PostSubject: influencing sex of fry by changes in water temperatures.....   Thu Feb 03, 2011 7:49 pm
i would say more fiction than fact-

I played with this theory and put it into practice on my first 6 batches.... it hardly made a difference at all...
and bearing in mind you could ask the same question if you varied the temperature could it increase or decrease
the mortality rates?

I will leave you to ponder that thought Smile
