You may not be able to tell from this photo, but the white sturgeon is North America's largest fish. To date, the largest on record was caught in 1898 and weighed approximately 1,500 pounds! Vintage photographs reveal fish so large that, once caught, horses were needed to pull them from the water. In the late 1800s, commercial fisheries began to target this species to meet the demand for caviar (sturgeon eggs) and smoked sturgeon. These fisheries grew so rapidly that they collapsed towards the end of the 1800s due to over-fishing. The population began to rebound in the early 1900s when California banned commercial and sport fishing of white sturgeon. In recent years management of fisheries has also improved – environmentally safe farms now raise white sturgeon for fillets and caviar, helping to ensure populations in the wild remain.
