Fig. 1. The growth rate of pupfish from the high food (100% rations), medium food (50% rations), and low food (20% rations) treatments differed (P<0.0001). Tukey pairwise comparisons showed no difference (ND) in body length among the three treatments on the 1st measurement day (15 days post-fertilization) when fish were initially assigned to treatments. Body size deviated significantly by day 36 and remained different among treatments through the conclusion of the experiment on day 141. Values are means ± s.e.m. (N=7-8).
