A report published by J.R. Harlan and E.B. Speaker (1969) in Iowa Fish and Fishing states that the fish weighed over 198 lb (90 kg). [18] The world record paddlefish caught on rod and reel weighed 144 lb (65 kg) and was 54.25 in (1.378 m) long. The fish was caught by Clinton Boldridge in a 5 acre pond in Atchison County, Kansas on 5 May 2004.
The paddlefish hunts plankton using thousands of tiny passive electroreceptors located on its extended snout, or rostrum. The paddlefish is able to detect electric fields that oscillate at 0.5–20 Hz, and large groups of plankton generate this type of signal.
The fish emits brief pulses from its electric organ; its electroreceptors detect signals modified by the electrical properties of the objects around it. [ 1 ] For the elephantfish , the electric organ in the tail (blue) generates an electric field (cyan).

The age of American paddlefish is best determined by dentary studies, a process which usually occurs on fish harvested during snagging season, a popular sport fishing activity in certain parts of the U.S. The dentary is removed from the lower jawbone, cleaned of any remaining soft tissue, and cross-sectioned to expose the annual rings.
Ampullae of Lorenzini (sg.: ampulla) are electroreceptors, sense organs able to detect electric fields. They form a network of mucus -filled pores in the skin of cartilaginous fish ( sharks , rays , and chimaeras ) and of basal bony fishes such as reedfish , [ 1 ] sturgeon , [ 2 ] and lungfish . [ 1 ]
