Has anyone found a source of feed for their tilapia that doesn't have fish meal in it?  I"m not having any luck finding anything I consider sustainable so far, and I'm too busy / lazy right now to start up a duckweed system.  Thoughts?

@Rick - Most crayfish are herbivores and need plants or algae to eat.  They are also scavengers and will consume dead things, but they don't literally eat 'crap'.

@TCLynx - yes, in order to really emulate nature we need a lot more space than we're comfortable using in our little tidy systems.  Some hydrologic and ecologic cycles only work at certain scales and need a minimum volume or surface area to be effective.  But it's a fun challenge to see how much we can condense those functions down into our backyards!  =)

@Carey - yeah, great stuff.  I had read that thread before, but was trying to keep this thread more focused on commercial feeds you could purchase.  I personally lean more towards natural solutions whenever possible.

Back to my earlier post about the more natural feed I purchased from Foster & Smith......

Since I started on the new feed a few weeks ago I've noticed my plants really starting to surge!  Growth is dense and luxurious with none of the signs of deficiencies that I was plagued with before.  I might just be imagining things, but it also appears that the plants are more robust and better able to fend off the aphids.

Good Quality Feed makes a huge difference.  Can you re-post the details of your new feed for us Averan?

'good' and 'quality' seem to come at a price, in this case, about $7/lb.  Note the 40% protein content and that the ingredients are mostly two-word minerals and vitamins or words that you can actually understand.  It's not a totally natural feed, but seems much more wholesome than the ingredients in a bag of cheapo big-name brand.

Wish they were more specific about exactly what the plant proteins and animal protein products actually are.

Oh well.

 

good to hear you are having good results with it.

i know!  that's always a bit of a warning sign...when manufacturers hide ingredients in generic terms like that.  i had to compromise a bit as i wasn't willing to afford the 'miracle koi food' that seems to be the only fish food made from only natural ingredients.

compared to the PondCare koi food i tried previously, this stuff from F&S is dark and rich looking/smelling.  one of the biggest differences in the ingredients is that the cheapo brands are mostly made of fillers like 'wheat flour' whereas it is the seventh ingredient in the F&S stuff.

Way to go Growing Power!  Just make sure there's enough protein content in what you're feeding, and throw in a little at a time because whatever the fish don't eat will stay in the tank or gunk up your filters.  (Oops, just noticed others are saying the same thing above...well, I guess I'll just add to the chorus!)  Also, I've heard that sometimes it's hard to get adult tilapia to eat this way when they're used to eating pellet feed.  But, if you start feeding the young ones this way from an early stage, you won't have a problem.

 

Also, I'm in the experimentation phase of making sustainable pellet feed.  I'll keep everyone posted on my progress!

 

Good luck, and it was great to meet some of you at the Conference!

Love all your ideas, David! Can't do soldier fly here...too dry in Colorado, but I want to try the other two. Just found out yesterday that at Growing Power they feed the tilapia scraps from the salad greens harvest during the week, and only resort to commercial fish feed on the weekend.

Also, Duckweed is grown a lot for tilaipa...here is a link to an amazing article on it ...http://www.fao.org/Ag/AGAInfo/resources/documents/DW/Dw2.htm

Hello 

I came across this video.

Is anybody experimenting this on his system?

Anything working out with feeder fish or shrimp?

I'm hoping I can get a shrimp colony going in my raft bed and scoop from that to give my catfish/bluegill some treats.

Nope, nothing new so far on that front George.  But I am watching for the Organic fish feed that Patrick has teased us about.

I'm looking around.  The thought of ground chicken feathers being in aquamax really bothers me but outrageous shipping costs bother me too.  I'll likely try some feeder minnows or shrimp at some point, once the bluegill are big enough to eat them, mosquito larvae too when warm enough.
