Osmotic behaviour of the freshwater mussel, Parreysia corrugata

  • R. Nagabhushanam

  1. 2.

    Parreysia corrugata appears to withstand low salinities up to 0.3% NaCl for longer period of time.

  2. 2.

    The lethal salinity appears to lie between 0.3% and 0.5% NaCl.

  3. 3.

    A study of blood chloride determinations in mussels in different salinities revealed that the animals showed regulation in very low salinities while at higher salinities they showed poikilosmotic behaviour.

  4. 4.

    In hypotonic media the mussels could regulate their water content but in hypertonic media the animals lost considerable weight due to loss of water.
