If you contact me directly, I can give you the references to which my post was referring.
As far as many Asian medicinal practices go, yes, most things can be synthesized; I just do not have a clue as to the importance of G. radiata and Pyxis livers. The post did not refer to Pyxis sp., so I did not include that in the last post. I have spent a third of my adult life in the Asia-Pacific regions, but things such as killing endangered species for food or medicine still baffles me.
I believe that the pictures are from the reserve, since that should be the only captive concentration of those tortoises in Madagascar. Some sensitive breeding programs do not allow visitors, so I would make sure to make liaison with them before wasting a lot of time and money.
From reports, the breeding of the G. radiata is successful. The G. yniphora breeding, at the time the report on G. yniphora was made, had not been successful. I do not have proof that the G. radiata offspring from this breeding program are being sold to traders, but if it is not true, where in the world are all the hatchling G. radiata coming from!? If someone outside of Madagascar is producing all these offspring, they have an endangered species breeding program that would make the San Diego Zoo envious. Yes, there is a certain amount of mortality from road kill, but most are ending up as food, not only for the Japanese, but also for the native Malagasy population.
Many Asian populations, especially the poor, eat turtle and tortoise meat without any regard to its endangered status. It is just another meal and they either eat what they find or go hungry. I am constantly trying to tell people in Thailand that Clouded Monitors are highly endangered and killing them is not only a violation of Thai law, it is also a violation of CITES (international law), but all they can tell me is how good it tastes.
There is slight pyramiding in many G. radiata that I have seen here, but I have also seen many with no pyramiding. G. radiata might be prone to more pyramiding than other tortoises because of their fast growth rate. My young G. radiata are showing no sign of pyramiding- I am keeping my fingers crossed. The worst case that I have seen was caused by feeding it whatever was at that person’s home at the time, in another words, it was fed a diet in which no thought was made to what the tortoise should eat. It is a wonder that it survived, but G. radiata is very difficult to kill. Someone like that should never have such a wonderful creature, but it all comes down to who has the money, not who can take the best care of it. I am not sure why many tortoises do not pyramid as bad here as they do in Europe or the US. Maybe it is the high temperatures and high humidity? I think that diet has to enter the equation somewhere also. THESE ARE ONLY MY GUESSES AS TO WHY. If you can give the true answer about pyramiding, you will be the hero of many tortoise keepers!
