On the instantaneous natural mortality rate of Champsocephalus gunnari, South Georgia (Subarea 48.3)

The discussion of the results suggested that M=O.56 should be ... this value could be used in the future on an equal footing with M=0.35 (CCAMLR-VIII, paragraph 49 ... from positive to negative (Table 9, Figure 1). It may therefore be assumed that the rate of natural ... Richter-Efanov (M=0.22). The author himself admitted that the results varied to such a degree that ...
