“…The explanation for these responses rests with the similarities between the common effects of fry and fingerling environments and the spawning season (PONZONI et al, 2005;KHAW et al, 2009). Nguyen et al (2010) reported values for the effect of the common environment for morphometric measurements of tilapia from 4% to 5% of the total variation, unlike Ponzoni et al (2005) who found the range to be from 15% to 26%.…”

“…They concluded that it was unnecessary to use all these features in a program of genetic improvement, unlike the work of Nguyen et al (2010), who also worked with tilapia and found lower values of genetic correlations. These responses suggest that the characteristics change during the animal growth.…”

“…Most authors do not include the larval effect in their analysis models, and consider just the hapa effect (Rutten et al, 2005a;Charo-Karisa et al, 2006;CharoKarisa et al, 2007;Nguyen et al, 2007;Nguyen et al, 2010), which corresponds to the fingerling effect in the current study. This can be explained by the fact that these authors employed a system of artificial embryo incubation, whereby, soon after hatching, the larvae are transferred to fry hapa, resulting in a single random environmental effect.…”

“…However, knowledge of the changes that occur in other related traits, such as morphometric measurements, as a result of selection for weight gain is also important (Nguyen et al, 2010;Charo-Karisa et al, 2007). Fish that have more width and depth lead to the perception of higher yield meat eating and are preferred by consumers .…”

“…Considerando que os critérios de seleção podem ser diferentes dos usados para características de acasalamento (Ribeiro e Legat, 2008), Rutten et al (2004) e Nguyen et al (2010) estudaram o impacto no peso e no rendimento de filé utilizando o peso corporal e as características morfométricas como critérios de seleção em tilápia-do-nilo. No entanto, pouco são os trabalhos em que os animais são avaliados em diferentes idades no período de cultivo com o objetivo de estabelecer a seleção precoce e, ainda, apresentar ganhos indiretos para características de desempenho e morfométricas.…”
