“…The linearity between the variables can be explained by the study data obtained in a single evaluation, which was the commercial weight considered for Serralmideos (Costa et al, ; Mourad et al, ). If animals were evaluated at different times or during growth, the behavior among these variables could be different.…”

The objective of this work was to evaluate the association between morphometric variables and carcass characteristics in Pirapitinga. We used a thousand specimens of Pirapitinga with an average weight of 1,200 g, which were stunned, slaughtered, weighed, measured, and processed for morphometric and processing yield analysis, to obtain weights, carcass and fillet yields. Initially, the linearity of the variables was verified. Pearson's simple and partial correlation tests were performed between all metrics. Track analysis was performed considering the weights and yields of carcass and filet as dependent variables and the others as independent variables. Ridge regression models were used to eliminate the effects of multicollinearity among the independent variables. Observations showed that the simple correlations between body weights and yields were superior to the partial ones in terms of magnitude. The length and circumference of the specimens were the measures most linearly associated with weight, carcass weight and fillet with rib weight. As for carcass yield and fillet yield, linear correlation coefficients were low and not significant when associated with body weights.With the path analysis, we could observe significant positive correlations between the morphometric measurements for weight, carcass weight and fillet with rib weight.The standard length, body circumference and body circumference/body height ratio are the most correlated. The latter are the most important variables in the evaluation of body weights in Pirapitinga fish. They can serve as criteria for indirect selection in searching for fish with better carcass characteristics. As for fillet and carcass yields, the morphometric variables have not shown to be efficient for indirect selection. K E Y W O R D Sbreeding fish, correlation, multivariate, path analysis, round fish

“…Colossoma macropomum, also known as tambaqui, is a freshwater fish native from the North of Brazil that has high-quality meat and excellent productivity; regarding growth, it can reach up to 90 cm in length and 30 Kg of corporal weight (De Mello et al, 2015;Marcos, 2014;Mourad et al, 2018). Because of that, tambaqui is not only one of the main food sources in such region but also of interest for aquaculture.…”

“…With the large production of tambaqui in Brazil, the study of growth curve of such fish becomes necessary to evaluate its developmental behavior in different environments and optimize production (Mourad et al, 2018), as it has been done for tilapia (Ansah & Frimpong, 2015;De Lima Amancio, Da Silva, Fernandes, Sakomura & Da Cruz, 2014), the most produced fish in the country (IBGE, 2016). Mathematical modeling is commonly used to describe populational dynamics and have been largely used in aquaculture, such as Malthus, Verhulst and Gompertz (Cruz, Rosa & Cruz, 2016).…”

Tambaqui (Colossoma macropomum) growth behavior was evaluated through the Gompertz mathematical model. Different curves were built for the body weight, head length, body height and body length, which were measured for eight months. Projections of the four morphological characteristics of C. macropomum from the fry/juvenile until fattening stage. The modeling aimed to estimate the growth pattern of the tambaqui population being cultivated in nettanks in the state of Tocantins, Brazil. Through the Gompertz model, the corporal growth pattern of tambaqui was estimated and the construction of projection curves indicated that the fish is still in growth phase after reaching the features being considered to slaughter. Also, the model predicted the maximum corporal length of tambaqui (87.61 cm) and that the fish would take approximately 20 years to achieve it. The goal of the present work was to study the bodily growth pattern of C. macropomum and contribute to the development of novel cultivation methods to optimize the production of such fish.

General and specific combining ability in Serrasalmidae

et al. 2018

This work was carried out to predict the combining abilities, both general and specific, for performance traits and bodily yields of Serrasalmidae. Ninety-six 30-day-old juveniles were purchased from two commercial fish farms, 12 of each of the following eight genetic groups: pacu, pirapitinga, tambaqui, tambacu, tambatinga, patinga, paqui and piraqui. Six fish from each genetic group were grown in 500-L fibreglass tanks (two tanks per genetic group) until they were 495 days old. At the end of the growth period fish were weighed, subjected to morphometric analysis and processed to obtain their bodily yields. Two nuclear markers and one mitochondrial marker were used to confirm the identity of the animals. Combining abilities were obtained using the method proposed by Griffing in 1956 (Australian Journal of Biological Science, 4, 463-493) adapted to a mixed models analysis, environmental effects were estimated by the empirical best linear unbiased estimator method and genetic effects (general and specific combining abilities) were estimated with the empirical best linear unbiased predictor. Predictions of the combining abilities of advanced hybrids were obtained by the mixed models mixture method with normal distributions. Tambaqui showed higher general and specific combining abilities than the other groups for most of the variables, making it the most important genetic group. General combining ability makes a greater contribution to phenotypic variance than specific combining ability for most variables, indicating a predominance of genes with an additive effect in the control of evaluated traits.
