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).
