ALLOMETRIC GROWTH AND LIFE EXPECTANCY OF THE BIVALVE DIDACNA BARBOTDEMARNYI (GRIMM, 1877)
KHLOPKOVA Marina Vladimirovna
Allometric characteristics, at the second stage of mollusk growth, more accurately reflect the environmental condi-tions. In assessing the growth of mollusks, it is found that the largest annual increase in the length of the shell is ob-served up to 2,5 years. Revealed has been that Didacna barbotdemarnyi (Grimm, 1877) in moderate environmental conditions after two years of growth comes to maturity, and after 6 years the growth rate slows down. The formation of shells on the principle of negative allometry b < 1 is characteristic for the inhabitants of hard sand-shell and silt-shell soils.
