Cheers RBH, wife has been doing a 70% change every 3-4 days and puts in a few handfulls of salt. It is a good point mellow and has been at the back of my mind too, haven't scrubbed the Schmutzedecke either it's a sort of emerald green rather than the light green of algae. The reason we did a 100% change is that we were without water for 4 days, the pumping station broke down.

wow, very interesting, entertaining and informative thread. thanks for taking the time to add all this.

Those are some pretty good water changes, how did you decide on that amount? Where your fish ready for Sonkran? Are the sales going alright for you?

Finally cleared out all my ponds, my first harvest since nearly 8 months of drought last year.

This are my result :

Location : Chiang Rai

Period : 1/9/2010 - 23/1/2011

100'000 Big Oui catfishes

Farmgate price : ฿40/kg

Total feed : 1346 sacks (Betagro's Omeg)

Total supplement cost : ฿3'000

Total variable cost : ฿3'600

Total weight : 21 Ton :shock1: ...

That is correct~ 21 Ton

RBH,

As always I marvel at your success. With Chinese New Year in the air, I suggest plenty of red and gold flags, balloons, sky rockets or whatever to keep your good business results happening. Obviously in your case it has very little to do with LUCK.

Actually IA, luck play a big part, combine with hard work and experience

LUCK = Rain and climate.

This season's lowest temperature was 12'C compare to 2009 year end cold season, lowest temp then was 6'C.

I am definitely marveling at this. I'm interested in setting up a fish farm myself, and found this thread as part of my research and still can't help to be impressed. Hopefully, I can get my small scale operation going. My grandfather has 7 ponds, 4 of which was given away, and now I have only 3 pond to work off from. This will be done in Laos, the central part, which has a more moderate climate than Chiang Rai. If you have any tips for starters and where to begin, please do share. I'm looking into setting up an aquaponic system if possible, where the fishie poop will be recycled as fertilizer to a floating garden of lettuce. I'm a little overwhelmed at the thought of what goes into the operation, but at the same time excited at the thought of trying out this sustainable way of life.

I'm an American who will be making my way to Laos, so there's lots to figure out. The wealth of knowledge you've posted in here has been great. Thank you.

you're most welcome...one step at a time. get the pond up and running then you could work on the sluice for the lettuces.

Getting the "fishie poo " out of an earthen fish pond would be like separating fly poo from pepper.

Mr RedBullHorn ... I'm really disappointed in you!

You never told me this Thread existed ...

Certainly worth a read for those who are interested in Fish ... but haven't read your OP.

Well done ...

Thanks David, it's been 6 years full time and many more ahead... I'm not an easily contended person, already an expension plan is in the pipe line for 2013 (if we survive "End of the World" ) Currently the 600'000 fishes/year is bringing in a nett income of ฿800'000+ ...... Hopefully with the expension next year will see me breaking into the ฿1mil mark that is been forcast.....

If you like video clips of the latest farm operation, please go to "clinton9938'' Youtube.

hello my name is mark i live in hang dong chiangmai i have around 1000 cat fish i need to sell

its the first and last time my wife have a fish form triying to sell fish she have no time looking after the form

if you can heip me with fone numbers to sell them round chiangmai i wood be thankfull the help thank you

The Chiang Mai wholesaler that i know of change his number...usually you could get the contacts from the people who sell the fingerlings or pellet feed. For you information, Wholesalers will buy your fishes if it is minimum a pond of 10'000 onwards. They can't be bother with 1'000. Advise that you tell your wife to sell them herself in the morning market, 1'000 fishes is about 200kg, will take about 5-7 days to sell off.

Mark, I live near Hang Dong, if you catfish are eating size, there are several markets you could sell them out of the back of a vehicle between you and Chiang Mai.

Just a thought, park on the outbound lane of CM hang dong road and you could probably unload the lot in a short time. If I see you I will stop and get a mess to fry up.

My first harvest of this year ( last harvest of 2012 if according to farming cycle with the calender starting on March)

Harvesting period 25-31/01/2013. 90'000 fishes, 18 tons. Size 2,3,4 and a little 5 fishes/kg. (about 10% roughly on the size 5)

Laughing to the bank (again)...

nice yellow tinge

Size jumbo, 800gm and 700gm ( about 5% of the total harvest)

RBH ... some great images there ...

Great to someone making some money Farming.

RBH,

You just keep on laughing!

Happy new year.

Sent from my GT-S6102 using Thaivisa Connect App

Finally the expansion quota is approved !

An additional 300'000 fingerlings, now all i have to do is wait for the pellet feed quota.

Once all the approval are through, I'll be doing a total of 535'000 fingerlings per season... 1.6 mil catfishes per year.

I'm trying to find out the recommended stocking of catfish for an earthen pond without aeration. Obvioulsy it's not for commerical purposes as I just want this for psersonal consumption. I've tried researching elsewhere but most figures are based on some form of aeration.

For pond size 400sqm (1 Ngan) at max water depth of 1.5m, recommendation is 10'000 fishes. (standard stocking rate)

>12'000 (over-stock)

1 Rai = 4 Ngan. Stocing rate times 4

Edit: 11'999 is still over-stock...

Thanks for that. I originally thought the figures you had quoted earlier were for an aerated pond because they seem densly stocked.

I was also wondering for a set up like this (or a smaller version), if you need a water change during the growing cycle or between cycles?

This thread is here already since 2009. I just discovered it..

Ouch!

I have a pretty decent computer but page 1 raises all red flags here.

Would like to enjoy it, perhaps changing the direct youtube links into hotlinks will allow me and others to access the first page?

how to change them ?

50% water change when water is foul during growing cycle, usually twice.

how to change them ?

I want to see them. Why not ask a MOD for assistance?

Dancealot ... the problem maybe at your end as they play A-OK for me ... both inside the first thread and when you click the YouTube hyper-link and they reopen in a new window.

RedBullHorn ... couple of things.

I have this recent thread about Fish Farm Aerators and would warmly appreciate your valued input and Videos there. fish-farming-paddle-wheel-aerators Would you post them there?

If your time is limited, but like the idea, would you like me to place them on that thread with acknowledgement to you?

If, however, you wish to keep your media in one central place I fully understand.

Let me know please.
