Table 1.

For pellets, feces, and regurgitated fish, the total number of analyzed samples is displayed followed by the number of samples containing any hard parts and the fish individuals which were morphologically identifiable to order level or lower. Finally, the number of samples testing positive for fish DNA is noted per sample type. Note that for regurgitated fish samples, identifications were also made based on soft remains such as tissue
