Tarpon (Megalops atlanticus) fish species information

Scientific Name
Megalops atlanticus

Common Name
Tarpon

Biology
Inhabit coastal waters, bays, estuaries, mangrove-lined lagoons, and rivers. Often found in river mouths and bays, entering fresh water. Large schools may frequent particular spots for years. Feed on fishes like sardines, anchovies, Mugilidae, Centropomus, Cichlidae and crabs. The swim bladder, attached to the esophagus, can be filled directly with air and permits the fish to live in oxygen-poor waters. Has high fecundity, a 203 cm female is estimated to produce over 12 million eggs. Spawn in waters which can be temporarily isolated from the open sea. Transparent leptocephalus larvae migrate into estuaries. Famous for its spectacular leaps when hooked. Marketed fresh or salted. Large scales are used in ornamen
