Backyard Aquaponics
A place to discuss aquaponics

Sounds good.
but, to be viable in the commercial side of aquaculture/aquaponics the feed must be cost effective/affordable. If too expensive it will never work on a large scale. Unless the customer will pay.

For Instance, the commercial catfish industry is taking a major hit this year with high feed and energy prices. Lots of folks are just quitting.

It's happening all over the world jdphish, here too the fish food prices have gone higher and higher. We'll have to find a way of producing freshwater fish meal for fish food soon.

That's not much supplementing is it? I've honestly never seen the stuff other than a picture of a bag of kelp meal on a website. 50lb for like $54 or so. Is that high for a feed supplement? I'm thinking this will add to the nutrient value of the fish effluent but insects, worms and other readily available natural resources might be just as well. I'm surely no feed expert, just random thoughts.

On a docco i saw a while ago, they stated that insects were the most renewable source of protien....

so maybe an algae and insect meal pellet?
