Název v původním jazyce

A comparison of point abundance and continuous sampling by electrofishing for age-0 fish in a channelized lowland river

Popis výsledku v původním jazyce

For monitoring purposes, it is important to find a method that accurately estimates age-0 fish assemblages and that is relatively quick and inexpensive. We compared time effectiveness and accuracy of estimating age-0 fish assemblages obtained by point abundance and continuous electrofishing on the lowland Morava River (Danube River basin, Czech Republic). Forty sites were surveyed by each strategy along two types of shoreline: submerged vegetation and boulder bank. Both strategies yielded similar qualitative data (species richness, relative proportion of species, and size structure) along each shoreline type. Point abundance sampling required a shorter amount of survey time than did continuous sampling. We conclude that point abundance sampling is themore suitable method for routine sampling of age-0 fish assemblages in lowland rivers.
