Daily ration of Antarctic silverfish (Pleuragramma antarcticum Boulenger, 1902) in the Eastern Weddell Sea
[EN] The daily ration of Pleuragramma antarcticum in the Eastern Weddell Sea was investigated from midwater and bottom trawl samples collected in the Antarctic in the summer of 1998. Using a gastric evacuation model that takes into account Weddell Sea temperature below zero and information on the pr...
