I sure do like to eat shrimp, though, so still considering it.

Like all things which can be cannibalistic, if they are well fed much less likely.

I also think if someone was inclined they could look for and choose less aggressive shrimp to selectively breed a better to culture prawn.

I would be happy to raise 10 pounds a year. Don't think that will happen in a hot tub though.

Another product that, if you shop sales, can be had relatively cheaply. At $7/lb, cleaned and pre-cooked, it would take a lot of shrimp to make up the difference.

One site I was reading on said you can either screen them off into sections (but they didn't say how) or keep the water too turbulent to allow them to move freely which prevents them from hunting each other.

Crawdads would probably be better for small scale aquaponics.

Crayfish are similar in the cannibalistic thing. perhaps more so as they are confined to one plane of the water body.

I would really love to raise RedClaw cray fish here but seems they are Illegal to have with out special permit.

You might try the self cloning crayfish, MARMORKREB or MARBLED CRAYFISH
Since they are self cloning they really only eat each other if there isnt enough food. Ive had dozens in a small tank before.

They dont get TO big, but they get big enough you could eat them.

you need to go find yourself a good koi pond forum. There are tons of DIY ideas out there for koi pond filters. Fish that are growing fast eat a lot ond produce a lot of waste. The waste must be mecnaically filtered out and also biologically filtered (to eliminate ammonia). I have kept koi for a lot of years and let me tell you, it's expensive and hard work to do it right. I designed and built my own filtration and my newest design uses airlifts to move the water rather than a big koi pond pump. Its cheaper to buy and to run an air pump. Auqaponics is a great idea if the growing season will permit you to keep a veggie crop on top of the water because the veggies will handle the ammonia.

Crawdads are actually much worse.

I don't think it is because they are hungry. I think that they kill each other because they are territorial. There isn't much you can do about that except to keep them separated or give them enough space.

It isn't a problem with the salt water prawns, but to raise them, you need sea water in addition to correct temperatures. The thought of getting the environmental permits for that project makes my head spin.

If someone comes up with a freshwater prawn without claws, it might help the cannibalism problem. It's not going to be me. Breeding shrimp isn't on my bucket list.

Crawdads may be worse about eating each other but I can get the starter stock for free. Got a small creek on my property that has some crawdads in it. Or I could pick some up from Mom's creek or ponds.

Just remember that's usually frowned upon unless you get permits for wild harvest.

Not saying it will come to light bet it could.

From what I could find you cannot move them from one body of water to another and you can't possess more than 100 without a bait dealer license.

They are commonly used as bait all across the state.
