We should start producing e-books from what you are dredging up. Some can be updated as we have learnt but there is a load of stuff I had forgotten about.

Is there any differences in cultivating pha nin and tubtim? Is one harder to cultivate than the other? And are prices for them different?

[ray23]

I think this year I will cut back on commercial fish feed with our Pla Nin. Again following Aussie Don. only way to really find things out is give them a try. As one shoe doesn't fit all.

Cultivation is about the same, tabtim demand a bit higher price in some areas but they are not as hardy as Tilapia, you can grow them together.

Thais will not pay extra for them in the village markets so we dont bother.

Thanks, good to know.

Sticky Water In Fish Tank

Read through it we did a small one to hold the fish for sale. Three days is it or they die. So we just put them in wehn we have orders. Talking about Plan Nin.

We have been trying to find Cat Fish fry for sale foor about three week in hte Udon area, b no licj so far. We know a supplier tyhat we used in the past. But, he doesn't seem to be able to get any out on Bangkok these days. Lat time I ran air into the pond this time when I ge them I will not o do that and see how things work out. Since the v crotters like walking out of a pond we will fence it to keep them in. I'm also going to place a ligh about a foot above the water and try to attract bugs to cut food costs down.

Anyone lese feel like your in a big experiment

[RedBullHorn]

During the bugs season (near Monsoon period)... they contribute 5-10% of the total FCR.

Black light (UV Tube) is a must !

RBH ... I hate to add to your workload ... but any chance of doing a separate thread on the use of the black light attracted bugs supplementing the fish food chain.

Or, if your time is limited, maybe a brief summary here?

I did some research and some said great ... some poo-pooed the idea.

Obviously it's working for you ... so if it's not a Trade Secret, care to share?

Your the second source on that outstanding, I will give it a try if I ever get some fry. Must have been a heavy demand anyone else having trouble sourcing them?

A great % of the villagers have a "black light "setup, mainly to supplement their own food, by the time the family take their share there isnt much left for the fish and ducks.

The crickets and assorted beetles are to valuable cash wise to get down the line as food for the fish etc.fried crickets are bringing 20- 30 baht per 100 gram.

[IsaanAussie]

Do not know about the crickets and beetles but Black Soldier Fly larvae contain an organic acid that has been proven to reduce mortality in fishponds. This acid knock out various pathogenic viruses and fungii. The larvae also have a high protein value that is an alternative to fish meal in feeds. I would be pelletising catfish food today if I got get my hands on those guys.

[ray23]

I would guess good protien in moast bugs and cutting down food costs will really help the bottom line.

Too bad that thread got archived, I would have bumped it. I am running 4 cement tanks and have no smelly water issues. But I have some homemade bio-filters that keep the water on the sweeter side. Still experimenting though.

Well when you have time post what yuo have done sure would like to use my holding tank more then three days. We use a double filter system white pads. anything past three days fish are dead. Try to do it with some fry, to get them to a better size before putting them in the floating nets. Just to do that I had to change water everyday. That get's real expensive real fast. So the little guys are in the floating nets now. I plan on releasing them into the main pond when the rain water fills the pond again. Sorry should have mentioned these are Plan Nin. I will google this and see if I can get some more information. But, hands on experience is much better.

Well I am going to be on the road tomorrow, but if I get back in time I will take a few pics and try to explain what I did. I am running Tab Tim currently.

I read that quickly canuckamuck ... and read ...

I am running Tim Tam currently ...

Even though I'm the OP ... I'll get my coat!

[ray23]

I reviewed the stuff on Google to compare with what I'm using now. The biggest thing I noticed is they are filtering from the bottom up. Mine is just the opposite. I imagine won't be that hard to change things around.

Did mention something about using carbon. In the other thread it talks about using salt.

I really think it would be best to consolidate into this thread as this in Fish Farming 201.

