nificance difference. That situation may happen,when two sample from the same living place, from the same population, the difference of averages of these samples may be significance too. In this case I thought to everithing exept that, the method of examenation is not good. Por the increasing the reliability of averages lot of times used to augment the number of specimens. Then happens that hundredth millimeter differences separate significantly during the variational statistic calculations . By the help of allometrical method can survey whole sizes of species, to avoid the mistakes and dont appreciate systematicly with mistakes, such values,which has no taxonomical values and depends of extents. At finish sum up the results ,it was ascertained that the quantitative qualities how much exert the individual's morphogenesis of population of Rhodens sericeu s aroaro s BLOCH. During íny examenation I definded the developmental speed of measurements, compared tothe length of body to weight of body, and defined the equation of lines of changes in oeasurements which typical to the examined population. In fallows it was found that the variational statistic is not suitable to characterize the fish population,to the species, because for itself gives only a static picture from the measurements of populations. Before we characterize the species with taxoncsaical numbers, supposingly necassary to survey the cojscenainig species about sizes by allometrical calculation®.
