Our DNR and DHEC have updated their fish consumption advisory now listing certain bodies of water [most of our coastal plain rivers!] as "Do not eat any" of the catfish because of mercury contamination. Other areas have "One serving a week" or "One serving a month" advisories. Obviously the mercury levels in those areasare low enough that it dissipates out of our bodies for continued consumption. My question for anyone much more learned on the subject thanI is if fish from those "do not eat areas" were caught, tagged,and released alive into other bodies of water not contaminated [private ponds], would the mercury levels in their bodieslikewise diminish over a period of time so that they would be safe for consumption?
