Description
  • Since 1997, three new Neogobius species (Neogobius kessleri, N. fluviatilis and N. melanostomus) have been regularly recorded in the Slovak part of the Danube River, formerly inhabited only by one native gobiid species (Proterorhinus marmoratus). The study of their food habits proved that the amphipod Corophium curvispinum, chironomid larvae and pupae, caddis fly larvae (Hydropsyche sp.) and mayfly nymphs (Ephoron virgo, Potamanthus luteus) were the most important food items contributing to the similarity of the diets of the gobiid species. Fish (0+ Zingel zingel and Sander lucioperca) appeared in the diet of N. kessleri only.

  • Od roku 1997 jsou ve slovenském úseku Dunaje pravidelně registrovány tři nové druhy rodu Neogobius (Neogobius kessleri, N. fluviatilis a N. melanostomus). V minulosti zde žil pouze jediný původní druh čeledi Gobiidae, a to hlavačka skvrnitá (Proterorhinus marmoratus). Studie potravního chování všech čtyř druhů prokázala, že hlavními potravními složkami jsou korýš Corophium curvispinum, larvy a kukly pakomárů (Chironomidae) a larvy chrostíků (Hydropsyche sp.) a jepic (Ephoron virgo, Potamanthus luteus). Ty byly také nejdůležitějšími komponenty potravní shody mezi těmito druhy. Ryby (0+ drsek Zingel zingel a candát Sander lucioperca) se vyskytovaly pouze v potravě N. kessleri. (cs)
