Growth models and parameter values.

Parameter estimates and log-likelihood values estimated using the Francis (1988a) method for tiger shark sex-specific and both sexes combined data sets. Bold text indicates optimally parameterized model for each data set. Numbers in parentheses are bootstrap 95% confidence intervals for the best fit models. PCL ∞ was converted to TL∞ using coefficients in Table 3. Different models represent step-wise inclusions of further parameters. Abbreviations as follows: g108 = mean annual growth increment at 108 cm, g240 = mean annual growth increment at 240 cm, v = coefficient of variation of growth variability, s = standard deviation of measurement error, m = mean measurement error, p = outlier contamination, u = seasonality amplitude, w = time of year when growth is at maximum, k = von Bertalanffy growth constant, PCL∞ = asymptotic maximum precaudal length, TLL∞ = asymptotic maximum total length. The different models represent step-wise inclusions of parameters.
