The American paddlefish (Polyodon spathula) lives in the slow-flowing waters of the Mississippi River and Ohio River systems (and was historically found in the Great Lakes).
Due to the value of their eggs, paddlefish are a constant target for poachers, and they are subsequently a protected resource over a large part of their range.

 Chinese Paddlefish - Wikipedia, the free encyclopedia
The Chinese Paddlefish (Simplified Chinese: 白鲟; Traditional Chinese: 白鱘; Pinyin: báixún), also known as Chinese Swordfish, is among the largest freshwater fish, and one of two extant paddlefish species.
Due to overfishing, the Chinese Paddlefish is endangered now, and officially recognized by the People's Republic in 1983 to prevent fishing of paddlefish young or adults.
Paddlefish are also threatened by dams (like the Three Gorges Dam), which divide the population into isolated groups.

Paddlefish became commercially important around the turn of the century, due in part to the decline of lake sturgeon populations, and became an important recreational species after fish began concentrating below dams (Carlson and Bonislawsky 1981).
Paddlefish growth rates are greater in reservoirs than riverine systems due to increased food availability, and populations flourish in reservoirs with available natural spawning habitat (Marzolf 1990, Pflieger 1975, Houser and Bross 1959).

Paddlefish fingerlings are now reared both intensively (raceways and circular tanks) and extensively (ponds) and techniques have been developed to train paddlefish to accept commercial diets.

 Paddlefish
Because the young paddlefish are too elusive to find and count, biologists at Fort Peck have been unable to solve the mystery of their population status.
Biologists found that when young paddlefish rushed to escape an approaching boat, their anatomy propelled them to the surface where they could be counted or captured with long-handled dip nets.
Although their understanding of the paddlefish in Fort Peck is far from complete, biologists now know that reproductive success varies greatly among the years, and that the difference could be a result of the species’ specific requirements for spawning.
