Historically, the Atlantic sturgeon Acipenser sturio L., 1758 was considered the only sturgeon species that inhabited rivers of the Iberian Peninsula. Nevertheless, in a recent paper, Garrido-Ramos et al. (1997) identified specimen EBD 8174 (museum collection of the Doсana Biological Station, Spain), from the Guadalquivir River, as the Adriatic sturgeon Acipenser naccarii Bonaparte, 1836, suggesting that both A. sturio and A. naccarii could be native to Spain.

The lake sturgeon spawns from early May to late June, but enters spawning streams as soon as the ice is gone. They spawn in swift water, rapids, or the bases of small falls in water 2-15 feet deep. Where suitable spawning streams are unavailable, lake sturgeon may spawn in wave action over ledges or around rocky islands.

Atlantic Sturgeon - Acipenser oxyrhynchus - English
URL: http://www.dnr.cornell.edu/Sarep/fish/Acipenseridae/atlsturg.html

Atlantic sturgeon males mature at a length of 4 feet and 12 years old; females, at 6 feet and 18 years old. Females may release as many as 2 million eggs during spawning over a rubble bottom in running water more than 10 feet deep. Spawning runs begin in the spring, but actual spawning may not occur until July. No nest is built, but the adhesive eggs stick to rocks or logs on the bottom. No parental care is given the eggs or young. The young sturgeon hatch a few days after spawning. They may spend up to 4 years in fresh water before moving out to sea.
