The most up to date information on goliath grouper was published Open source (free download). Google Endangered Species Research (ESR) journal, go to vol 7, number 3.
To all those interested on killing and eating goliath grouper (a.k.a. jewfish) known also as Epinephelus itajara, I would remind them that goliaths have shown extremely high levels of methyl mercury. (see ESR publication above). Scientists think this is due to the goliaths spending almost the first decade of their lives in mangrove habitats, picking up all the pollution coming from our cities and towns. Methyl mercury is extremely poisonous when ingested, it causes mental retardation in children, anomalies in the unborn fetus when ingested by pregnant or planning to be pregnant mothers, erectile dysfunction in men, and it is thought a direct precursor of mental diseases such as Alzheimer's and Parkinsons. I don't understand why someone will be willing to subject himself/herself, or his/her loved ones to such danger by eating goliath grouper meat.

I found the reference you made to jewfish/methyl mercury content. From the abstract, I see that the research was done only in Belize and that none of the small jewfsih had mercury content which exceeded US standards. Maybe this means that fisherman could be allowed to take small jewfsih and leave the large ones to breed?
Is there any research from Florida which indicates that mercury content is an issue of conern? If not, why not?
Also, where do you come up with the information that jewfsih spend nearly 10 years in the mangroves? My understanding of recent research is that 3-4 years they are moving out of that habitat and are much. much larger at age 10 than fish normally found in shallow mangrove habitats.
