Over 11 years of study, fish species richness decreased continually and significantly in the tailwater of the Warta River (Poland). The smallest sample size required for estimating species richness of fish communities in the tailwater increased. As the rarefaction method has rarely been applied in fishery research, its strengths and drawbacks in cases similar to this are discussed.
