The present study was carried out for 109 days from 6th November, 2016 to 23rd February, 2017 to assess how tomato and fish production respond to calcium supplement in aquaponics. Tilapia (Oreochromis niloticus) was released at the rate of 10 fish/16 L water tank and two tomato saplings were planted in each replication. As the source of calcium, chicken egg shell powder was added in T1 (1kg/decimal) and T2 (1.5kg/decimal) and T3 was control. The daily growth rate and survival rate were 1.68±0.009, 1.59±0.016, 1.6±0.03% and 66, 70, 60% in treatment T1, T2 and T3, respectively. The higher production of tomato (73.58 tons/ha/109 days) and fish (295.03 tons/ha/109 days) T1 signifies the potential of egg shell powder as source of calcium in addressing disease problem in tomato.
