Lake Tarpon History
The EPA has published a national fish tissue study that doesn't specifically cover Lake Tarpon, but the state of Florida has specific Lake Tarpon recommendations. The Florida guide recommends the following limits on fish consumption for a number of Florida's lakes, including Lake Tarpon:
Bluegill, Redear sunfish: Two per week
Black crappie: Two per week (One per week for women of childbearing age and young children)
Largemouth bass, Bowfin, Gar: Two per week (One per month for women of childbearing age and young children)
For specific recommendations on other lakes, check the guide from the Florida Department of Health.
