We are trying to expand our fish area by putting channel catfish in our deep water culture troughs where we grow vegetables. Since these catfish are only 3-4″, it seems to be working out ok so far since they aren’t trashing the roots of the plants and don’t seem to be eating the mosquito fish….yet. We did notice that when we pick up a raft, we have to be sure we don’t get catfish stuck and pulled out of water! This brings up the question, if we can keep catfish in the trough, do we really need a fish tank?!?
The short and admittedly not edge-of-your-seat video is short and was taken when our bell siphon is draining water into the trough, hence, strong flow left to right.
