Multi-model inference for improved estimation of growth in the longnose spurdog Squalus blainville
In age and growth studies, many species seem to follow a different growth trajectory than the traditionally applied von Bertalanffy growth model (VBGM). To test a methodology for improving growth modeling in poorly studied chondrichthyans, 568 longnose spurdogs of Mediterranean origin were aged. A set of seven growth models were fitted to the obtained age-length data. Comparisons in growth model accuracy based on the Akaike Information Criterion allowed the assessment of the best model. In the case that no model fitted the data correctly, a multi-model inference (MMI) was carried out based on model averaging. The results provided evidence that the growth parameters inferred with the VBGM should be used with caution.
