Paris -
A well educated guess tells me those animals are close to 3 feet long (maybe a bit less), and depending on food uptake, that should make them approximately 5 years old. Previous claims of released captives by the 100's have been made before on smaller 2 year animals. Supposedly, that is an anual event - who knows.
It's been a long debated topic if the Chinese truly are having successful breedings. They claim to have been since the early 1980's, but no substantial proof can really be presented, and no actual techniques are shared - mainly having to do with how they use the hormones, and exactly how successful the hormones are.
This article and pictures to me doesn't necessarily prove much, but it does show that something is happening, and obviously some people do care - that says quite a bit. Still seems there is a large hurdle to jump before any of these things become concrete.
Either way, thanks for the heads up on the pictures/article!
