  1. Thanks for the responses guys. If this project ever gets off the ground, I'll let you know how it goes, including whether or not I think it's too Hannibal Lecterish for my taste. Keith, how do those crayfish work out? I'll have to look into those. I've thought about doing crayfish, but it's hard to find sources and I know that there is some concern about them becoming an invasive species. I have thought that it would be kind of nice to have something of the sort, and if they're working well for you, I might have to pick some up myself. EDIT: Ok, so Marmokrebs are an invasive species all over the place, although according to the article I read, there have been no reports of them in the wild from America. I still kind of want them, but I'm not at all convinced they're a good idea.
  2. I've read that the fat content in BSFL is too high to make a suitable fish feed on their own, so I've been thinking about experimenting with a combination of BSFL and other easy-to-farm insects to achieve a more suitable fat to protein ratio. I've also read that fish have difficulty digesting the exoskeleton of BSFL, but I wonder if that could be solved by simply running the BSFL through a blender and pelletizing them. I was just wondering if anyone has tried something like this before and if so, how it went.
  3. Hi Gary, Thanks for the suggestion, I'll have to throw that one into the mix. Now if I can get my funding and space issues sorted I might be able to make this thing a go.
  4. That's another good idea. Thanks! I suppose I should have just created a thread asking people for ideas for an easy to move AP system; probably would have gotten better results.
  5. Now that's an idea. I might be running a bit too shallow when the time comes to fit milk crates, but some sort of shelf could solve some problems. I'll have to think on this one. I'm still pretty sure I don't want to spring for hydroton, and I'm very sure I don't want to have to haul a bunch of gravel across the country, so I still like the idea of using at least some perlite or other lightweight medium, but an underwater support system would remove the pressure of needing the pots to float themselves, which would improve stability. Of course, then I almost might as well just do a styrofoam raft... This warrants some consideration. Thanks for the idea.
  6. Well, that's why you ballast with a bit of gravel. I'm not talking about filling these things with only perlite, and I am aware that lack of weight down low will tend to make things tippy. Anyway, it just doesn't look like I'm going to be spending more than a couple of years in any one location for the next few years, and I suspect that it will be cheaper and easier to just build a small system that can be packed up and moved relatively easily than to sell or trash the system and start fresh in a new location. Then when I have some more work experience under my belt and can start to compete for more stable positions I can build a larger, more permanent system and apply the lessons I've learned from the smaller system. I could just shelve aquaponics until I'm more stable, but that would pee me off nearly as much as the prospect of moving several times in the next decade.
  7. I haven't entirely sorted that one out just yet. I'm planning to put everything in a greenhouse, and that would give me some anchoring options above, but how to keep things upright is still a bit of an issue. I believe that something like lettuce or mint wouldn't be an issue, but that tomatoes could cause some difficulties. It's true that it's not a particularly advantageous idea. The idea is to use lightweight mediums to reduce weight so I don't have to haul 300 lbs of gravel with me if I want to move the system. I could just use hydroton, but my budget is going to be pretty low, so I need materials that are cheap and lightweight, so... perlite. I'm sure if I set my mind to it I could come up with some other ideas, but at this particular moment, this one intrigues me.
  8. I've been thinking of ways to make a system that would be too horrifically to pack up and move if I had to, and it occurred to me that I could make what is essentially a raft bed without the raft by making the pots themselves buoyant. I was thinking that one could put a layer of gravel in the bottom of a net pot to act as ballast, fill it nearly to the top with perlite, then put a layer of gravel on top to keep the perlite in place. I'm aware of some of the problems with this idea, potential for light infiltration, and just the hazards of working with perlite in a recirculating system in general, but I was wondering if there was anything I've overlooked, or if I might be underestimating some of the issues I know about. Thanks!
  9. Are all of your fish accounted for? I remember reading about Gary having some of his perch get into his drain, and some of them weren't found before they started to smell.
  10. Yeah, we probably have those over here as well, it just seems like there should be more efficient/economical options for a small farmer trying to get his animals to market. If I were in a position to even think about having animals to bring to market I would probably look into it myself, but for now I can only dream and hope that I'll have some room soon.
  11. All this makes me wonder: Is it impossible to have oneself certified to slaughter one's own animals for sale? I'm afraid I didn't fully understand what ande was talking about above, but it sounds like maybe you can in Norway. It just seems that if the hoops aren't that horrible, why not jump through them. I'm just curious. It might not be feasible, and I'm not going to look into it now because it will be at least a couple of years before I'm processing my own meat, but it seems like there should be some way around this. Maybe a local micro-farming co-op that gets itself certified if the restrictions are too rough for individual small farmer? I don't know, I just feel like there should be some sort of end-around for these things.
  12. I think Gary still has the right idea, I just wanted to shed some light on the pressing idea. University of Idaho has done one batch of BSF biodiesel, and they just baked them a bit and pressed them in the same press they use to press their oilseeds. I'm not entirely sure how the pressing process goes, but I'm sure there's some material available online if you're interested.
