Abstract

Survival and nacre formation was evaluated in freshwater mussel Lamellidens corrianus by varying sediment depth, calcium hardness of water and feeding ration. Different sediment depths (0, 3 and 6 cm), calcium hardness levels of water [(220.47 (T1), 282.63 (T2), 314.17 (T3) and 338.18 mg l-1 (T4)] and feeding rations [(1.5 x 106 (T1), 3.0 x 106 (T2) and (T3) 4.5 x 106 algal cells ml-1] were evaluated. Survival did not show significant difference while nacre formation was found to vary significantly (p<0.05) between different treatments. In the present study, sediment depth of 6 cm, calcium hardness of 338.18 mg l-1 and feeding ration of 3.0 x 106 algal cells ml-1 resulted in significantly (p<0.05) better nacre deposition.
