line your pond or dam with plastic sheet  then lay rubber tires bottom and sides /holds plastic and 

crayfish live in them plastic stops them digging holes in mud  cheers allan

Thanks, I was thinking of something similar with a thick plastic tarp that is staked up 50cm around the whole pond to make walls so they can not crawl out. Do you have any experience lining a pond, if so how thick of a sheet did you use?

This was an interesting article on Thailands venture into the crawfish industry.

http://www.xinhuanet.com//english/2017-06/08/c_136350638.htm

Yeah another scam what a surprise. I just pay for what I want, never sign a contract or make any agreements and sell to whomever has cash. As I tell my business partner (the wife ????) our business philosophy is KISS (Keep It Simple Stupid) - yeah it took some explaining to convince her I didn't mean her - LOL.

From the article "The prices of ornamental crayfish usually start at 100 baht each" so maybe these weren't suppose to be the eating kind. The ornamental one's are 40 bht each in Chiang Mai incl. the all white ones. 

Also it states "matured crayfish at a price between 400 baht to 700 baht (11 to 20 U.S. dollars) per km.", I wonder how many crayfish it takes to make a kilometer long line of them .... yeah I know they meant kg!

For shrimp I thought a pond dug out of the ground with a plastic liner was more common?

 

The depth is critical - too shallow are they get too hot or eaten by birds, too deep and they are difficult to catch, and the lower levels can become deoxygenated.

 

I also hear that over-feeding can be an issue, as it depletes the oxygen in the water.  Also disease risk from the seed stock, and from birds?

 

But when done right - can be a good business.

 

I'm not sure if it's true - but I was told that for simple, small scale - you add Tilapia to the shrimp pond, and they help control disease?  May be farmers folklore though, as I was told this over a Leo.

 

Sorry no idea what is common, I've never seen shrimp grown in a pond.

The pic is what I tried, with the 50% shade cover to keep the temperature down and birds out as you mentioned.

I've also heard of keeping fish in the same pond as shrimp.

Thanks for your words of advice, I need all I can get!

There seem to be some inconsistencies in your numbers. One talang wah is 4 sq.m., so is it one crayfish per talang wah or per sq.m.? And if it's only one crayfish per talang wah/sq.m. (in your earlier post you mentioned 10 per sq.m.), your 5 sq.m. tank would only hold either one or five crayfish. 

Yeah sorry mistook Talang Wah for Sq mt, it's 10 per sq mt (I've been told) so would be 50 total (5 mt x 1 mt = 5 sq mt x 10 = 50)

 You did quote me  "1 sq mt (talang wa) per crayfish so my 1 mt x 5 mt tank " so my mistake is fairly obvious for someone who knew

What benefit does concrete/cement/brick tanks have over plastic kids pool type tanks ?

I expect either is fine but I was advised 1 sq mt (talang wa) per crayfish so my 1 mt x 5 mt tank would only hold 50 or basically one nice feed of a crayfish boil (I use to be a Chef in New Orleans) for my family. So I figure plastic pool would be too small for my purposes and I'll build a  rectangle tank along the side of the building I use for my worm farm (see attached pic) would be a better use of space. If things work out I can then start raising them in the pond right next to it. Actually I stocked that pond with 350 Freshwater Prawns and never saw them again so will need to figure out that issue before restocking with anything besides fish. There are some tilapia in there now from when we had a flood and Pla Nin from my big fish pond ended up in there but I'm also considering catfish as I just found a buyer for them locally.

Thanks seem license needed when not native

they also got YT channel

 

Thanks turns out my wife has been following that channel (and I didn't even know she watches Youtube!) 

License makes sense. 

I expect one isn't needed for a few in a home aquarium, they sell them in pet stores here too, so wonder where the line is if I only have a small number and not selling them or raising in a pond?

Will check into it and try to find out.

All the Thai's around me who put in concrete block tanks to raise them have got rid of them.

I guess the shine wore off paying Pet prices to get breeders then growing them out and not getting the returns they thought.

You may have to check locally if a license is required to raise them.

There are plenty still raising them in Thailand,most of the info will be found on facebook.

I plan on trying in concrete tanks this time, thinking 5 mt by 1 mt by 60 cm deep with 2 monks to partition into up to 3 separate sections with a total of 50 Shrimp or Crayfish (10 ea. per sq. mt.). 

I can buy at a Shrimp farm for 3 bht ea. and Crawfish 5 bht each. I've seen Crawfish at Kamtien, the big garden market in Chiang Mai, for 40 bht each intended for home fish tanks (I hope!). 

No idea or ever heard about a license but as I'm raising only a few for personal consumption I don't think it will be an issue, same goes for being concerned about financial returns.

Do you have links to any FB pages you referred to?

i have been thinking of doing same, as it seems pretty straight forward
on small scale, not commercial scale

I haven't found many of the farm projects I've started to be straight forward but enjoyed the learning process. My first attempt at Shrimp farming failed miserably. On the "expert" advice of my shrimp supplier I put 5 kg (aprox 350 shrimp) into my pond and never saw them again. 

Want to raise shrimp and crawfish on a small scale, any advice?

