Dobrogicus breeding time... in autumn??

[rubén]

My dobrogicus community. Good feeding and decrease temperatures this autumn seems to stimulate courtship.

mmmmmm... nice smell

courtship

What's up! I'm laying

Somebody has seen females here down?

Hola Rubén!

I also observe the courtship of T. dobrogicus. And in their aquarium I have counted 27 eggs!
All my friends who keep T. dobrogicus in Moscow and from other cities of Russia communicate to me about the courtship and eggs!

Saludos!

Nice photos...Nice looking animals.

Hi Alexander!

The problem that I see is the high proportion of unfertile eggs and chromosomic problems on this species. We will see how many eggs can we save...

 

[ali]

I don't think it is only dobrogicus. I have noticed my taricha's amplexing as well.

 

[rubén]

Interesting... I thought this chromosomal abnormality ( which results in the death of 50% of all eggs ) affected only to the big size Triturus ( cristatus, marmoratus, etc... )

Interesting enough, my dobrogicus females have become aquatic and their tail have broadened. the are in full breeding form in lieu of a male. The temperatures of the room in which they are kept in remains 13 degrees. They probably were stimulated by the low temperature and light periods.

T dobrogicus also suffer the 50% egg loss. I had a lot of eggs with my females but few failed in development. In my case only a few larvae made it to metamorphosis.

Hi Rubén!
We have similar problems: our Triturus dobrogicus dobrogicus (3-4 generation) are descendant of several newts from the delta of Danube (Ukraine). Today I have seen that 70-80% of eggs in my aquarium died. But summer eggs and larvae had big survival percentage (80-90%).

Excuse me please, this is personal message:

Según el foro para acuariumistas/terrariumistas hispanohablantes, tus compatriotas mantienen Triturus dobrogicus también:

Creo que para la evitación de los problemas genéticos hay que ponerte en contacto con ellos...

Beautiful animals, Ruben!

There are a number of species that will begin courtship and egg laying in the fall, if conditions are right. I am already getting eggs from M. alpestris, L. boscai, and C. ensicauda. Only the ensicauda are laying fertile eggs, the others are infertile so far.

How do you keep your anacharis so green and lush?

Great pics and stuff man! Can you post one of the whole enclosure?

Dan__Anacharis are robust plants; at least, those from the ponds ( what I keep ) use to "explode" when feels heat and artificial illumination. I think I don't make nothing special; good illumination, good soil... temperature also would be important.

Hi Ruben and all,

in my breeding group of T. d. macrosomus it is common to spawn twice a year, in March and October. The fertility is much better in spring and I suppose the fall courtshipping is not natural but from captive conditions which are similar in fall and spring. There should be a trigger missing which indicates the animals that it is fall season and not breeding season.

I don´t observe this in the other crested newts I keep (mostly all which are in the hobby).

Greetings,
Steffen

Very nice tank. Thats basically what I want with my anacharis, a little type of 'jungle' spot. It appears I may have a more tropical anacharis so its not working out like I hoped.

Hi Stefan__I observed autumn spawns in T. karelinii also, when I kept this species in the past. But, well, to be honest not so accentuated as in dobrogicus maybe.

Dan__I don't know... my Anacharis are in a margin of 19-23 ºc, because this autumn is being quite mild. Anyway the secret maybe is the substrate and the light ( special for plants )

Wow great pics!!!
i never get tired of seeing dobrogicus pics...
Probably one of the most stunning and interesting species.
Congrats on the animals.
Btw...how did it go?? did you get eggs?

 

[chris]
