Do instream habitat variables and the abundance of brown trout Salmo trutta (L.) affect the distribution and growth of stone loach, Barbatula barbatula (L.)?
Along a stream, we investigated whether the abundance of stone loach (Barbatula barbatula, L.) was related to the presence of brown trout (Salmo trutta, L.) and instream habitat variables. First, a field survey was carried out where different habitat variables and the densities of both species were quantified and subjected to principal components analysis. Then the abundance of stone loach was rel
