Abstract

The wider the spatial and temporal scales of a fish survey are the higher the chance that the methodology will vary, most probably in the configuration of the sampling equipment or the composition of the crew. It is important to know how these changes affect data quality. The objective of this study was to assess the effect of the differences both in the electrofisher equipment type (low power, battery powered vs. high power, generator supplied units) and in the operators when assessing fish assemblages in a non-wadeable lowland river in Hungary. We found that compared to the superior effect of "natural" spatio-temporal heterogeneity, pure methodological factors accounted for a low or moderate (
