Abstract
    In the Netherlands glass eels, Anguilla anguilla, are caught for research purposes at various sites. Catches at four sites are compared, using an analysis of variance. It is concluded that three sites basically give the same information, while one, the most southern site, shows independent annual fluctuations. As a side effect of this study, a different indicator for catch sizes is proposed: geometric means reflect more accurately the underlying frequency distribution than common means do.
