Resumo: | The marine shrimp Litopenaeus vannamei may be reared in a wide range of salinity (0.5-60.0 g L-1). In this study, the production data of shrimp reared either in oligohaline (0.5-5.0 g L-1) or salty waters (25.0-40.0 g L-1) were compared using mathematical models. The models considered variables related to management and production, and were formulated using a database with 278 culture cycles from different shrimp farms in Northeastern Brazil. The least-squares technique was applied to estimate the model’s parameters. The selection of variables used the Stepwise process associated to Box and Cox’s transformation. The adequacy of the equations and the normality estimated for the errors were analyzed on the basis of the analysis of variance in the Durbin-Watson statistics, on the residue analysis and the normality test. For all the formulated equations, the variable ‘culture in salty water’ was selected, evidencing significant differences between these culture systems. |

Desta forma, objetivou-se comparar dados de produção desse crustáceo quando cultivado em águas oligohalina (0,5-5,0 g L-1) ou salgada (25,0-40,0 g L-1), utilizando-se modelos matemáticos. Para relacionar as variáveis de manejo com as de produção, os modelos foram formulados com base em um banco de dados com 278 cultivos comerciais da região Nordeste do Brasil. Para estimar os parâmetros dos modelos, utilizou-se a técnica dos mínimos quadrados. A seleção das variáveis foi realizada com o processo de Stepwise associado à transformação de Box e Cox. A adequação das equações e os pressupostos de normalidade, para os erros, foram analisados com base na análise de variância, na estatística de Durbin-Watson, na análise de resíduo e no teste de normalidade. Em todas as equações formuladas, a variável cultivo em água salgada (CAS) foi selecionada, evidenciando diferença significativa (p < 0,05) entre esses sistemas de cultivo.Editora da Universidade Estadual de Maringá2009-03-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campoapplication/pdfapplication/mswordhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/263810.4025/actascianimsci.v30i4.2638Acta Scientiarum.
