The system uses

Biochar reactor to convert all residues and purpose grown crops (especially bamboo and acacia) to biochar for use as a growing media, filter and for feeding to fish with wood vinegar (1% biochar with ,25% wood vinegar).
Heat from biochar reactor maintains optimum temperature for fish and pl,ants
Biochar used as a medium for improve nutrient uptake in either pots tanks or troughs. Note with biochar water flows through troughs for only 1-3 hours per day reducing electricity requirements.
Aeration pond to grow water plants, fingerlings and filter water
