i have done a lot of research on the plachon. the only info available on farming these fish that i could find comes from thailand, and it is, as usual, subsistence-based non-scientific and antiquated.
given the physical properties and their hardiness, (high tolerance to poor water quality, plus they have sub-branchial organ like catfish so can breathe air),i would think that they could be farmed at extreme densities in a recirculating system, and the very poor fcr the thais are getting (you woulld get the same from any other fish if you used the thai approach),is can probably be attributed to what and how they are feeding and rearing them. anyway, even if you got a 1:3 fcr, you would probably score, since the selling price is so high.
