The American Paddlefish (Polyodon spathula) is an anadromous fish found in both freshwater and brackish water bodies of North America. They are filter-feeders with late maturity, longer lifespan, and their roe is a commonly popular caviar. Male paddlefish are larger than females and all swim upstream to spawn. Besides, spawning is communal and they don’t build their nest.
The Paddlefish is also called spoonbill, shovelnose, and is the only living member of the family Polyodontidae. The paddlefish is a primitive fish since it has fewer morphological changes. They are identified by a broad paddle-like rostrum, small but poorly developed eyes, and smooth-skinned scaleless spindle-shaped body.
American Paddlefish have a total length between 5’-7’ (1.52-2.13 m), body height of 8.5”-11.5” (21.6-29.2 cm), and an overall weight in the range of 60-200 lb (27-91 kg). The typical lifespan of the American Paddlefish is 20-30 years.
