<p>Freshwater rainbow trout eat bugs native to my area, including bsfl, also some small river fish, zoo-plankton, algae, worms, duckweed might be palatable. Also the commercial fish feed, corn and soybeans with some by-catch, is not complete, so I want to put natural foods into the pellets. This means anything that can be cultured will help feed the fish. Also most of the fish feed is lipids and protein, comparable to bsfl, so the worms I hope will counteract that, otherwise small fish when…</p>

<p>I've read (in the Freshwater Aquaculture book that Cosmo lent me) that midge larva can really improve tilapia growth far beyond the actual weight of the larva eaten. I suspect that they may provide one of the more limiting amino acids. And actually there is some research into growing midge larva as fish feed.</p>

A pellet machine might be quite the investment but If the worms and larvae were mixed with a suitable plant material (I have no idea what) from the aquaponics system, dried somewhat and then made into pellets, possibly it would work. It would be an interesting thing to try.

May I suggest fixing the mix. It is not just about plants but also your mineralization requirements.
