is sex reversal pleasurable to eiter the fish or the reverser?

I had thought about doing this using 4 x 4 metre tanks split in half so that you can get to the fish easier. I though 4 of those in a row on a small downslope so that the water flows into each tank and using the first tank as a filter and pumping the dirty water back into the filyer tank.
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.

Dalton

I can hook you up, if you wanna try...

Dalton

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

I mixed up wholesale and retail prices....duuhhh

They normally buy/sell them at 100 gms plus, but if they get to beer bottle size the price begins to drop.

Our fish behave like Pirahnas at feeding time now, one more month and off to market we go.

Next to Nong Luang lake south of Wiang Chai there is a fisheries centre we used for advice years ago re sex reversed Pla nin and Tap tim. We bought 1000 pink fingerlings and a few weeks later they all suddenly disappeared from our pond.

I know all about walking catfish but nothing about walking fucking tilapia

sabang

^ What about walking Thai with nets

Thetyim

I lost 100 TapTim to a single PlaChon fish.

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.

Did you know the average male is 6 inches long, and the average female is 8 inches deep? So in New York City alone there is over 3 miles of unused pussy!

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)

crabfat

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?

blackgang

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.

Driventowin

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..

blackgang

^ 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.

Thetyim

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

Driventowin

Yeah but BG they fling a lot of water.. Not a very beneficial result in small areas where you have to replenish water, they also induce more evaporation too, so from those points in small applications it is better to have a smaller aerator for injection with out so much agitation. I don't mind telling you that here in Thailand I would be highly dubious of the safety factor having one of those 220V motors suspended over the water like that with the electric having to be run through it as well..

My frigging microwave shocks the piss out of me if I ever touch it without slippers on or stand on a mat so I certainly wouldn't want to have any contact with something like this anywhere near water..

But hey I already suggested it before so I'm not entirely shooting it down either, I just don't think it is a good application in these smaller cases..

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,

Thetyim

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

Driventowin

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..

lom

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