Cumulative consumption of food pellets during the 15 day NPF feeding experiment, separated into pre-trial (top), trial (middle) and post-trial (bottom) periods, for the control and NPF-treated shrimp. A and B refer to the two containment groups. NPF-treated individuals had their diet enhanced with a daily addition of 2 μl of 10^–3 mol l^–1 synthetic Litva-NPF I peptide. Each treatment and group combination contained 10 individuals (see Table 2 for statistical results). Error bars show the standard deviation.
