The saying “you are what you eat” holds true for methylmercury in fish, as fish obtain most of their methylmercury from their diet. Fish mercury concentrations are also affected by processes within the fish that occur after mercury is ingested, such as growth, metabolism, and clearance rates . Mr. Harris has developed and published bioenergetics models that couple methylmercury fluxes to energy budgets for fish (Harris and Bodaly 1998).
