Fig. 3. Effect of food ration on pelvic fin development. (A) A significantly smaller proportion of fish in the low food ration treatment developed pelvic fins when compared to the medium and high food treatments (P=0.0048). Values are means ± s.e.m. (N=7-8), and letters indicate pairwise differences (Tukey HSD test). (B) In all treatments, there was a trend toward a low proportion of fish with pelvic fins when reared at higher temperatures (P=0.0392). Each data point represents the mean of two replicated buckets per temperature value (except the point indicated by asterisk, which represents a single bucket).
