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

  • Original language description

    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.

    Porovnání bodového a kontinuálního elektrolovu pro odlov 0+ ryb

  • Czech description

    Pro účely monitoringu 0+ ryb je důležité nalézt metodu, která nejenže dává přesný obraz plůdkového společenstva, ale také je relativně rychlá a levná. Ve studii jsme porovnávali účinnost a vhodnost dvou elektrolovných strategií: bodového a kontinuálníhoelektrolovu pro monitoring 0+ ryb na řece Moravě. Cekem bylo proloveno oběma strategiemi čtyřicet lokalit podél dvou typů břehové linie: ponořené vegetace a kamenného záhozu. Obě strategie poskytly podobná kvalitativní data o společenstvu 0+ ryb (druhovápestrost, složení společenstva, velikostní struktura). Bodový odlov byl časově méně náročný než kontinuální. Bodový elektrolov se jeví jako vhodnější metoda odlovu pro rutinní monitoring 0+ ryb v řekách.
