What are your thoughts?
Alder Burns wrote:The ultimate beauty of the silver carp, especially, is that it is a filter feeder, raking plankton with it's gills and using that as it's primary source of nutrition. If the water is fertile enough there is no need to feed them anything, and they will grow to a large size. A system based on native fish usually relies on a small filter feeder or plankton feeder and then a predator fish that eats these.....with a classic food-pyramid loss in efficiency. Except for a thing called the buffalo fish, about which I know almost nothing, North America is missing large filter-feeding freshwater fish.

oh yah.... a little controversy! ... what are the other options? spin your intention around to maybe find other valuable designs....
put energy into growing azolla whose space may be shared with other water space based foods - I mean - isn't duck a higher quality food than an invasive species with lost of bone and little meat?

Duck is a high quality food with its own value, but isn't diversity one of the pinnacle points of Permaculture? Local to when and all that.
Besides the invasion of Asian Carp is the result of people taking advantage of river systems to breed these in cages when they're known jumpers. I'd only advocate this sort of aquaculture that was at least a kilometer away from any streams/creeks. Responsible rearing in watershed disconnected ponds or indoor systems doesn't release anything into the wild, invasive or not.

Probably a bit like canned salmon, bones and all, not my favorite but supposed to be good for us
I'm guessing that it was done during poor times here as a way to get through the winter with some diversity.
only difference between canned salmon and carp is the thickness of the filet... and flavor, I'm going to presume. Great point about what point people decide to go to that place. Uruguay has a solid diversity in meat types for daily diet. Here, if I had to set up a full protein producing cycle, I'd start with azolla... If I lived somewhere else where meat diversity did not exist, but I had access to sourcing diversity, I'd start with azolla... if that access did not exist, I'd start with azolla... (yeah, sounds religious..)

As for your Azolla thing... it doesn't sound very diverse at allOne big Azolla virus sweeps through your systems and the foundation of the whole setup crumbles beneath it.

Alder Burns wrote:I had azolla in Georgia, and yes it did collapse after a few "flushes" where it covered the surface of the cistern I was growing it in and I skimmed most of it off, only to have it grow back in a few days. Then suddenly and mysteriously it all turned purplish and quit growing. Research turned up the tidbit that it is actually quite hungry after phosphorus, and good continuous yields almost require some form of phosphorus supplementation. Otherwise it turns purple and quits. I had filled the cistern with creek water and probably the azolla simply used up the phosphate that was in it. I tried adding bonemeal and even detergent to the water to try to add some, but it never came back as vigorously as before. Eventually I gave up with it.

A guy had a small pond with some desirable fish he had stocked (bass, I believe) and some undesirable fish. Probably carp.
He spent part of a summer aggressively fishing the carp out with every normal and unusual method he had access to that wouldn't kill his bass (in other words, everything but dynamite).
Every carp he caught, he threw onto a raft. They rotted in the sun, and the flies came to turn the carp carcasses into bass feed, which crawled happily off the edges of the raft into the water.
At the end of the summer, the carp were gone and the bass were fat.
How's that relate to aquaponics? Heck, I don't know. It just involved carp and "the problem is the solution." So maybe it will jog somebody's thoughts in a helpful direction.
