Best Fish for Aquaponics
Dr. Nate Storey: So a lot of people have asked
about fish. What’s an appropriate fish for my aquaponic systems? There’s several variables
that you want to consider. A, you want to look at the environmental conditions that
your system is going to be in, and match a fish to the environmental conditions. If you
know your water temperature is going to be high, then trout probably aren’t appropriate.
B, you want to look at your feed sources. You want to figure out what kind of feed sources
are available to you, and you want to match a fish to the feed source.
The last one is you want to find a fish that’s appropriate for the purpose. So if you’re
not interested in eating your fish, say you’re interested more in a mental fish, then something
like koi or goldfish would be a great choice. They’re very tolerant of poor water quality,
they’ll eat just about anything, and they’re very easy to take care of. If you’re interested
in a food fish, then of course you want to consider a food fish.
So keep those three things in mind. What are my environmental variables going to look like?
Does the fish I am considering match the environment? B, what kind of feed do I have available?
Am I going to use commercial feed? Or am I going to use some other on-site feed? Vegetable
matter, black soldier fly, whatever you have. C, what do I want to use the fish for?
So those are the three things to keep in mind when you’re considering fish. Beyond that,
just about anything is possible. So depending on those three variables, you could be growing
anything from catfish to koi to trout to tilapia. You name it. All of these fish can be cultured,
and are in different aquaponic systems in the U.S. and around the world.
All right, well welcome to our video tour of our greenhouse. This behind us is the greenhouse.
You can see the fish house here. We’ve got our greenhouse kind of heading on an east
to west axis there. It’s a double layer poly film inflated …
