^ What about walking Thai with nets

Given the above , is there an easy and cheap way of oxygenating the water if necessary?

Dalton has an idea but ideally you could purchase some spa jets and install them on a row of pipes and run the pump water through them, they in turn will produce an air injected system of fresh agitating aeration along with flowing water..

I have seen in the southern states of the USA in catfish ponds, a raft like affair with a double shaft motor and a set of paddle wheels on the shaft and as the motor spins it throws water in the air and churns up a lot of water and does a good job of aeration.

They use those aerators a lot in thailand for shrimp farming.

( Don't mention the USA one's again because the Thais think they invented it)

I have access to the moo ban water from the government but I think the tanks will need topping up on a daily basis. Do you think that would work? I have done some drawings in excel but due to my low number of posts I am not allowed to add attachments. Sorry.

You have the right idea, for small recirculation system, try to have a look on the thread called "my farm used for final project" there's some pics of the setup I have. You can email your drawings to me, I'll send you a PM wit my mail.

Cheers

Did that this afternoon.

My mate is telling me something about a government fish place at Bung Boraphet near Nakhon Sawan. Does it ring any bells with you?

Sorry, my bad....

But they use them also at the settling ponds where they have to treat water at the papermills in the North west before they can dump it back into the rivers.

I forgot about them, as I have seen them a lot up there.

Yeah this was what I was referring to when I posted about my trip to China in Dalton's other thread..But this is too elaborate and a bit of overkill for the smaller ponds being described here..

^ Why would that be so, it is cheap and does the job fairly well and not to much bother.
And seems that they already know how to make em.

Some thai aerators here.
Model RX7 only uses a single hp motor

sounds like you need 3 wire service in your shack and grounded plug ins,, I did that when we built this place, now no shoes and touch anything,, but we also wear shoes mostly or at least slippers inside.

But replacing a little water wouldn't hurt anything either, but we have no water well and can't get one so it better rain, and I am going to add more storage this year,

Have you tried turning the plug the other way around ?
Sometimes it stops that. Sorry off topic, carry on fellows

Yeah I know the polarity gets switched here all too often and the problem with turning the plug around is it doesn't work if anything else is plugged into it, because you get feed back through the other appliance, something is always backwards if you know what I mean? I don't own this place and it is common everywhere here in Thailand to have this problem.. This place is better than most they do have some grounded outlets but not every one..

Yes, 50 times per second. Or in other terms 50 Hz.

Are they actually grounded with a thitrd wire or are they just 3 hole plugins so you can not have to cut off the ground lug from the plugs, I have seen that and we have also bought a short cord 3 hole plug strip to take with us when we travel so the wife can plug her laptop in when we are at hotels,, but the cord in it is only 2 prong and no 3rd wire in the strip.

No chance of them walking away More likely some Plar-Chon (snake-head) left in the pond, did you see any dead fish ??

They are very effective predators..

They are used here in Thailand as well, mostly for shrimp farms through.

I have never been there, but each district in Thailand normally has a department of inland fisheries.

For shrimp it will work, but not really for Plar Nin, unless you start changing water and fight the problems with increasing ammonia and nitrite as a higher stocking density will create.

Wise arse...

Pla-chon...yep they're the bastard cluuprits.

We found several of them floundering outside the pond after heavy rains. Bigger than my forearms..2 Kgs +

They can jump/flip like buggery.

Yeah they've become a real problem in the States too. They can move from pond to pond out of the water for a period of time when their food source gets decimated, kind of like a walking cat fish..
