Biotechnology for environmental depollution in aquaculture. Preamble-orgin of the pollution problem in aquaculture.
 

• The organic load in terms of unutilized feed, excessive feed (due to over feeding), fecal matter, molted exo-skeleton, dead algae etc. rich in protein and carbohydrates, settles at the pond bottom. 
•  
• This undecomposed or partially decomposed proteinaceous material creates anaerobic conditions and produces toxic gases like ammonia, nitrite, hydrogen sulfide etc. This contributes to the pollution of the pond bottom which deteriorates the healthy environment and causes severe damage to the prawn culture.
•  
• In such prevailed conditions there is a need for such a product which can be present at the bottom and augment the process of biodegradation so that the pollution load will be minimized.
•  
• ENVIRON-AC^TM is a unique bio-product through Biostadt Biotechnology Organization Techniques et Biochimie Appliquees (TBA). It provides a most optimum solution to the aqua problems.

•  
• A new bio-technological product to the aquaculture. 
•  
• Consists of consortia of large number of selective, non-pathogenic, beneficial, native microorganisms bio-fixed on a highly porous and natural material called cocolith.
•  
• Direct application to the pond, no need to brew out side the pond.
•  
• A bio-product successfully demonstrated in Indian aquaculture.
•  
• Obtained results indicate that ENVIRON-AC^TM is a successful, natural and aqua-friendly bio-product, which is able to solve the pond management problems.

•  
• Due to its presence ENVIRON-AC^TM with its specific, non-pathogenic, beneficial microorganisms continuously biodegrade variety of the accumulated organic load at the pond bottom. 
•  
• Removes the organic load through a continuous mineralization process in a systematic way and release nutrients into the pond environment.
•  
• Constant availability of the nutrients helps in stabilizing the algal bloom till the end of culture period.
•  
• Provides good survival rate as well as substantial growth over all other conventional processes.
•  
• Inhibits sludge formation at the pond bottom.

• ENVIRON-AC^TMis such a bio-product which immediately reaches the pond bottom after its application and lies there in an active state till the end of the shrimp culture cycle and takes care of the excessive organic load and its causative detrimental gases. 
•  
• The microorganisms used in this product are able to tolerate and are active at even high salinity conditions.

ENVIRON-AC^TM consists of basically two major components 

•  
• A consortia of a large number of non-pathogenic, beneficial and native microorganisms in a bio-fixed form. The details of micro organisms and their activity is shown in the flow chart. 
•  
• Cocolith is a natural calcareous matrix rich in Oligonutrients which supports the active growth of biofixed microorganisms.
•  
• Oligonutrients present in the Cocolith are CaO, SiO₂, P₂O₅, Fe, Cu, Mn, V, Co, B etc.

Observed advantages of ENVIRON-AC^TM over other probiotics
 

•  
• It is very important to develop an appropriate level of algal bloom. We recommend a pond water transparency (sacchi-disco of 35-45 cms prior to first application ofENVIRON-AC^TM).
•  
• Based on our experience a total quantity of 50-150 kgs/Acre of ENVIRON-AC^TM in split dosages of one application per month would be required depending upon the stocking density. See chart for application schedule.
•  
• Important : Dosage and time of adjusted based on condition prevailing in the pon from time to time.

Keep in cool and dry place.
