4 criteria including: 1) mangrove conservation; 2) efficient use of land, water and energy resources;
3) circular farming that combines algae, shrimp and fish farming to reduce production costs and
environmental pollution; and 4) use renewable energy to replace energy from fossil fuel sources to
achieve zero carbon emissions.

3.4.2. Model development
On an area of more than 6 hectares of land, the TOMGOXY (oxygen-rich shrimp) shrimp farming site
has a closed construction facility to ensure the cycle of the high-tech shrimp farming process.

The input water treatment area includes water treatment ponds with chemicals, sedimentation,
sand filtration and is ready with a volume of 10,000 m of water equipped with a microwave
3
system to kill cyanobacteria without chemicals. The commercial shrimp farming area consists
of 5 semi-submerged round ponds, each with an area of 1,000 m and 10 floating ponds on the
2
ground, each with an area of 500 m . These shrimp ponds have an inverted conical bottom, lined
2
with HDPE tarpaulin with a siphon in the middle that effectively collects insoluble organic waste.
Shrimp can be reared at a density of 300–500 shrimps/m per period. The ponds are supplied with
2
oxygen with a purity of over 90%, with a system that separates oxygen from the air with a capacity
of 1,000 kg/day.
Each shrimp pond has 2 multifunctional systems used to:

• Create one-way laminar water flow;
• Dissolve oxygen in water;
• Feed shrimp with automatic dosing unit;
• Online monitoring of DO, pH, salinity, water temperature, water level and sunshine with
smart sensor.
