Abstract

The serum, calcium, sodium, potassium and protein value were measured during different phases of reproductive cycle in Heteropneustes fossilis (Bloch) due to effect of varied calcium concentrations. The calcium value was higher then and Potassium value Protein during spawning period pointing a more demand of calcium which is necessary for the functioning of a enzyme thereby also helps in hardening of eggs while protein meets an extra energy demand during this period. An increase in serum, sodium level was also observed during spawning period than pre and post-spawning.