I was cricket farming back in 2008 just to supplement the fishes, i bought some cricket eggs for ฿600 then bred them in big concrete ring. Very easy set up with rice husk as bedding, commercial chicken feed as food, water melon and maize as side dishes. If memory serve right, it took 45 days for the collection of their eggs then expand to another concrete ring and another then another... i got a total of 13 rings ! but still not enough to feed 120'000 fishes back then. The crickets have to be collected and put into a sack for the purpose of terminating their lifes and then sun dry.... At the same time during that period i was experimenting a certain formula to concoct a supplementary booster for achieving better FCR, when I've finally got it right, i ended the cricket farm and set up black light (Ultra Violet light tube).

In the morning, the wife will come and collect the edible ones and happily scoot off... the rest i will just feed them to the fishes. This are the ones she can bag (under the black light), while individual pond have their light above the water 2m out from the dyke, the fishes got them.

Oh <deleted>, come on guys think. You breathe, so do fish. You have an immune system, so do fish. Your insides are the same as mine and pretty darn close to my pigs, I do not know enough about fish differences yet. But the periodic table AND, I am not talking about visitation rights to Pattaya, should tell you that salt equals chlorine were as all organic life forms are covered in bacteria. You have to buy some serious crap to kill it all. Then if you did, your problems only get worse! The wrong ones come Back!

Start learning the same way I did. Ask some questions. Why do some fish live at different depths in the pond? If the DO level needs to be high, how high? To oxygenate to that level over that area, how do I do that?

For God's sake, get your hands out of your wanking pockets and start understanding how little you need to spend to solve these basic issues.

Right now, I'm off to try to talk to Jim!

PS by means of edit: Lately I have adopted his intolerant when I'm half cut attitude, sorry to RBH and seriously involved players.

I will post another Tanks Setup vid, after watching this, check out the rest of the vids at the side bar, you will love it !

(note: in this vid, take notice at 5:05, look carefully at the scooter's rear wheel)

I've gone through hundreds of vids in relation to fish farming...

Enjoy and have a good day (or night)~

Bait shop is operation again. Thanks to furgus. since we fish with poles and sale in small qauntities bait is important. Nive big Red Wigglers. Three fish to worm after cut them up. 1/2 kilo in each one. Hopefully I won't kill these If things work out eventually we will sale bait around town a well a the ones we use. So time for fishing again soon. We did this a we could only get bait in the rainy season.

This is really great for small orders instead of a net full of fish. Fits for our operation.

Following on from above ... and informative post from a self-confessed aquarium enthusiast ... but on a commercial scale.

It's a work in progress as the original Thread was archived.

For filtering it depends on what you want to do with the filter...

Getting the water from the bottom reduces the leftovers so the tanks stay optically clean. As the break-up of these does need some time the needed filter construction has to start with large mesh getting gradually finer to not close the pores. At the last stage the water is free of sediments and in this area also the biofiltration takes place where nitrite is processed to nitrate.

Getting water from the top leaves the leftovers at the bottom of the tank where they can be collected and then recycled in the garden with ease. This type of filter can apart of a very thin layer with medium pores contain only fine substrate to provide surface for the bacteria processing the nitrite.

Using charcoal is only needed when you want to eliminate chemicals, so normally after some medical treatment. The disadvantage and reason not to use charcoal as default is that the binding strength of the substances to the charcoal is not equivalent to their toxicity. So whenever the charcoal is saturated a strong binding chemical binds and the charcoal releases a weaker binding for this - which might be extremely toxic. As there is no indicator for the loading of charcoal you should only use it for dedicated short time eliminations.

Salt, well that's my treatment of choice.

Whenever I have fishes with infections in my tanks they get salt up to 1/3 of seawater concentration (dosing up gradually over some hours to prevent osmotic shock). This maintaining for 3 days eliminates most infections of bacteria and fungus.

The great advantage of salt is - it's harmless for human consumption which is not the case in a lot of veterinary medicine used...

Can anyone please let me know what the 4 percentages are on the different types of feed? I have figured out the top left is percentage protein but have no idea what the others are or their importance.

[ray23]

Large pellets 16.5 % or 25% which is cat fish food. But Talapia love it. 25% is more costly. The normal feed for Talapia is 16.5 %.

I would look at Dom's topic aboput sitting up the pond. Yuo can ciut costs depending on what fish you have.

I think you will find that topic at thefron of the farming section.
