Question by Olly: Is aquaponics legal in the UK?
If you didn’t know Aquaponics is a system that has a fish tank and a plant growing bed linked together. Water is circulated around the two to provide the plants with nutrients from fish waste. This system is very efficient and i would love to make one however i am unsure on its legality.

I am trying to find out if aquaponics is legal in the UK? My step dad and i would like to make one but my step dad told me that he is unsure about it because there is something about if a farmer wants to own fish they have to own a license. Does anyone know if there is a document online about this? i would like to know what is the maximum i can have but i am also interested in possibly taking this further as a Commercial Business so i would also like to know about owning a mass of fish and if i really do need a license.

Any input will be helpful 😀
