Thank you, some one else knows some basic facts
of hormone breeding! Hopefully we get some eggs fertilized and see what happens. With all the hootin and hollerin about it being impossible and that there is no evidence that it has been done, where is the evidence of failed attempts? We wont know what happens unless we try, and yes T1 it is really easy get eggs of pretty much any large fish fertilized!

I believe some people are hard at work finding this out as we type....maybe also hoping a bit to get a tankload of small st's
[/QUOTE]If there is, no one in the U.S. is doing it for sure. No reason too. And like I said above the lack of evidence of even failed attempts is pretty strange, but like Ive said a couple times now a fellow told me it has been done and I have no reason to doubt him because of what he does.

Another thing, with all the sceptic about indo's being st like, even if you breed st's it would be very hard to convince some people here they are real st's

Damn, I never thought of that!!
T1, since you have kept dats in a glass box for years now what kind of insight can you give me?
Lets change it up a bit...cichla kelebri...that fish would be EASY to do, all large cichlids are so why isnt any one doing that?
Quick run down how this works cause I think some people believe that hormone breeding is wrong. Here is how it works in a nutshell.
Certain environmental factors such as the onset of the rainy season trigger mature fish's pituitary gland to release a certain "XYZ" hormone. This hormone triggers the maturation of the eggs and sperm and that takes no time at all around a day or two with most fish. So the way hormone breeding works is, you take the exact "XYZ" hormone the fish's pituitary gland produces (carp pituitary glad is often used, even human growth hormone but we have the exact "XYZ" hormone and its the same in all fish) and you inject it in the proper amounts into the fish.
By injecting the fish, you are essentially "over riding" the environmental triggers that induce fish to spawn. In other words YOU are the environmental factors needed. Often times all one needs to do is inject the fish and they will just spawn and raise the eggs on their own and of course this would be best case scenario for us! Other times the eggs and sperm need to be harvested...pretty easy. The hard part comes after and that is keeping the eggs and very young fry alive. Before some one chimes in and says, "you didnt do this or do that...," I know I left out many things on purpose...just in case!
A story to relate how environmental factors trigger fish to spawn. A LFS of mine had about dozen HUGE true green snook cichlids in a 300 gallon display for years...no breeding. One night the tank crack and all but a couple inches of water leaked out. The fish were thrown into another tank and boom, eggs instantly and they had so many young green snooks that I kid you not it took them probably 18 months to sell/kill them all! You see, the cracked tank triggered the release of the "XYZ " hormone (again this hormone is UNIVERSAL) which caused the fish to spawn in less then 24hrs.
I will be picking up an 8" ST and a 10" ST Monday. These fish will not be injected until we are certain we know if they are mature or not. My NTT will be the guinea pig and Im 95% certain we will see results from that fish as at 12" that is approaching max size and most perches mature well before they reach max size. And who knows we may fiddle fart around with what comes out of the NTT with what comes out with the STs.
You see T1, I'm no keyboard commando like you. I have done my research, I associate my self with and talk to people that do this kind of stuff for a living. I have high hopes that this will work but I also fully understand that a million things could go wrong. Unfortunately, the only thing holding us back right now is money.
