Gender Changed By Hormones


Recommended Posts

I found the thread on another forum where Victoria Parnell wites that

Some Thai breeders introduce a hormone to the fry tanks to create more "males". Interestingly, although they look, act, and can spawn like males, the ones that nature intended to be female will still only sire female offspring. It is assumed that the reason for this is because the fish still carries an xx chromosome.


So they were not true parthenogenic fish. That's what happens when you can't remember everything to the finest detail :rofl:

But what does everyone think of this adding-hormones-to-fry-tanks business?
