Ichtiofauna lewobrzeżnych dopływów polsko-ukraińskiego odcinka Bugu
Journal Title: Roczniki Naukowe Polskiego Związku Wędkarskiego - Year 2009, Vol 22, Issue
Abstract
The fish fauna of tributaries of the Polish-Ukrainian section of the Bug River was investigated in August 2008. At 38 sampling sites a total of 5995 individuals representing 26 species were collected by electrofishing. The dominant reproductive guilds were phytolithophils and phytophils. Only two lithophilic species (spirlin and chub) were recorded. Aquatic environment in all studied rivers was strongly human-impacted, mostly by pollution and channel regulation. In comparison to previous data the species richness decreased in the Wożuczynka, Wełnianka and Udal Rivers, while it increased in the Bukowa, Huczwa and Uherka Rivers. Two invaders were recorded: Chinese sleeper Perccottus glenii in the Wełnianka River and monkey goby Neogobius fluviatilis in the Uherka River.
