Both Gulland and Holt’s (1959) and Fabens’ (1965)
methods produced reasonable values for maximum size and
longevity for both sexes but predicted unreasonably large
growth rates at birth (Table 4, Fig. 2). The predicted
maximum DW (DW∞) for males and females was 67–69 and
97 cm, respectively (Table 4). The predicted maximum
masses (M∞) were 11 and 45–50 kg for males and females,
respectively (not included in Table 4). Both methods
predicted similar longevity of 7.2–8.3 and 8.5–8.7 years for
males and females, respectively, when DW was used. When
mass was used, longevity was 7 and 9–11 years for males and
females, respectively (not included in Table 4). However, the
two methods suggested different and unreasonably high
