Abstract: | An experiment was conducted for 12 weeks to determine the effect of feeding and starvation on truss and classical parameters in the external body of olive flounder, Paralichthys olivaceus. There was an increase in the truss dimension of body depth in the trunk region of the fed group at the end of the experiment (P < 0.05). In the olive flounder, the trunk region dimensions, including body depth measurements, are likely to be compromised by variability related to differences in the feeding of fish from different habitats. Classical dimensions in relation to the anterior–posterior body axis decreased and classical dimensions of head characteristics increased upon starvation but decreased upon feeding (P < 0.05). These results suggest that these morphometric parameters may be a useful index of nutritional status in olive flounder. |
