To grow vegetables in water from a fish pond full of nutrients might sound like a brilliant idea, but is it really profitable? A study by reaearchers from the Wageningen Univesity showed that more than half of the 1000 commercial aquaponic farms worldwide make a loss. This was mainly the result of low market value for the produced vegetables and fish that were farmed. Before starting an aquaponics farm it is important to look at the market prospects. A niche in the market needs to be found that could make aquaponics more profitable. Tilapia and catfish usually won’t make it because they sell for far to cheap. Perch, burbot and pike could be interesting alternatives for the European market as their market value is much higher.
