Has anyone bred this newt???should it be hibernate to breed?how many eggs are laid?
Thanks a lot

I've bred them in the past, and they are commonly bred overall. I didn't hibernate mine, but it surely would help to drop their temperatures to around 10-15C for a month or so in the winter. At these temps they will stay active and so true hibernation isn't really taking place. A single female can lay up to 400 eggs.

thanks a lot for your message!
according to you, how many efts should I buy to be sure to have a male and a female?

Well, if your plans are to breed them I'd personally get at least 6 efts.

thanks a lot!
which species have you bred?

 

[nimbus2]

European species do make their way to the US through the pet trade occasionally. Also, many species can be legally imported from European keepers. There are many Europeans keeping and breeding European species as well as societies for the keeping/breeding of Caudates, just check out these sites:

In the September 2003 issue of Herpetological Review there is an article on breeding Notophthalmus viridescens through the use of hormone manipulation.
The interesting thing in the article was that they were able to bypass the eft stage by keeping the newts aquatic (5 cm of water with plastic plants or rocks just breaking the surface).
Keeping the efts this way they have been able to get the newts to sexual maturity in 6 months.

They didn't list the area where the newts were collected but as the research was carried out in Canada I would suspect that the subspecies was N. v. viridescens.

Hi,

I am one of the authors here. I was doing a google search of my name and found this! With respect to sexual maturity, the majority of efts did reach sexual majority, but were small in size. They were no bigger than other efts, but were able to mate. They did grow to full adult size, though. The biggest factor, though, was the ready availability of live food.

For your information, the newts came from a farm (I am unsure if it is a pond or facility) in Tennessee.

Even though the last post was back in October, I hope this information helps.
