Hello,

My name is Clint. I am the head reptile keeper at the Gladys Porter Zoo. We currently have 3.2 L. stenophrys. I really want to breed them this year. Any advice you can give me would be greatly appreciated!

Thanks,
Clint Guadiana

I am looking for anything that can help me breed them. For example should I have the males combat, breed them on exhibit or off, what time of year should I put them together etc.

Thanks

Hi, I don´t keep them so I can´t help you but you can try write to Dean Ripa and ask him. If you want I can write you his e-mail address.

Hello, I don´t keep this ones but have you ever tryed something, coolthem down, increase humidity and food disponobility??
There is a guy from Peru you can find him here his name is Walter Silva and he breds L. muta so maybe he can help you.
Good Luck

Clint, im surprise you are asking these question's as with out Collets (head keeper)@GPZ. help i would have never bred Lachesis Melanocephala, it was my male Lachesis Stenophrys that produced the ones you are holding now at Gladys Porter Zoo and Collet was responsible for they're reproduction.
Clint i can not recall a finer or more educated person in this matter than Collet.

Hi Clint,
here in Germany stenophrys is the most breeded (or the only breeded ) Lachesis Species, there is an Article about breeding in a German Herpetologycal Periodical, but unfortunely in german language! If you intressed, maby I can help you! Let me know!

Yes JH,
I know only this one. Maby the are others???

Hi Clint:

Send me your email, I have the paper of the breeding of lachesis (De Sousa, 2007).

My email is w_silva01@yahoo.com

Greetings from Incas´land

Best regards ,

Albert j. Montejo / Zoobotanicals

Albert, please, can you give us something concret please.....
I think a report like that don't help us anymore....... (sorry)

Jean -Henri, i can not, this is one page of ten (pic's inc.) in a confidential report on zoological record keeping, property of ISIS / ARKS and GLADYS PORTER ZOO im providing this to Clint Guadiana to help anwser his question .

* jean-henri , im providing Venomland members a glimpse on professional herpetoculture, maybe this should have been sent to Clint , VIA a PM.

* jean -henri, Clint Guadiana, with permission from GLADYS PORTER ZOO's CEO, President or Head Curator can with sufficient notice easily pull these ISIS /ARKS files and records and write a report on this significant effort and collaboration, on the conservation issue and captive breeding of The Central American Bushmaster, Lachesis stenophrys, for the benefit of Venomland forum members.

Best regards,

Albert.



Addtl: in some future article , if venomland members are interested, ill report on other captive breeding projects involving the Lachesis group at Zoobotanicals.

NECROPSY REPORT

Necropsy Number: 94-08-116

Date of Death : 27 Aug 94

Date of Necropsy : 02 Sep 94

Common Name: Bushmaster

Scientific Name : ???? Lachesis muta stenophrys

Identification: 5700 DOB ???? 27 Aug 94 Sex: M Weight: 32 g
Other ID: DOA ???? 27 Aug 94 Lenghth: 37 cm/ 33cm

Classification: Reptile

Location in Zoo: Herpetarium


History: From a clutch of 13 eggs of which 8 were viable, 4 died in the shell, 2 remain alive,
and 2 died post hatching ; this is one of the 2 which died post hatching.


Antemortem Diagnostic Test Performed:

Hematology
Radiology-
Cytology-
Bacteriology-
Virology-
Parasitology-
Urinalysis-
Toxicology-

Prosector: MWF

Gross Diagnosis: No gross lesions

Final Diagnosis: Acute bacterial enteritis


ISIS Codes: 20 F, 21 A 22 G B


Comments : only cursory necropsy performed, entire "pluck" placed in 10% formalin for histopathology; sex determination important due to incubation temperature study.

TVMDL. Comments: no gonad recovered ; gonadal ridge is imbedded in fat bodies and fascia ( 1/2 between kidneys and stomach) and sex needs to be determined histologically. A system needs to be devoloped for reliable gonad recovery and histological sex determination in embryonic and hatchling snakes (TVMDL # C94249117).


Based on all materials submitted ( hatchlings, yolk remaing from live hatches, and remaing clutch) , bacterial and fungal contamination of the clutch has occurred.


Best Regards

Albert.

Peter , these statements were hand typed not copied , these are the reports from my breeding loan of Lachesis stenophrys at GLADYS PORTER ZOO , with ISIS ARKS # for Clint Guadiana to verify .

