[Patterns of individual growth in the field slug Deroceras agreste (Gastropoda, Agriolimacidae)].
The growth of individual Deroceras agreste slugs from the date of sampling to the end of life has been studied under laboratory conditions. Seven out of 37 mollusks (approximately 19%) have shown a finite growth pattern, with their body weight reaching a maximum and decreasing thereafter. The data on these mollusks are well approximated by the finite growth equation. Other mollusks have not reached the maximum weight. In many cases, periods of a sharp decrease in body weight with subsequent return to the initial growth curve (compensatory growth) have been observed. In three animals, the growth curve has changed after such a decrease. A comparison of growth parameters in different individuals with the aid of the Ford-Wallford equation has shown that differences between them lack statistical significance. In generally, the slug D. agreste appears to belong to animals with the finite growth pattern.
