Correlations between fillet yield and morphometric measurements in relation to the different weight classes of black pacu (Colossoma macropomum).
| Weight classes | Fillet yield | |||||
|---|---|---|---|---|---|---|
| CT | CP | CC | CirC | CirM | CirCau | |
| 1 (<1.2 kg) | −0.641∗∗ | −0.606∗∗ | −0.758∗∗ | ns | −0.683∗∗ | −0.517∗∗ |
| 2 (1.21 to 1.8 kg) | −0.504∗ | ns | ns | −0.643∗∗ | −0.612∗∗ | −0.508∗∗ |
| 3 (1.81 to 2.4 kg) | −0.637∗∗ | −0.617∗∗ | −0.422∗ | ns | −0.411∗ | ns |
| 4 (2.41 to 3.5 kg) | ns | ns | ns | ns | ns | ns |
| 5 (>3.51 kg) | −0.418∗ | −0.489∗ | ns | −0.451∗ | −0.449∗ | ns |
∗ Significant (p < 0.05); ∗∗significant (p < 0.01); ns = not significant; CT: total length; CP: standard length; CT: head length; CirC: cranial circumference; CirM: medium circumference; CirCau: caudal circumference.
