Sampling Methods

Quantitative samples of benthic invertebrates were obtained using a modified Hess sampler (0.071 m2, 500-μm mesh size) or a Surber sampler (0.063 m2, 500-μm mesh size) depending on the depth of water. At each site, eight to ten subsamples were taken. Samples were fixed in a 4 % formaldehyde solution in plastic bottles.

Study Extent	The sampling was carried out in the Váh River and the Čierny Váh River. Altogether, the research was carried out at 23 sites. Sampling was performed twice, during September 2015 and May 2016.

Method step description:

The benthic invertebrates were separated from the other organic and inorganic material and preserved in 70 % ethylalcohol. Non-insect benthic invertebrates were identified to the species level when possible using the identification keys of Goedmakers (1981), Horsák et al. (2013), Nesemann & Neubert (1999) and Timm (2009).
