“…The determination coefficients ( R 2 ) adjusted to the obtained equations were relatively high for weight and weight of the body components, demonstrating the importance and efficiency of the morphometric measures and ratios in the determination of weight. For Luxinger et al (), the measurements and morphometric reasons can be used with precision to estimate weight of the body components of the species Pirarucu ( Arapaima gigas ). However, the coefficients of determination were low for body yields, corroborating with the results found by Diodatti et al ().…”

“…Moreover, a selection of 64 fish (8 per tank; 32 per experimental treatment), representative of their reference groups in terms of average body weight and variability, were measured for total length, standard length, head length and maximum height. The morphological indices (condition factor, cranial index, relative profile) were calculated according to Luxinger et al (2018). The fish were also dissected to measure the hepatosomatic index (Ighwela et al, 2014) as well as the carcass and fillet yields.…”

“…A mais alta correlação entre as variáveis foi encontrada ao relacionar o peso e o comprimento total (0,9948). Luxinger et al (2018) ao avaliarem a correlação entre peso e medidas morfométricas em pirarucus com peso corporal médio de 9,18 ± 0,1 kg e 104 ± 0,3 cm de comprimento, também observaram alta correlação (r = 0,93) entre as variáveis.…”

“…As medidas morfométricas apresentam forte correlação com peso vivo e com componentes corporais (carcaça, cabeça, camada de carne, couro e vísceras) em pirarucus com peso médio de 9,18 ± 0,1 kg (LUXINGER et al, 2018). Em outra espécie de grande interesse comercial como as tilápias, foi observado forte correlação entre peso e rendimento de carcaça vindo a contribuir com informações para a indústria de filetagem (MACEDO-VIEGAS; SOUZA; NASCIMENTO KRONKA, 2008).…”