Let me explain it in a simple way;

 

I am asking if/how someone can watch TV in the CM region by using a system that normal people would understand as NOT requiring a desktop/laptop PC or smartphone or other similar device connected to the internet.

 

If so what equipment is recommended?

 

In the old days it was called a TV and an Aerial which came over the airwaves. Now that analogue has disappeared other pieces of digital (not necessarily computer/PC) equipment(s) are required.

 

In plain language:  I am asking on behalf of a non computer literate friend/no computer available;  Is there a system available in the CM region to watch TV (Thai only if that is all that is available but English would be a bonus) without the use of a PC, smartphones or smartarse comments. 

 

I accept that Electronics, including Boxes, Aerials, Dishes, cables etc may be involved but do NOT want anything connected to the Internet or Telephone/cable systems.

 

I hope there is someone in the CM region with a constructive comment, either in the affirmative or negative, who can assist!

 

Equipment, source and price if available would be very helpful.

 

 

 

 

 

 

 

To be honest "normal person" who puts any effort could understand how to figure out an android box, many you just plug in if you get it already loaded. I'm old and not into computers but can load apps on my box etc with a quick search on youtube. Do you still start your car with a crank on the front?

Out of curiosity, why? You like cable tv dish antennas?

 

I know zip about android boxes, whatever -- but I do have a nice, fast  3BB internet connection to my house. And I have a cheap laptop that receives 3BB hooked to my TV, whereby every US broadcast I can imagine can be received by my laptop and forwarded to my TV (yeah, Amazon prime video requires a VPN, but no big deal).

 

Anyway, I didn't subscribe to 3BB for this -- I just wanted a fast internet connection to my Desktop PC. But, the serendipity is -- my TV gets all I want from the US. Can't imagine why a cable alternative would be better (unless, maybe, you're located in a "slow" 3BB coverage area...).

 

Again, just curious -- as maybe my low knowledge of tech has me missing something....

Interesting I use Amazon Prime w/a VPN (maybe because I have a Firestick?)

Actually lately the VPN isn't by passing other restricted channels like before.

Wondering if the Thais censure "R" rated programming like HBO is likely to show?

Not sure but I have a subscription to Netflix and though some of the programming is different in Thailand and USA (I can watch either by using with or without VPN) both get 18+ rated content

I pay for HBO Max and as it's not available here I watch it from America on my laptop with a VPN.

How can I watch it on my TV?

I have an older Samsung Smart TV but it doesn't have HBO Max app.

I also have a Android Box but can't download the HBO Max app in it as says not available here.

Thanks for help.

Why don't you put a couple of them on a scale?

I don’t live near Nam Sai farm.  Do their figures sound right to you?

Nam Sai Farm.

Do these figures taken off the Nam Sai Farm website make sense?

Swim-up fry .008 -.009 g ea.

1” - .02g 

I calculated my 2.5" fish to weight 83 g each

Good luck with that.

 

My gf convinced me to buy a pond and fish and fish food and and and a couple of years ago. In the hindsight she hadk            c too many fish in the pond, they didn't grow the way they should, the food cost was more than anticipated and the highlight was when finally she was about to sell the fish someone stole them...

 

It seems you did already lots of thing a lot better than my gf did. I write here to warn you that hopefully                                   coyou will be able to sell your fish and make money with them. Good luck!

Thanks, luckily it's not a serious business for us, just something fun to do. So far so good, we stocked with the lowest recommended number of fish and the area is totally fenced in, has two dogs on it and my Mother-in-law and Sister-in-law house is right next to the pond. Already going thru quite a lots of food, a 20 kg bag every 4 days and am interested in what the final figures are after selling up.

There are a number of factors that determine if a 'fish farm' will be successful. Firstly - absolutely essential - is there enough quality water constantly?

 

Secondly; the fry. There is fry and there is good fry. A good strain* of pla nin will, after 6 months, be 100/150 gms bigger than the government supplied ones.

 

Thirdly; feed! After the initial cost of constructing the ponds, fish feed will be the major expenditure. There are a couple of ways off reducing the costs of feed. Nin can be trained to eat vegetable matter. Of course, this vegetable matter has to be either bought-in or produced by yourself. If you do it yourself you would need a shredder, and a supply of raw material. But it is worth it.

 

Don't think that people will not help themselves to your fish. Security is a must. To what degree; depends upon personal circumstances.

 

Another way of greatly reducing feed costs is to put feeding stations around the main pond, and feed with natural food.

 

* The finest fish available in Thailand. PM me for details.

What do you mean by "quality water constantly"? Our pond is full and stays that way with rain but we have a moat next to it connected to a valve and the moat is connected to the village klong the same way.

Did you put a rubber liner, or use concrete?

 

We're in the early stages of making a pool to keep fish, but not to sell.

 

Keep us updated, please.

????

Neither, it was a rice field and we just dug a few ponds and a moat and used the dirt to bring the ground level above the water tablet as seen in pic above.

Are they alive? If so meant to be grown more or ready to eat? 

Hi, brand new member to group and I want to start a fish farm. I'm in Chiang Mai and have a 20mt x 10mt x 4mt pond full of clear looking water which I'd like use for Tilapia. I don't know anything about the it but have locals who offered fish, food and service (delivery and pick-up/purchase). Any and all advice appreciated. Thanks!
