For the quantitative characteristics of the morphology of two groups of spinal cord neurons in the cherry salmon at the early stages of ontogenesis, the fractal dimension and some more traditional morphometric indices, such as the total length of neuronal branches, the number of terminal branches and branchpoints, and the cell area, are determined. The values of the morphometric indices and the fractal dimension of the bivariate neuronal pattern are shown to increase in the course of ontogenesis from the first to the second year of fish life. The correlation between the main morphometric value and the fractal dimension is found, and their correspondence to the morphometric modifications of the dendrite tree in the neurons investigated during ontogenesis is detected.
