In Reply to: Breeding Tiger Salamanders posted by Rick Gordon on April 30, 2003 at 12:29:55:
:Hi,
:I was curious as to what methods are being used to breed these.
:I have bred them in the past using lhrh hormones and I was wondering if anyone has had success breeding them naturally.
:I have just ordered six of them and would like to try breeding them without dishing out 200 bucks for the hormones. I think a rain chamber might work, has anyone tried that?
:
The problem is that A.tigrinum breeds naturally in large aggregations at ancestral spawning ponds, in which an excess of males compete for females – this competitive behavior appears to be an essential trigger for spawning. So you're going to need a large group. The next problem is that the males are quite territorial, so you're going to need a huge area to accommodate all the males you need to get the females in the mood – see the problem? Could be done in a huge outdoor enclosure (e.g. a garden) , but this is not likely to happen in a vivarium and there are no authenticated records of non-hormone induced true captive spawning. Shame.
Mike.
