 The black drum is usually found in or near brackish waters.Larger, older fish are more commonly found in the saltier areas of an estuary (closer to the ocean) near oyster beds or other plentiful food sources.Juvenile fish have 4 to 5 bold vertical black bars on a light background and can be mistaken for Sheepshead at first glance, but are distinguished on closer inspection because sheepshead have teeth and black drum have chin barbels.
