Paddlefish have been referred to as "primitive fish" because the Acipenseriformes are among the earliest diverging lineages of ray-finned fish, having diverged from all other living groups over 300 million years ago. Both living and fossil paddlefish are found almost exclusively in North America and China. [5]
American paddlefish are among the largest and longest-lived freshwater fishes in North America. [26] They have a shark-like body, average 1.5 m (4.9 ft) in length, weigh 27 kg (60 lb), and can live in excess of thirty years. [ 27 ]
The estimated time of the divergence between sturgeons and paddlefish varies. An estimate based on 30 protein-encoding nuclear markers suggest 204.1 million years ago, research on mitochondrial genomes suggest 155.2 million years ago, and Bayesian dating based on the combined matrix of molecular (mitogenomes) and morphological characters set ...
Alex Cord on location (1993) performing the voice-over and on-camera work for The Paddlefish: An American Treasure. Exotic and Unusual Fishes of North America is a series of PBS documentary television specials about three species of American fish: The Alligator Gar: Predator or Prey?, The Paddlefish: An American Treasure, and Sturgeon: Ancient Survivors of the Deep.
Sturgeon range from subtropical to subarctic waters in North America and Eurasia. In North America, they range along the Atlantic Coast from the Gulf of Mexico to Newfoundland, including the Great Lakes and the St. Lawrence, Missouri, and Mississippi Rivers, as well as along the West Coast in major rivers from California and Idaho to British ...
The paddlefish had likely been suffering for a very long time, a fishing guide said. Fishermen save fish from surprising, painful situation. ‘Probably happy to be caught’
The American paddlefish is one of the largest freshwater fish in North America. Closely related to the sturgeon, it is one of only two extant taxa in the paddlefish family (the other being the Chinese paddlefish). Fossil records of paddlefish date back over 300 million years, nearly 50 million years before dinosaurs appeared.
