THE EFFECT OF VARIOUS CULTIVATING MEDIA OF AQUAPONIC ON DECREASING OF NITRATE AND PHOSPHATE IN COMMON CARP (Cyprinus carpio) CULTURE

Abstract

This reasearch aimed to know the effect of various aquaponic media on decreasing of nitrate and phosphate level in common carp culture. This research was designed with Completely Randomize Design with four treatment and three replications. Treatments consist of one control (without aquaponic), aquaponic with pumice media, aquaponic with fern roots media, and aquaponic with coconut fiber media. Pumice media gave significant value in  decreasing nitrate and phospate level. Nitrate and phospate level decreased of 65,55 % and 94,06 %, respectively. Aquaponic with pumice media result 69,3 % of survival rate and 2,3 % of spesific growth rate per day.
