Fresh Water Prawn and Crawfish Farming

[JonBikeBoy 18]

Want to try raising shrimp and crawfish on a small scale.

Any advice?

[patman30 294]

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

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 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.

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?

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

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.

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.

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.

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.

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

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

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!
