I was just wondering what are the pros and cons of stocking F1`s LMB vs the Pure Florida strain LMB. Anyone have any input or experience?
Well, for us up here, stocking Pure Floridas or F1's might be a problem due to the cold water in the winter....... wink grin
I have seen in the share a lunker program in Texas double digit bass are rejected due to northern Genes. This leads to a theory that the mixed genetics fish in warm climates will still yield very large fish. Will the top end be the same, IE: 20 pound world record, who knows. I believe the northern genes have a tendency to make the fish a little more catchable. This is just my thoughts and I am not considered an expert.
Why not use both ? Pure Flas are much harder to get to bite an artificial bait. The "catachability" problem has been widely discussed here. FWIW keep in mind that Fla males are small so 50% of your population will be small. F-1 males are not as small as Flas.

It really depends on your goals.
Ewest, is there any documentation on the lower water temp limits on Florida and F1 survivability?
Yes a lot on Flas but not so much on F-1s.

Survival and Growth of Northern, Florida, and Reciprocal
FI Hybrid Largemouth Bass in Central Illinois
DAVID P. PHILIPP AND GREGORY S. WHirr1
Center for Aquatic Ecology, Illinois Natural History Survey

Abstract.—Stocks of northern largemouth bass Micropterus salmoides salmoides, Florida largemouth
bass M. s. Jloridanus, and both reciprocal F, hybrids were produced in Champaign, Illinois,
with natural spawning techniques. The genetic composition of each of these stocks was confirmed
electrophoretically. Overwinter survival of northern largemouth bass in central Illinois was significantly
greater than that of Florida largemouth bass; the two reciprocal F, hybrids had intermediate
survival. The absolute survival rate of all stocks decreased as the severity of the winter
increased; however, the effects were most dramatic for the Florida subspecies. The northern largemouth
bass also exhibited greater second- and third-year growth than the Florida largemouth bass;
again, the reciprocal F, hybrids were intermediate. Results of this study indicate the potential
negative effects that may arise when Florida largemouth bass or hybrids between it and the northern
subspecies are introduced into waters of the USA and Canada that are within or contiguous to the
native range of the northern subspecies.

Here is a basic overview from the study but there is more not said.

Two subspecies of largemouth bass Micropterus

salmoides, the Florida M. s. floridanus and the northern

M. s. salmoides, were first described by Bailey and

Hubbs (1949). Kassler et al. (2002) proposed divergence

of the two warranted species designation. Philipp

et al. (1983) showed that (1) the native range of the

Florida largemouth bass (FLMB) was restricted to

peninsular Florida; (2) the northern largemouth bass

(NLMB) was native to waters north of Maryland along

the Atlantic coast, and then west to the Mississippi

River; and (3) a hybrid zone existed between the ranges

of the two. The FLMB, NLMB, and their hybrids

interbreed where they coexist (Isely et al. 1987;

Gilliland and Whitaker 1991; Philipp and Whitt 1991).

Physiological and ecological differences among

FLMB, NLMB, and their hybrids have been documented.

For example, they exhibited different critical

and chronic thermal maxima (Fields et al. 1987) and

different mortality rates when held at low temperatures

(Carmichael et al. 1988). In addition, FLMB and

NLMB differ in the timing of spawning, growth rate,

reproductive success, and survival (Isely et al. 1987;

Gilliland and Whitaker 1991; Philipp and Whitt 1991).

Performance differs among endemic units within the

historic range of FLMB and NLMB. For example,

growth and survival differed between progeny of

parents from different drainages in Illinois (Philipp

and Claussen 1995). Similarly, swimming performance

differed between Illinois and Wisconsin populations of

bass (Cooke et al. 2001). Lastly, the survival, growth,

and reproductive success of the local stock were higher

than those of the nonlocal stock when comparing

performance among Wisconsin, Illinois, Texas, and

Florida populations at each locale (Philipp et al. 2002).
My goal is to be able to go out and catch a couple of nice chunky bass ( 3- 4lbs) once in awhile and have the chance of a trophy bass. A trophy in my eyes is a bass 8 lbs or bigger.
Then given your location I would use a few of each one Flas , F-1s and northerns.
Thanks ewest, and I agree with you.
Thank you very much for the help guys!
You may also consider Overton's Texas Legacy Bass (came from the Camelot Bell bass).
Heck all they do is eat and grow, who wants that...... Actually very nice looking Legs (Legasy)
well my thinking is i`ll stock my initial bass in from the hatchery, and later on during my trips fishing if I catch a Big female I would add her to the pond for new genes and to have a chance to grow bigger bass
Well transplanting bigger bass don't work real well. A couple of things to consider when you do, do this.

1. Bigger bass don't like change into a different environment and they will most likely die.

2. Said bass you put in there needs a certain size class bait fish to eat to survive and thrive!

You cant just throw a 4 pound bass in a pond that does not have adequate food for said 4 pound bass...

IMO you would be better off growing your bass all together at the same time....

One other thing I have learned the hard way. Any small change to your pond you may think is small and not that big of a deal can come back HARD on you and mess your pond up... I'll I'm saying is be careful when you start throwing that change word around its a pendulum you cant stop once you start it...

Good Luck

On a side not I have FL strain bass in my pond and I know I have some lunkers from catching them in the last couple of years and they were 4 pounds then, but haven't seen them again... When they do bite it's game on, but knowing what I know now I would have tried harder to find F1's what fun are big ole bass when you cant catch em... lol

RC
Very true I was watching a video on the guys who raise the tiger bass which is just a brand name for there F1 and the where saying you don't really have to worry about genetics he was saying you have a 80% 20% slope. You will have 80% that will still carry the F1 traits and 10% that will be more northern and 10% that will be more FL strain
