Název v původním jazyce

Age and growth of non-native monkey goby Neogobius fluviatilis (Teleostei, Gobiidae) in the River Ipel, Slovakia

Popis výsledku v původním jazyce

Amongst the non-native Ponto-Caspian gobies that have invaded the Middle Danube is the monkey goby Neogobius fluviatilis (Pallas, 1814). Despite a strong specialization towards sandy substratum, revealed in a previous study, monkey goby is considered aninvasive species and therefore should demonstrate great plasticity in its biological traits. The main aim of the present study was to evaluate the age and growth of a non-native population of monkey goby from the River Ipel' in Slovakia. Six age groups (0 V) were observed in the sample from the River Ipel' (n = 165), with males demonstrating faster growth than females, which was reflected both in the smoothing cubic B-spline model and in the annual increment. The cubic B-spline model indicated a reverseLee's phenomenon, especially in males, which is likely to have arisen from the size selective mortality. Growth of invading monkey goby from the River Ipel' was slower than that reported for the species' native range.
