Resumo: |
The marine shrimp Litopenaeus vannamei can be cultured in waters of different salinities,therefore they tolerate an ample band of salinities (0,5-60). Of this form, the objective of this present work was to compare the production data, of this crustacean, when cultured in freshwater or salty water, using mathematical models. The models, to relate the variables of management and of production, had been formulated on the basis of a data base with 278 cultures. To estimate the models parameters, it was used technique of the squared minimums.The variable selection was carried through the process of "Stepwise" associated to the Box and Cox’s transformation. The adequacy of the equations and the normality estimated, for the errors, had been analyzed on the basis of the variance analysis, in the Durbin-Watson statistics, on the residue analysis and normality test. In all the formulated equations the management variables, culture in salty water (CAS) was selected, evidencing significant difference (p<0,05) between these culture systems. |
