File List Peacock2015_Ecosphere_Supplement.csv (MD5: 3e7c19c31b83ac4911b19a5056c3906b) Description Peacock2015_Ecosphere_Supplement.csv – Summary data from predation experiments involving juvenile pink and chum salmon prey and coho salmon smolts as predators. Column headings are: <b>Experiment</b> – Experiment numbers 1 through 27, where each experiment consisted of paired trials; one with clean prey and one with lousy prey. <b>Date</b> – Date of the trial. <b>Net pen</b> – Which of the two experimental net pens the trial took place in (see Fig. A3). <b>Treatment</b> – No lice or lice, depending on whether the trial used prey that had no sea lice or were infested with at least one sea louse of a chalimus II or more advanced stage. <b>Number of coho</b> – number of coho predators in the trial. <b>Length of trial (h)</b> – the duration that the predators had access to prey in hours. <b>Number of pink at start</b> – the number of pink salmon prey at the beginning of the trial. <b>Number of chum at start</b> – the number of chum salmon prey at the beginning of the trial. <b>Number of pink consumed</b> – the number of pink salmon prey consumed during the trial calculated as the number of pink at the start minus the number of pink at the end. <b>Number of chum consumed</b> - the number of chum salmon prey consumed during the trial. <b>Preference</b> – the value of α calculated by Eq. 8 in the main text.
