Abstract

Calcium is essential to mollusk’s life, because is associated with shell formation
and metabolic processes that are essential to maintain their homeostasis. The aim
of this work was to verify the mobilization of calcium in the haemolymph and
shell of Biomphalaria glabrata (strain BH) exposed to different calcium carbonate
concentrations. Sixty days old snails were used for this study, distributed in five
groups: four groups exposed to different concentrations (20, 40, 60, 80 mg/L)
of calcium carbonate and one control group. The exposition time was forty-five
days. Fortnightly, the snails were sacrificed by cardiac puncture for haemolymph
extraction. The concentration of calcium was determined in the haemolymph,
using diagnosis kits (Doles Reagentes®) and for the calcium content in the shell,
a modified volumetric method of complexing was employed. The results showed
an increase of the calcium content in haemolymph and a decrease in shell of snails
exposed to 15 days of 20mg/L of calcium carbonate. In the other exposed groups, the calcium concentration in the haemolymph was inversely proportional to the amount of calcium in the shell. We conclude that in snails exposed to different amounts of calcium, mobilization in the hemolymph and in the shell occurs according to the amount of calcium available.
