Fig. 6. The distribution of muscle fibre diameter in the fast myotomal muscle of Atlantic salmon: (A) the final sample of the ambient treatment group sampled 988 days post-fertilisation; (B) the final sample of the heated treatment group sampled 997 days post-fertilisation. Smooth distributions were fitted to 800 measurements of fibre diameter per fish using a nonparametric kernel function. The broken lines represent the probability density for individual fish, and the solid line represents the mean probability density function for each group.
