Jerry Ferguson, a marine biologistfor the Louisiana Department of Wildlife and Fisheries, says: "Redfish generally begin to move offshore when they reach 4 years of age or 8 to 10 pounds. Prior to that, they feed on just about everything inshore, from crabs, menhaden and shrimp to mullet." Regardless of the fact that seatrout and redfish are from the same family of drum, once trout reach a certain size, their eating habits begin to differ from redfish. "Once trout reach 4 pounds, their diets move more toward an all-fish diet of mullet and menhaden - they especially like mullet," says Ferguson. "Schools of redfish will disrupt schools of mullet, creating a feeding advantage for trophy-trout anglers." Both Ed Hix and Steve Jones agree that once a school has been located, anglers need to determine which species they've hooked and try to fight it accordingly. Hix explains: "Trophy trout and redfish strikes are similar, but trout tend to surface more readily, with shorter bursts, while redfish tend to make steady, protracted runs. Once you determine species, get redfish in quickly for release while backing off drags to carefully coax trophy-size specks into the release well."
