One thing I will be doing before Christmas this year is to set up a saltwater aquaponics system at home (I already have a 6,000L freshwater system). Only small as a proof of concept, but then to see with what I can do with it from there.
Fish types are easy as both trout and barramundi can live in full seawater and I can also get black bream fingerlings if needed.
Plants then need some consideration. Obviously I’ll be putting seaweed into the system, and this will be an Ulva variety of some description. However, seaweed on it’s own is unlikely to be attractive to a wide audience.
Hence I’ll need some sort of growbed to be able to grow non-seaweed type plants. Samphire (see the photo) is the first thing that comes to mind. The growbed will also provide me with some or all of my biofiltration. If I can find a number of plants that will be of interest, then increased growbed volume can be my entire biofiltration, if not I’ll hook up a moving bed filter with some Kaldnes media in it.
Better start researching samphires in Western Australia !
