Fig. 6. Summary of mussel condition (gonad index, GI, and condition index, CI), water temperature and thread production for all low flow experiments. Water temperature is shown as both tank temperature and mean (± s.e.m.) bottom temperature at Bass Rock (year 2003–2004). Values for GI, CI and threads produced are means (± s.e.m.) of pooled experimental mussels (N=30–60).
