Doing nothing at my job today i stumbled upon this:
Doesn't seem to be too hard to make one and would be a good thing for ERE.
What do you people think someone would need to create one of those?
This is amazing. Not sure how much it costs or if they'll even set one up in the US. I did end up signing up for the e-mail list of DIY materials. We would like to eat more fish, but the cost is generally prohibitive. Thank for the new info!
Obviously they have no trouble with raccons, fishers, weasels, eagles, herons, etc. that will raid ponds...
Here in the Pacific Northwet, you'd need bird netting at a minimum if you don't have 4'-5' water depth.
There's also the question of whether one needs a permit to keep certain fish species. Escapee non-native fish are highly frowned upon in these parts!
Here we don't have problems with permits, but my friend have an artificial lake and some birds appears now and then, but his fishs are bigger so that's not a problem.
But a net will solve most of the problem if some "WILD BIRD APPEARS" =)
An electrified fence is cheap and enough to keep wild animals away. Or two good dogs. But the fence is cheaper.
Just need to figure out how to build and maintain one of those things. I'll certainly have one in the future.
What about temperature extremes? Fish don't like heat or cold.
I think such a small system would need to be finely balanced (nutrients/microorganisms).
Some fishes can handle these differences better than others. I guess it's something you need to study before. In my city we don't have a lot of extremes. It's more hot than cold on most of the year so it's not a problem if you choose the correct specimen.
As i said, my friend has a lake and it's not that big. When it's extremely hot, the fishes go and hide under the little bridge. He got this lake for almost 2 years and we didn't see any problems.
Aquaponics solves a lot of the raised issues (nutrients and temperature are the two that spring immediately to mind, to an extent though!)
