I've only seen them after they're full and those were in ground. There was one man who owned a nursery and set up a series of small tanks that the fish somehow swam from tank to tank through shallow lined chutes, but as to any detail...
Phicks are you planning to recirculate your water to feed plants and clean it? I've often thought that my water beds, vegetables/flowers could be great with fish water circulating through them. If nothing else, you could grow duckweed for compost. Your # of fish is going to depend on how clean you can keep your water. Aquaculture is getting hot because we've killed a lot of the natural fish populations. Talapia, striped bass, crawfish and prawns are all fresh water candidates.
You could call your extension office for literature or find it online. All the Gulf states are big on aquaculture.
Paul -that's exactly what this man did. He had greenhouses and water plants. Did fairly shallow pools if I recall( I'm thinking the deepest was around 42''), and may even have had some of the transfer chutes on typical sawhorse type supports. Because he had incorporated a great number of differing levels, I'd say he probably didn't have huge trouble with pumping --there was a lot of fall in there - slow, but there.
Yes, here also. There was a man who recycled his fishwater through a greenhouse to grow hydroponic plants fertilized with fish water. The local agent who told me about this said he eventually abandoned the project because of the resistance of the other fish farmers who just didn't like the idea. The man moved his operation to Tuscaloosa.
Paul, Brown is what's recommended. There are two brooks on the property, supposedly with native brookies, plus the beavers have made several large ponds at the end of the field, new since last year. We haven't tried for the brook trout, but wouldn't it be great to have a pond full of trout for protein?
I can't imagine being able to slaughter farm animals, although I'd like to have chickens for eggs and bug control. I guess I will have a retirement coop for the old ones, where they can sit in rocking chairs and have tea!
I was talking to a w oman who's husband died of cancer. To make sure that she would always have an income, he invested all his estate in fish ponds. She said she was so grateful that he had the forsight to do this. She said they do require round the clock care. The pH has to be monitored constantly. She s said on some occasions she has to make trips at night t o make adjustments. If you didn't care for them properly you could wind up with a pond full of dead fish.
So it is not exactly a "carefree" enterprise, but it can be very profitable - at least the catfish here are. But then there is a ready market for the catfish.
Gloria, I would think trout would find a good market, too, but I'm not looking for a business as much as being self sufficient. I would think you would want to avoid overcrowding, and I'm thinking if it's spring fed it would stay cooler and cleaner than it might otherwise. It's an interesting project at any rate.
I hope more people will post here if they're attempting it!
