Prawn toilets need targeted current flow management……..to concentrate…

To disperse concentrated shrimp pond solids and directionalize in pond currents towards a solid removals system a highly energy efficient robotically managed system on floats can inject air/oxygen, deliver benthic feed gently and move solid particles with its automatic sensor reading, pond mapping, history and 100% coverage software.

Dispersal, aeration, oxygenation plus feeding passes mode available with 2016 prototype.

In background on wall counter current for live fish trials
perfect
hehehe – test running system – 17 years delay
