BIO-D  is a novel, effective probiotic specially made for Aquaculture security. Development of probiotics is essential for denitrification in the recirculation of Aquaculture systems. Nitrite is an important component in the nitrogen cycle, but it has become a matter of great concern for the intensive Aquaculture industry in recent years. The Nitrite in the water rapidly increased because the substantial amounts of uneaten feedstuff and aquatic animal excretion. Nitrite accumulation in the ponds could cause  Shimp/fish diseases outbreak and result in huge Economic losses.

Physical, chemical and biological methods used in Aquaculture for removing Nitrite, but physical and chemical methods cannot remove Nitrite without secondary pollution and residues. Hence, the best way to remove Nitrite is via the biological methods. Bio-D is highly effective in removing Nitrite from ponds and prevent the culture animals not to become weak.
