Study of migratory sturgeon captures in Romanian side of Danube River (Migration of Fishes in Romanian Danube River, № 3)

摘要

Study of fish captures could bring out valuable information on tendencies in stocks dynamics as well as on the level of "fishing pressure" on natural fish population. Decreasing amount of annual captures of marine migratory sturgeons that migrate in Danube River for spawning indicates a decline of natural stocks of these species. Present paper tries to show the main aspects of sturgeons fished in Romanian sector of Danube River, to discuss some relevant aspects that could help people to understand the real issues on this topic better and eventually find the best way to stop the decreasing tendency of wild population of three very interesting species of sturgeons: beluga (Huso huso Linnaeus, 1758), Russian sturgeon (Acipenser gueldenstaedti Brand, 1833) and stellate sturgeon (Acipenser stellatus, Brandt, 1833).
