Our continual studies in aquaculture are showing a pattern where the same beneficial bacterial species which are capable of living in aerobic or anaerobic environments, delivering two completely different outcomes in these areas for your crop health. The other area of interest is the importance of not clearing the water in aquaculture ponds.


Bacillus Species in an aerobic environment, produce enzymes that are highly beneficial to gut health in crustaceans and fish species, with results continually showing increased crop survival and size. This is also being shown to heavily reduce bacterial disease species within the aquatic environment, consequently dramatically improving the health of the aquatic crop.


Bacillus species in an anaerobic environment are producing enzymes which see a dramatic reduction in feed uptake showing a reduction in gut health. This can be seen dramatically on harvest where there is low crop yield with dramatic size differences within the end crop production, with a large amount of runts. There is also no evidence of bacterial disease reduction.


This has become evident with the use of TWC sinking blocks in aquatic crops where the ponds or dams are less than 3 foot deep, where it is a continual aerobic environment delivering continual outstanding results. Ponds or dams over 3 foot deep become quite anaerobic with the same TWC sinking blocks not delivering any desirable outcomes. We are understanding that these ponds need to maintain turbidity as most farmed species do not like clear water. From these results we developed a new formula for aquaculture AP+CB, Probiotic Culture Block for Aquaculture.  AP+CB elements are designed to deliver the same probiotic bacteria without delivering the clarity to the water. These have been designed to sink for shallow water aquaculture ponds and a floating bent block which enhances aerobic enzyme production in deeper ponds.  The curve in this bent block radiates the sun’s heat through the top surface, resulting in beneficial bacterial groups increasing their enzyme production.


AP+CB floating bent block has been placed in aquaculture ponds with an average depth of 8 to 10 feet, which resulted in maintaining an aerobic environment with increased probiotic enzyme production. We have now been able to deliver the same outstanding results as we have delivered with shallow water aquatic crops.
