Hey everyone, i was reading the thread about double digit fish and noticed several references to different strains of florida lm. I think f1 was one and maybe one other? Does anyone have a good link on where i can find info on these different strains? I live in central oklahoma and i only hear about florida l.m. in general, no specifics on species. Im just cuious and would like to know more about it.

The are 2 strains of largemouth bass; northern and Florida.
When the 2 pure strains cross breed their off spring is an intergrade of the 2 pure strains called F1.
When the intergrades spawn with pure a pure northern or pure FLMB the F designator changes until the intergrades are spawning with intergrades, each intergrade getting a new F designator, I don't recall how high the F numbers are listed, someone will answer that.
Beyond F1 intergrades there isn't any reason for bass anglers to know unless you are studying these fish.
The reason a pure Florida and F1's do not have wide distribution is their low tolerance to water colder than 45 degrees.

So would a bass in oklahoma not be a pure florida strain? Id guess that many smaller waters around here drop below that at some point during the year meaning there must be some northern strain in them?

You need to check with your Local department of natural resources DNR or whomever is responsible for fisheries management. FLMB are not native outside of Florida and must be transplanted. Oklahoma may be too cold for FLMB unless the water is heated during the winter by a power plant.

PS, Oklahoma state record LMB is 14.14 lbs., consistent with northern strain LMB

I see doing a little google search that OK has acFLMB stocking program started in 2012.

F1 ---> 50/50 %

F2 ---> 25/75 %

F3 ---> 12.5/87.5 %

 

And so on, which each sucessive generation the percentage of hybridazation diminishes when indivuduals are subject to the presence of 100% pure strains. Otherwise, there comes a point where the percentegages stabilize depending upon the original population.

I know when I lived out by Lake Thuderbird they had just stocked some Florida Strain fingerlings that they had in a stock pond by the marina....that was in 1991, so there may be mixed fish there now. Believe there are a few SE lakes that have Florida's stocked in them as well but are probably F1 fish in there as well now too.  Just have to look it up and see where they have stocked them.  Most lake records over 13lb are more then likely home to Florida's and F1's.

It's my understanding that hybrid is made up of 2 different specie, an intergrade is made up of 2 different strains of the same specie.

If the lake had zero northern strain LMB before the pure FLMB was introduced, they will remain pure Florida LMB. The F1 designates the first generation of any animal that intergrades or hybrids.

F1 could apply to a smallmouth and spotted bass hybrid or northern strain LMB and Florida strain LMB.

Hybrid is the mix of two different of anything: two species, two subspecies, two races, two breeds.

 

A hybrid becomes a breed when it´s characteristics are well defined and transmit fully from the parents to the offspring, for example the Brangus breed of cattle: BRA: BRAHMAN breed + ANGUS: Abredeen Angus breed, the percentage expressed in fractions is : 3/8 Brahman, 5/8 Angus, another example St Gertrudis breed : 3/8 Brahman, 5/8 Shorthorn. They have become a breed but they are hybrids of two different breeds and from two different subspecies: Bos primigenius taurus ( european cattle ) and Bos primigenius indicus ( asian cattle )

Raul's right on.  To further clarify....when naming hybrids, it is generally accepted to use the male parent as the first part of the name, and female parent for the second. 
 
Therefore, a "coydog" would come from a coyote male and dog female.  Or, Canis latrans x Canis lupus familiaris, for the scientific type.

 

so are they Florimouth bass or Largida bass?

Here is base level site that brushes on the absolute basics of different bass.

The second is a little technical and dated by about a decade, but should be a fair starting point which discusses stocking the different fish.  I, admittedly, have not read the publication - merely glanced over it.  There are a TON of references at the end, I think surely if this doesn't quench your thirst you should be able to find a few of the references useful.

There are a ton of articles out there which are amazingly informative if you have access through your local library or university.  Or, usually, you can outright buy the articles.

 

 

At the highest level you have three common types of Largemouth Bass.  Largemouth Bass Micropterus salmoides, Florida-Strain Largemouth Bass Microperus salmoides floridanus and their interbred offspring.  A pure LM bred with a pure FLM gives you the "F1" or "F1 Hybrid" the first generation offspring from the two pure strains.  The "Northern" strain is much more tolerant to colder conditions and seemingly more aggressive feeders, whereas while less aggressive and more anlger wary, the Florida strain grows faster and larger. 

 

I hope that helps, and that I didn't get anything wrong in my brief summary.  If I did, I'm sure someone will correct me.
