Exotic sturgeons in the Vistula Lagoon in 2011, their occurrence, diet and parasites, with notes on the fishery background

Exotic sturgeons in the Vistula Lagoon in 2011, their occurrence, diet and parasites, with notes... The Siberian sturgeon Acipenser baerii and the sterlet Acipenser ruthenus were recorded for the first time in the Vistula Lagoon in 2011. Among 66 sturgeons collected between April and December 2011, the Siberian sturgeon was the most numerous species (77%); however, a significant seasonal variability was observed, with sterlet dominating in the catches in late autumn of the same year. The stomach contents of the two species differed widely: Siberian sturgeon (14.9–42.2 cm standard length, SL) fed on crustaceans (Cercopagis pengoi, Oithona sp., Neomysis integer) (10.7% IRI), larvae and pupas of insects (Chaoborus sp., Chironomus sp., Polypedilum sp., Procladius sp., Culex sp.) (88.9% IRI) and fishes (Neogobius melanostomus, Osmerus eperlanus) (0.5% IRI), whereas sterlet (24.0–34.4 cm SL) consumed crustaceans (N. integer) (64.3% IRI), larvae of insects (Chironomus sp., Polypedilum sp.) (20.3% IRI) and fish (N. melanostomus) (15.4% IRI). Single Siberian sturgeon (4.3%) were found to harbour the parasitic nematode (Raphidascaris acus). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Applied Ichthyology Wiley

Abstract

The Siberian sturgeon Acipenser baerii and the sterlet Acipenser ruthenus were recorded for the first time in the Vistula Lagoon in 2011. Among 66 sturgeons collected between April and December 2011, the Siberian sturgeon was the most numerous species (77%); however, a significant seasonal variability was observed, with sterlet dominating in the catches in late autumn of the same year. The stomach contents of the two species differed widely: Siberian sturgeon (14.9–42.2 cm standard length, SL) fed on crustaceans (Cercopagis pengoi, Oithona sp., Neomysis integer) (10.7% IRI), larvae and pupas of insects (Chaoborus sp., Chironomus sp., Polypedilum sp., Procladius sp., Culex sp.) (88.9% IRI) and fishes (Neogobius melanostomus, Osmerus eperlanus) (0.5% IRI), whereas sterlet (24.0–34.4 cm SL) consumed crustaceans (N. integer) (64.3% IRI), larvae of insects (Chironomus sp., Polypedilum sp.) (20.3% IRI) and fish (N. melanostomus) (15.4% IRI). Single Siberian sturgeon (4.3%) were found to harbour the parasitic nematode (Raphidascaris acus).
