Summary: | The growth curve is a tool that can be used to determine the performance potential of fish at different ages. The aim of this study was to evaluate the growth curve of pacu (P. mesopotamicus) and the patinga hybrid (P. mesopotamicus × P. brachypomus) cultivated in a semi-intensive system. In the initial phase of the experiment, the pacu and patinga fish weighed 32.6 ± 7.5 g and 24.9 ± 7.1 g, respectively. The Gompertz model was adopted to describe the growth curve. At the end of the experiment, body weight, standard length, head length, body height and body width did not differ significantly between the pacu (625.9 g; 25.6 cm; 7.2 cm; 12.1 cm; 4.5 cm) and the patinga hybrid (727.1 g; 27.3 cm; 7.6 cm; 13.2 cm; 4.9 cm). The asymptotic value (parameter A), relative growth rate (parameter B), and age at the inflection point (parameter C) of the growth curve of the two species were similar for weight and for the evaluated morphometric traits. The asymptotic values obtained for weight in the pacu and the patinga hybrid were 1212.0 g and 1348.0 g, respectively. The growth curve of the patinga hybrid is similar to that of pacu, contrasting with the belief of many fish farmers. |

O objetivo do estudo foi avaliar a curva de crescimento do pacu (P. mesopotamicus) e do híbrido patinga (P. mesopotamicus x P. brachypomus) produzidos em sistema semi-intensivo. Foram utilizados no início do experimento pacu e patinga com peso de 32,6 ± 7,5 g e 24,9 ± 7,1 g, respectivamente. Foi utilizado o modelo Gompertz para descrever a curva de crescimento. No final do experimento, o peso corporal, comprimento padrão, comprimento da cabeça, altura do corpo e largura do corpo não diferiram significativamente entre o pacu (625,9 g; 25,6 cm; 7,2 cm; 12,1 cm; 4,5 cm) e o híbrido patinga (727,1 g; 27,3 cm; 7,6 cm; 13,2 cm; 4,9 cm). O valor assintótico (parâmetro A), taxa de crescimento relativo (parâmetro B) e idade no ponto de inflexão (parâmetro C) da curva de crescimento do pacu e patinga foram semelhantes para peso e características morfométricas avaliadas. O valor assintótico obtido para peso no pacu e no híbrido patinga foi de 1212,0 g e 1348,0 g, respectivamente. O híbrido patinga apresenta curva de crescimento semelhante ao pacu, contrastando com a crença de muitos piscicultores.UEL2020-08-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa científicaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3824110.5433/1679-0359.2020v41n5supl1p2285Semina: Ciências Agrárias; Vol. 41 No. 5supl1 (2020); 2285-2296Semina: Ciências Agrárias; v. 41 n. 5supl1 (2020); 2285-22961679-03591676-546Xreponame:Semina.
