| Abstract: | "The problem of describing allometric growth during metamorphosis involving periods of shrinkage in over-all size is examined on the basis of measurements of three species of Vinciguerria published by Ahlstrom and Counts. The opinion of these authors that it is not at the present time practical to seek the ideal solution of a single equation before the entire cause of ontogenetic changes is confirmed. But it is shown that the superior resolving power of the ratio-on-size method of analysis will give a much clearer picture of the morphological changes taking place also during period of negative growth than does the size-on-size presentation. Examples are given to show how the ratio-on-size method clearly reveals inconsistencies between data and descriptions that easily develop in a concealed or inconspicuous manner by the use of the size-on-size approach. Rectilinear size-on-size regressions are in most cases incompatible with the import of the data on allometric growth in fishes"--P. 1... |
