Hi TD members.

I have started this thread in hope of that some of you might consider to try doing some fish-farming, it can be a nice hobby and doing the right things, it might also provide an little extra income.
So if you have any questions or ideas, then please post away

Cheers

Dalts.

OK, we are short of water for the last 4 or 5 years since the weather has changed, what do I do if I don't have enough water from rain to keep my pond full for my fishes no more??

Dalton

Do you have ground-water source availible ?? If so that can be used, provided that then water in your pond dont drain out to fast. If it does then you are limited only to raise fish during the raining season or you can put a liner in your pond to hold the water, you then need a lower stocking density of-cause. There's ways around water-shortage, but it costs money.

I'll try to be concise.

If the pond has stagnant water that is not easy to refresh, and is only 1.5 metres deep, what is the most productive fish to farm?

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

Dalton

My choice would be cat-fish (plar-duc) they are very resistant to muddy low oxygen water, after they reach 40-50 grams, before that stage they need better quality water.


You can use a small pump to make a fountain, to get some movement and oxygen into the water.

We're getting a modest house built near Ubon, and are planning to put a fish pond in. Mainly just to supply friends & family, and for me to do a spot of fishing when I'm up there. Not much else to do, except drink.

Thetyim

What would be your second choice ?
I don't want to do catfish

Dalton

Second choice would be Plar Nin, but that will involve some water-change, even if you use a pump to create oxygen, and you would need to keep a low stocking density (not more than 1 to 2 fish/m2)

Thetyim

Thanks, I am way overstocked then.

The problem is that Pla Nin breed so fast
Every couple of months an extra 300 fingerlings appear

Dalton

You need to use sex-reversed Plar Nin, if not then they will only breed and not grow...

Thetyim

Well as I am way overstocked I could remove all the Pla Nin which would leave me about the correct number of TapTim.
Do TapTim need to be sex reversed as well?

CharleyFarley

Up here in Chiang Rai, the cuurent liveweight price per kilo for catfish is 60 Baht

blackgang

No ground water available, Fil drilled down to damn near 600 meters and no water, I drilled down in another place 160 meters and no water.
The pond was dug by the govt on family land to supply neighbors with irrigation water, but has since been abandoned and turned back to family, who still let folks get water for irrigation, and thats what happens to the water, but before the drought set in we still raised a few thousand fish a year, but now it just gets to damn low and drys up some years, plus Fil died.

Dalton

No need to clean out the whole pond for fish, and the get your new fry or finger-lings from a source who supply sex-reversed Plar Nin and Tap-Tim (I can help you in that matter) There is no point messing around with the ones you have, since they are mixed sex..

Dalton

Tough enviroment for fish-farming.......Not any easy cheap solution to that problem, cant fight against mother-nature...

Dalton

What size is that ??

Thetyim

At what age/size is the sex reversal done?
I am pissed off that none of the "thai experts" that I spoke to told me about this.
How can I tell if they are all male or not ?
Does the price increase ?

Dalton

From day 1 and will end when they are 23 to 25 days old.


What to exspect....How much did you pay per fish ??


You cant at that age, you'll have to trust your source. The price for male fry plar Nin is around 32-34 satang and 42 for Tap-Tim.
