family of the order Cypriniformes – Native to South Asia.

The researchers placed Zebra fish embryos in dishes
containing fluoxetine, which is sold under the
brand name ‘Prozac’, for six days…

Biologists at the University of Ottawa have discovered exposing
fish embryos to Prozac affected the aquatic creatures’ ability
to manage stress for generations, prompting a call for
further research into the lasting effects of this
anti-depressants on humans.

This may be a cause for concern given the high
prescription rates of fluoxetine to pregnant women.

…Indeed, salmon are unaffected by natural
1 ppm fluoride in ocean water where calcium
is extremely high but are narcotized by industrial
fluoride in soft water at only 0.3 ppm (Damkaer & Dey)


Millions of Salmon have instinctively know this for
thousands of years, that is why they go to so
much trouble to swim up rivers to lay
their eggs – in fluoride free water.
