Description 80-82
Changes in the rate of oxygen consumption, ammonia excretion and the tissue
content of total ninhydrin positive substances in the black clam, Villorita
cyprinoides, were studied during the exposure of the animal to salinities
0, 5, 10, 15 and 20 ppt. The content of total ninhydrin positive substances was
found to increase with an increase in ambient salinity, maximum concentration
was found at 15 ppt. Rate of oxygen consumption also showed an increase with
increase in salinity. Rate of excretion of ammonia nitrogen decreased with an
increase in ambient salinity. The role of ninhydrin positive substances in the
osmoregulation is depicted and the existence of a degradation-synthesis balance
for the regulation of osmotic effector pool is suggested.
