Sonny, you have a pretty good eye. That well-marked little fish is a banded drum, Larimus fasciatus, closely related to the silver perch. These two species, along with several others found in our estuaries, are small members of Sciaenidae, the drums and croakers. But since they rarely take a hook, we see them only as you did, captured in a bait trawl. We are all familiar with their heftier cousins, spotted sea (speckled) trout, red drum and black drum. The drum family is abundant around the world, and often the dominant family around tropical and subtropical estuaries. One peculiar feature of the drums is that the lateral line extends all the way to the tip of the tail fin. Your banded drum tops off at about 8 or 9 inches, and is found along the U.S. south Atlantic and Gulf coasts south to Vera Cruz, Mexico, though are rare in South Florida. While we consider banded drum as estuarine residents, they do venture offshore and may be found several hundred feet deep.
