Abstract
This study highlights the relationship between growth of scales and their different parameters of Platycephalus indicus L. Six body regions were selected for the study. The dorsal side of fish body contains ctenoid scales while, ventral side of fish body contains cycloid scales. The results show that there is no relationship present between the growth of scale length and its width in ctenoid scales and scale does not grows in its width with proportion to the growth of its length. In cycloid scales, the growth of scale width is strongly related to the growth of scale length and shows that scale also grows in its width with the growth of its length. Further, the weak correlation between scale length and selected scale parameters in ctenoid scale shows that growth in scale length does not affects the growth of other scale parameters. In cycloid scales, it was observed that growth of all selected scale parameters is related to the growth of scale length. It is notable that the results for scale width and number of radii in both ctenoid and cycloid scales were found significant
and shows that number of radii also increase when scale grows in its width.
