Popis:	He et al. (2015) described piscivory patterns in themain basin of Lake Huron for 1984–2010, during which there was also a pattern of stepwise declines in the abundance of dominant prey fish species. The approach of He et al. (2015) was to couple age-structured stock assessment and fish bioenergetics models to estimate prey fish consumption and to compare these patterns with prey fish biomass from a bottom trawl survey. Riley andDunlop (2016) were highly critical of themethods and conclusions reached byHe et al. (2015). They claimed that we incorrectly interpreted the bottom trawl survey data and did not account for uncertainty. We respond to these and other criticisms below, which we find do not undermine our findings.
