Thanks Bob for your brief explanation into sex

floating around...

If I understand the above correctly, there are
environmental factors that have an impact onto
sex determination in fish. Is it known if these
factors have an impact on the sex of the fish
AFTER it is hatched, or do they only influence
up to a certain time in the egg development?

Thanks, 
Wolfgang
