Fish poo fertilises veg farm
26th April 2018

Ornamental fish are helping to provide nutrients for a vegetable grower in Australia’s New South Wales. Vegetable farmer Luke Tutt said: “The basis of our farm is the fish becoming the fertilising agents for our produce.”
 
Each fish tank holds about 4,000 litres of water and contains the native eel-tailed catfish and Japanese koi. The water then feeds into beds filled with gravel in which vegetables such as eggplant, baby tomatoes and basil and grown, reports the ABC News.
 
Once the water has made its way through the different vegetable beds, it is cycled back into a sump tank where it is filtered before being returned to the fish tanks.
