The biological pressure represented by non-indigenous macroinvertebrate species (NIMS)should be addressed in the implementation of EU Water Framework Directive as this can havea direct impact on the ’naturalness’ of the invaded macroinvertebrate assemblage. Thebiocontamination concept allows assessment of this deviation from naturalness, byevaluation of abundance and disparity contamination of an assemblage. This study aimed toassess the biocontamination of macroinvertebrate assemblages in Lithuanian rivers, therebyrevealing the most high-impact non-indigenous species, and to explore the relationshipbetween biocontamination and conventional metrics of ecological quality. Most of thestudied rivers appeared to be impacted by NIMS. The amphipods Pontogammarusrobustoides, Chelicorophium curvispinum and snailLitoglyphus naticoides were revealed as high-impact NIMS for Lithuanianlotic systems. Metrics of ecological quality which largely depend upon the richness ofindicator taxa, such as the biological monitoring working party (BMWP) score andEphemeroptera/Plecoptera/Trichoptera (EPT) taxa number, were negatively correlated withbiocontamination, implying they could provide unreliable ecological quality estimates whenNIMS are present. Routine macroinvertebrate water quality monitoring data are sufficientfor generation of the biocontamination assessment and thus can provide supplementaryinformation, with minimal extra expense or effort. We therefore recommend thatbiocontamination assessment is included alongside established methods for gaugingbiological and chemical water quality
