OHF Solution


OHF has built experimental aquaponic systems where we grow both fishes and vegetables.


Food security for communities residing in areas where traditional farming is challenging due to factors like poor soil quality, lack of space, and limited water supply.

Potential Solution

Aquaponics addresses the issue of food security by providing a reliable source of fresh produce and protein to rural farmers.

How it Works?

Aquaponics is a sustainable farming technique that combines aquaculture (fish farming) with hydroponics (growing plants in water). The technique uses a symbiotic relationship between fish and plants, where fish waste provides nutrients for the plants, and the plants filter the water for the fish. This creates a closed-loop system that requires less water and energy compared to traditional farming methods. Aquaponics can be used to grow a variety of crops, such as leafy greens, herbs, and fruits, while also providing a source of protein through the fish. The technique is becoming increasingly popular in urban and suburban areas where space is limited, and traditional farming is challenging.

Our Experience

OHF has tested this small-scale aquaponics solution by


  1. Proper water quality: The water in an aquaponic system must have the right balance of pH, dissolved oxygen, and nutrients to support healthy plant and fish growth.
  2. Adequate space and lighting: Plants need sufficient space and light to grow, so the system must provide adequate space for plant roots and sufficient light for photosynthesis.
  3. Proper fish selection: The fish selected for the system should be suitable for the environment and have a high tolerance for variations in water quality.
  4. Efficient filtration: The system must have effective filters to remove solid waste and maintain water quality.
  5. Proper temperature control: The water temperature should be kept within a suitable range for both the plants and fish to thrive.
  6. Maintenance and monitoring: Regular maintenance and monitoring of the system are essential to prevent issues such as disease outbreaks and water quality problems.

What is next?

To develop a self run commercially viable aquaponics system for rual farmers where the harvest of crops and fishes are higher than the maintenance cost.
