MODELOS MULTIPLES PARA DETERMINAR EL CRECIMIENTO DE ORGANISMOS JUVENILES DE JAIBA AZUL CALLINECTES ARCUATUS EN CAUTIVERIO
A multi-model approach was used for select the best growth model for juvenile blue crab Callinectes arcuatus under culture conditions. Five variations of Schnute model and the oscillatory model (movb) of Somers were used as candidate models. Despite the oscillatory nature of growth data, the movb wa...

| Resumo: | A multi-model approach was used for select the best growth model for juvenile blue crab Callinectes arcuatus under culture conditions. Five variations of Schnute model and the oscillatory model (movb) of Somers were used as candidate models. Despite the oscillatory nature of growth data, the movb was not an adequate support for the data. The best models were case 1 for females, and case 3 for males. Akaike penalizes more severely the movb than other candidate models because it required estimating five parameters instead of four or two parameters for cases 1 and 3. The consequences of selecting a priori the von Bertalanffy model to describe the growth of juvenile C. arcuatus may be an unrealistic estimation of maxim carapace width (ac). However, neither the best fitted models are useful for estimating this parameter because only juveniles were included in the analyses. The best models fitted to data are not useful for estimation of this parameter, because only growth of immature crabs were considered. The best model adjusted to growth data of immature blue crabs are only valid for estimates of growth between sizes from 25 to 80 mm ac. |
