The Impact of Ozonated Water Treatment On Growth Rate Srikandi tilapia (Oreochromis aures x niloticus)

This is the latest version of this item.

Abstract

The impact of ozonated water treatment on 'Srikandi' tilapia was assessed using ozone reactor with an airflow velocity of 1.5 L/min at a voltage of 10 kV, which leads to that the dissolved oxygen (DO) content increases from 0.99 to 11.11 mg/L/ The ozonized water treatment was divided into five groups based on the length of treatment period: 5 minutes as group I, 10 minutes as group II, 15 minutes group III, 20 minutes as group IV and 0 minutes (reference scale). The fish growth rate was measured in terms of length and weight per seven days for 30 days. The result indicated that the fastest growth rate of Srikandi tilapia occured at the group III. The fastest specific growth (SGR) of the fish occurs at the group III and the fastest Relative Growth Rate (RGR) of the fish occurs at the group III. The oxygen content, temperature, salinity to match the growth of Tilapia Srikandi are vital elements in Tilapia farming management. These results are considered to be useful to increase the production rate of Srikandi tilapia farming.
