Mark,

Heard of anyone growing them in aquaponics systems......or even small recirculating aquaculture systems?

No, I haven't but I expect a lot of research will be done on these and a few other estuarine species that live in predominantly fresh water.

Hi Gary


Flounder are grown in Brunei by McFarm - It sounds like fast food but it is actually a joint venture between the Mitsubishi Corporation & the Brunei government. The connection goes back to the early days of Independence when the Sultan of Brunei had a plan to make Brunei self sufficient in beef and goats. He ended up importing several hundred beef cattle but after a few years I think they found cattle production was not going to work here so he bought a station in the Northern territory and now all the Aussie grown halal beef is flown in.

As for the flounder, they are grown in huge tanks that supply part of the nutrient for basil/tomato production (floating raft) and the fish are exported to Japan.

There is no shortage of fish here in the markets, aquaculture is big here. Mainly prawns but also Barra, Grouper and lots of local species grown in cage farms on the rivers.

I have visited a few of the Hydro operations and we often buy hydro lettuce from a farm owned by a big chinese supermarket chain.

Hi Dave,


As for the flounder, they are grown in huge tanks that supply part of the nutrient for basil/tomato production (floating raft) and the fish are exported to Japan.
APHQ member Hygicell told me that Dover sole and turbot are grown in Europe in shallow tanks stacked in tiers. If I recall correctly, the tanks were only about 300mm deep.

Given that flounder are of similar conformation (flat fish), I wonder if they'd grow in similar circumstances.
