Figure 26. Stage composition and species composition of Calanus spp on selected stations along two transects Utsira-StartPoint (Stn 1-25) and Hanstholm-Aberdeen (Stn 5-13). Positions shown in map, Figure 21. Mean copepodite stage index (CSI) of Calanus spp (C. finmarchicus and C. helgolandicus) CSI is calculated as abundance-weighted average stage number, and the ratio between 1 (all CI) and 6 (all adults).
