Abstract:

Measurements were made of the variations in shell length and weight of the bivalve Dreissena polymorpha during the period from April until July of the next year. The bivalves being divided into four size classes were placed in cages submerged at several sampling stations of the lake. At the same time, materials were collected for the assessment of both, the shell and body weight increments. Determinations were made during the season, of the increase in shell length and weight within the distinguished size classes. The most intensive growth was recorded for the young individuals, while the slowest for the oldest animals. An increase of dry body weight was noted young individuals: several-fold decrease was found for the older bivalves. This observation has been related to a summer reproductive period and the deterioration of feeding conditions.
