saltose, panvit aqua, spa gelly, aqua boost used as growth promoter and bio-pond, biogrow, aqua pure, gasstrap, metrix, geo-rich bio-aqua 50 and aqua magic as toxic gas
reducer. Approximately 11 trade names of antibiotics were marketed in the selected area
among them some were used by the fish farmers. Their main active ingredients were
