Hi, I'm interested in raising goldfish for less than $1/lb, and so obviously purchasing fish food is not an option. Do you think that a diet consisting of BSFL, duckweed, red composting worms, and peas is a healthy mix? I've been reading about how someone feeds his BSFL with horse meal ($8 for 50 lb bag) as well as food scraps, then uses the larvae effluent to grow duckweed, and uses the larvae castings to feed the red worms. I could grow the peas in regular old dirt (fertilized of course with the castings).
Thanks for your opinions on this.
Well, forget Skretting if you're just looking for cheap. Shipping for 40 lbs is about $60 to my place.
Skretting.us has a downloadable brochure about their company and sources.
Thank-you all for your input so far. I've already contacted my local feed store and they are a Purina distributor so they can get that feed. For the moment, I'm just using aquarium goldfish flakes, because I just set up my AP system and the fish are pretty tiny. To clarify, my goal is to spend less than $1 to produce 1 lb of goldfish. That means the feed should cost a good fraction less than $1/lb, since the conversion of food to goldfish flesh is less than 1. The reason for this goal is that I help to rehab wild seabirds, and currently we buy smelt that is $1/lb, and I'd like to set up an AP system that can compete with that. So, I'm first building a small demo system, but then if I can demonstrate it can be done, then I'll expand it.
I'll definitely check out those low-cost commercial feeds that have been suggested, but really I'd like to make my own food, and am trying to determine a healthy mix. I also live near the sea, so have easy access to seaweed (giant kelp, etc). So, I thought the following mix would be healthy: peas, seaweed, duckweed, BSFL, and red compost worms. Maybe also some spinach leaves, grown in the AP system itself.
Thanks again for your help so far!
I say go for it Eric. Try out your homemade formula and let us know.
I'm new to aquaponics, but I've been doing some digging on fish feed, I stumbled on this article http://edis.ifas.ufl.edu/fa097 . They do a good job of breaking all the ingredients down, and even have a few recipes, It looks like a lot of work, but if I had to pick a recipe to start with, the last one in the publication (gelitin based) looks like it the easiest to put together, not saying I'm going to do it, but its a informative article on fish feed, worth checking out.
