Fig. 3. Mean myoelectric frequencies for red and white muscle fibres. Each point denotes the mean ± S.E.M. (N=5–6) from one fish. White muscle fibres (blue circles) showed a significantly greater mean frequency than red muscle fibres (red triangles). There was no significant linear regression between mean frequency and mean fibre diameter for either fibre type. Solid lines indicate the average mean frequency across all fish for each muscle fibre type.
