I need more time, sorry. |
Hi Douglas,
That's really interesting about the yellowy colour due to pollution. I never thought it might be because the molluscs are sick. Do you think it is the mercury,PCBs or pesticides? These three things seem to be THE major water pollution players.
Can you imagine, on top of everyday survival(tough enough), battling nucleation mortality and being subjected to antibiotics and growth hormones, the poor oyster can't even get a steam of fresh water to filter. It hurts to think about it.
Don't worry, you don't need to get the lead out for me! Anything you can come up with is greatly appreciated. No rush.
