Abstract: 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 perio… Show more

“…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.…”

“…Combining ability includes GCA (general combining ability) and SCA(Specific combining ability) (Hayman, 1957;Costa et al, 2019). GCA represents the average performance of parental lines in hybrid combinations, which is mainly improved by pure propagation; it provides information concerning the magnitude of additive genetic effects, which can be used to identify superior parents in breeding programs.…”

“…Combining ability analysis is important in studies of aquatic animal hybrid breeding, which is an important genetic improvement approach; combining ability analysis is also a prerequisite for the utilization of heterosis (Hedgecock and Davis, 2007). There have been many reports regarding combining abilities in aquatic animals (Deng et al, 2010;Bosworth and Waldbieser, 2014;Costa et al, 2019;Chaivichoo et al, 2020). Chaivichoo et al (2020) reported that the total combining ability was higher in male catfish than in female catfish 0.25 to 362.64 vs. 0.23 to 190.32, suggesting that the growth performance of a hybrid is largely dependent on additive genetic variation from its male parent, followed by variation from its female parent.…”

“…Among the animal producing sectors in Brazil, aquaculture has drawn attention due to the substantial increase (61.4%) in production rate between 2009 and 2012 (FAO, ). Brazil presents a diversity of native species with high production potential, fast growth, food conversion, rusticity and good acceptance in the consumer market (Baldisserotto & Gomes, ; Costa et al, ; Gonçalves, Nascimento, Costa, Leal, & Viveiros, ). Among the native species is the lambari, currently considered a species of great potential for aquaculture (Abimorad & Castellani, ), with production of 270,912 tons in the year of 2014 (IBGE, ), representing a viable alternative for income generation for fish producers (Silva, Lopes, Fernandes, & Henriques, ).…”
