I love barramundi... and not being able to eat it duringpregnancy was pure torture... but i ate it anyway. I figured, it was a one off and it wasnt as if i was drinking/smoking/taking drugs etc. I think fish would have to be eaten in large, regular amounts for it to really be drastically harmful? Maybe for vegetarians perhaps that only eat fish?
BTW- The barramundi i had was beautiful, and i dont regret eating it !!
