-cut differences in mortality due
to cold exposure, and we speculate that exposure
to low temperatures might result in additional response
differences among largemouth bass strains.
For instance, after exposure to cold, the strains
may have different responses to a secondary
stressor or to diseases; for example, exposure to
low temperatures has been shown to alter the response
of largemouth bass to net-confinement
stress (Carmichael et al. 1984b).
Aaron also manages a lake that has about a half dozen NE state record saugeye in it. I know because I shocked them up with him last fall. They were fat, beautiful fish.
Wow this is so ironic. Aaron called me yesterday about a project in FLA. I do not know him but enjoyed the conversation. We spoke of Bruce and he told me he has known him for years and now look here a post from 2006 from Bruce about Aaron. Also of interest is that Aaron told me he has been trying some tiger(f1) bass as well. I wish this post was brought up b/f my conversation and I would have asked about this bass.
BTW my new policy is to have less typos in my post. Doubt it will happen but that is the idea. As mentioend in the past F1's do well in KY, if that helps.
We should start a new trivia game.... "The Six Degrees of Bruce Condello."
http://i248.photobucket.com/albums/gg186/tksimmons/035-1.jpgThis is a northern strain LMB that came from one of the lakes Aaron manages that has the saugeye in it too.
How do I post a pic, not the link to it?

I have been noticing a difference.
Who are you, and what have you done with the real Greg Grimes?
Yesterday, while fishing a small pond near my house, I ran into a guy and his daughter who claimed they were the uncle and Goddaughter of this "huge fish guy" in the midwest by the name of Aaron Klusmire. Told him about Pond Boss, he gave me Aaron's phone number, and curiosity got the best of me and I Googled his name. Wouldn't you know, this thread was second only to his website.
