Table 3: Trial 1 electronic particle counts at 1, 6, 12, 24-h.Mean (n=3±SD) counts for bighead (BHC; top rows) and silver carp (SVC; middle rows) are compared across rows relative to particle size, sample time. Combined means (n=4±SE) for each particle size and sample time between species are also compared (bottom). Significant differences are indicated with different letter superscripts across rows.