The rest is confidential and maybe even this that i typed is confidential you will not find this information anywhere on the internet to copy .

Now, it's in , Clints Guadiana hands, to write a report on this THE GLADYS PORTER ZOO SIGNIFICANT EFFORT for CONSERVATION , i gave him all i can of my collaboration and personal records .

No worries my history goes back to at least 1989.

* Peter soon i will write a breeding article on Lachesis , Bothriechis and Bothriopsis im getting it together with references and i want to add pictures .

Thank you , for looking at my article on , Clint's Thread.


August , 8, 1989

To whom it may concern:

On 8/8/89, I recieved the following preserved snakes from Albert J. Montejo:


3 Bothrops nummifera
1.Bothrops nummifera
1.Bothrops nigroviridis subadult
1.Bothrops schellegi subadult
4.Bothrops nasuta
4.Bothrops lateralis; 3 adult, 1 juvenile

These speciemens will be delivered to Jack Gaskin, DVM Phd, c/o Dept Infectious diseases,
College of Veterinary Medicine, University of Florida, Gainesville , Florida , 32610.

Tissues of the animals will be utilized for viral recovery, Disposal of the bodies will be by cremation unless other wise notified .

Information will be shared with the University of Costa Rica and Albert J. Montejo to determine the cause of death of many pit-vipers in the collection of Instituto Clodomiro Picado,

Sincerely ,

Kevin Wright, DVM.


Addtl: This specimens helped lead to the discovery of the Paramyxo virus .

Unbelievable, you continue with statements lacking any reference to the topic started by Clint Guadiana here.
What the hell have some examinations of specimens of completely other taxa to deal with breeding of Lachesis stenophrys?

and please note, Mr. Montejo:
if you would write "these specimens helped lead to more knowledge or to the discovery of new serotypes of PMV, i would accept it.
But "leading to the discovery of the Paramyxo Virus" generally is just wrong.

Ophidian Paramyxovirus has first been isolated at a Swiss pharmaceutical facility in 1972 from a specimen of Bothrops atrox and has therefore been common named Fer de Lance-Virus.
See Fölsch & Leloup (1976), and Clark et al. (1979).

We're all looking forward for that, hoping you will be too busy with it to do additional senseless postings in the meantime.

Peter Zürcher

You got me ! 100% correct... i left out Ophidian Paramyxo Viruses, in the collection of Instituto Clodomiro Picado and the Dallas Zoo .

Peter, whos Venomland - article/thread /name should i use as an blueprint to how an article of captive breeding or care sheet should be written for an international forum such as Venomland .

i want to be exactly correct.

Thanks for the correction !

Albert.

Clint, as You sure realized, Albert is a so called "forum troll" (suspect - he is not guilty until proved guilty, but he heavily works on proving it again and again).

Grrrrrrrrrr SHIT anybody !
Clint just ask for information in breeding, and you talk about too diferents things!
It the same as each time Albert replay to a post and we all know each time that Peter and Guenter have some hard replic !
I'm not an moderator or administrator but every body here have not the rocket science, also Peter and more Guenter (with snakes) !
why every time Albert mail, you steer against him on a subject that is more, has nothing to do?
Your stories of "who is telling the truth or not, " we give a damn!

Had a bad day, Jean-Henri?

and @ all

back to topic!
If someone has to tell us important facts referring to the breeding of Lachesis stenophrys, he should feel free to post it here.

best regards
Peter

Well Jean, if You read the thread carefully, You'll realize who started to write "about different things".

If You like it or not Jean - I'll post my opinion where and when I want (always trying to keep in touch with the forum rules of course). By the way - Your words

Besides that I did not know that only "rocket scientists" may post here ...

Guenter, our divergences/ differents of opinion are resolved on Pm.
I can also post like you do every Pm i send to you, but i think it's not the right way.....and he can take some time........
So, like said Peter, back to the topic now! Thanks!

I had a pair of stenophrys x melanocephala from Dean ripa!
I did like in most tropical speices
First I separated the male from the female!
I raised the humidity to 80-90% and lowerd the temp about 5-7 degrees celcius, for ca 2 months, then I raised the temp and gradually lowerd the humidity for cpl weeks, and after the femal shedded the skin I introduced the male and after about 24 hrs they mated!
I got 9 eggs and 7 hatched.
