Notes: Specific growth rate (SGR) for body mass (bm) or carapace length (cl) was regressed against condition index (CI) and all biochemical indices for a particular tissue (liver, heart, or blood) (n = 27 for each variable). When specific growth rate was regressed against condition index and biochemical indices for all tissues together, the resulting models were identical to models 1–2 (for SGRbm) and model 6 (for SGRcl). Variables are listed in the order in which they were selected by the models. Significant p-values are indicated in bold. Abbreviations are the same as in Table 1.
