I am going to be raising Channel Catfish and probably Yellow perch to start out with. I have a mud pond on my property and have already stocked some in there. Both are natives here in Washington and readily available. The primary issue is still heat. If the fish arent warm they dont eat and if they dont eat they dont create the waste necessary to feed your plants. They are more forgiving in this area should you have a power outage or some other reason for the water cooling. Trout like cooler, clean water, and need to be watched closely for health issues in high densities.
I am in the process of doing this right now. We got a cold wet start to the Spring/summer, and I now wish I had gotten an earlier start on the aquatic plants here. I do know that this can be successfully done though with what I have accomplished so far.. I am now successfully feeding our livestock what I am growing (duckweed is one of them) in a separate pond just for aquatic plants cultivation. I'll have a head start for this next Spring since I now have the "kinks" worked out of the cultivation issues . SO far I can use all I can grow right now. http://www.fao.org/Ag/AGAInfo/resources/documents/DW/Dw2.htm ( a Duckweed PDF ) was a good source of information as is a website called Bioponica. It helped me work out a few details. I'll be growing the aquatic plants as long as possible this season, and over-winter what I can. The Bioponica site may be helpful for growing feed for yellow perch too - read the stuff on and watch the clips on the "Incubator".
My best you you in this, and welcome to the world of aquaponics!
You are right about the bugs and smaller fish with yellow perch. That is where the "incubator" from Bioponica comes in....I have a version of that going too. Just thought that the places for you to find info. might be of help to you. Best to you!
Hello, I am new to this site, also in Oregon and dealing with what will be optimal to grow. My wife and I are planning on Catfish pond and Crayfish pond, with seperation or at least major hide spots for the crayfish. Its great to know about drying the duck weed- our ducks eat all of ours so far though. They love it. I wanted to have the ducks on the same system as the fish however I know that warm blooded creatures can pose serious health issues with this- hence the no manure in a aquaponic system. I couldnt understand a word on that Bioponica site... I plan on just using my duck/chicken/rabbit manure for adding nitrogen to our compost pile and getting it nice and hot- which it is, i need to go flip it, get it mixed up so I can actually use it in a couple weeks to a month, however probably just gonna let it age over winter and use it for planting in our soil garden area. I actually was wondering about the use of the compost pile though to help heat the ponds? I could imagine having tubes run under a pile, has anyone else considered or attempted this?
If you run a constant composting system, you can take advantage of the heat that it creates. A simple method would be to form a loop that runs throught the compost pile then throught the fish tank. I would make this a seperate system, meaning, I wouldnt run the fish tank water throught the compost pile. Have a seperate reservoir tank, pump, and you can use the black water pipe that comes in 100' rolls. Loop this through the the compost and and lay a coil on the bottom of the fish tank. Make sure the reservoir tank has a breather cap so the system isnt air tight. That will prevent any pressure build up.
