Краткое описание

The variability of the linear dimensions of the giant tropical prawn, Macrobrachium rosenbergii (De Man), depending on the density of its populations during the juvenile period was studied. The variability of its linear dimensions was assessed in terms of the degree of dispersion. In some populations, the dispersion of the body length of the specimens of the same age remained unchanged, whereas the density of their populations varied over a wide range. Constant variability was registered only in cultivating the animals in groups, which is indicative of the availability of a special mechanism supporting their variability at the population level.
