Abstract
Arabidopsis thaliana (ecotype Columbia) was planted on sponges in 4 tanks with continuous aeration through airstones. Different amounts of fish under the same growing conditions for 5 weeks. An equal food-fish ratio was given to all tanks except the control which was a hydroponic setup with Murashige and Skoog solution, a plant growth medium, at 1/5 strength. The growth solution was changed once per week and fish water was partially changed every two weeks. pH, temperature, ammonia, nitrite, nitrate and plant number were recorded once per week. A slow growth was observed in all tanks and the control treatment died on the 3rd week.
