Seasonal diet pattern of non-native tubenose goby (Proterorhinus semilunaris) in a lowland reservoir (Musov, Czech Republic)

Popis výsledku v původním jazyce

The tubenose goby (Proterorhinus semilunaris) is a gobiid species currently extending its area of distribution in Central Europe. The objective of the study was to evaluate the annual pattern of its feeding habits in the newly colonised habitats of the Mušov reservoir on the Dyje River (the Danube basin, Czech Republic) with respect to natural food resources. In the reservoir, tubenose goby has established a numerous population, densely colonising stony rip-rap banks. Its diet was exclusively of animalorigin with significant dominance of and preference for two food items -- chironomid (Chironomidae) larvae and waterlouse (Asellus aquaticus), which contributed 40.2 and 27.6%, respectively, to the total food bulk ingested. The index of preponderance forthe two items was also very high, amounting to 73.8 and 26.5, respectively. In the annual pattern, a remarkable preference for chironomid larvae was recorded in the summer period whilst waterlouse were consumed predominantly in winter mo
