The phylogenetic relationship of five sturgeon species in the South Caspian Sea was investigated using mtDNA molecule. Sequence analysis of mtDNA D-loop region of five sturgeon species [Great sturgeon (Huso huso), Russian sturgeon (Acipenser gueldenstaedtii), Persian sturgeon (Acipenser persicus), Ship sturgeon (Acipenser nudiventris), Stellate sturgeon (Acipenser stellatus)] and DNA sequencing...

Acipenser oxyrinchus is considered extirpated in Europe, but numerous breeding populations still exist on the Atlantic coast of North America. An adult female A. oxyrinchus, 2500 mm total length and 120 kg wet weight, was accidentally fished on 24 November 2010 near the coast of Gijón, Asturias, Spain. The fish was identified by its morphological pattern as well as by mitochondrial and nuclear ...

The present work reports behavioural responses by young-of-the-year (21-30 cm) Atlantic sturgeon Acipenser oxyrinchus oxyrinchus and shortnose sturgeon Acipenser brevirostrum to nine binary combinations of dissolved oxygen saturation (40, 70 and 100%), temperature (12, 20 and 28°C) and salinity (1, 8 and 15). Both species showed no acclimation effects and similar discrimination and avoidance re...
