Gambusia

[helterskelter]

Sure they was at the last BLA auction. Duncan may remember or ever have them

Yes your correct about them laying eggs, their in the family Poeciliidae and the males fertalises in the same as all other livebearers, how ever several days later the female then lays individual eggs on aquatic plants or mops.

They weren't at the BLA auction, I have never seen them.

Oh sure i saw some somewhere and would of though it was the BLA auction

Oh well

G. geiseri (Largesprings Gambusia) extinct? Where is this information? Environmental Biology of Fishes 64: 428, 2002 and New Species of Gambusia (Cyprinodontiformes: Poeciliidae) from Del Rio, Texas Gary P. Garrett; Robert J. Edwards Copeia, Vol. 2003, No. 4. (Dec. 4, 2003), pp. 783-788. States they are still present and the State of Texas has no protection granted for them. Do you mean Gambusia georgei?

Hi Sean,

You are quite right, I did mean Gambusia georgei; I understand there will be trips to collect geiseri at the next ALA convention in Texas; which would be completely futile if they were extinct

Thanks for correcting me.

Incidentally, see the attached for a checklist of freshwater species of Texas; even though it is a bit out of date: -

" I understand there will be trips to collect geiseri at the next ALA convention in Texas; which would be completely futile if they were extinct"

That is a very cool idea for a collecting trip. However since the waters there were G. geiseri occupy are the same for Gambusia georgei in the San Marcos river I would be a bit careful since even collecting in the same river could be construde as interfering/disturbing a protected animal placed on the Endangered list. Even thought it may already be extinct.

Three species of Gambusia occur sympatrically in the upper San Marcos River. But careful indentification can distinquish between affinis and geiseri.

Dunchp are you going to the ALA conv. in Texas? If so I would love to meet and talk with another Gambusia person. I live in Dallas so it is a nice short trip to San An.

Hi Sean, yes I am going to the convention next year. I am sure that there is plans to collect geiseri, but I may be getting confused again.

It will be good to meet you too.

I will check it out and let you know.
