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.

Protein = 30% .Fiber = 8%

Fat = 4% .Moisture = 12%

Sometimes the information we want is right below our noses and we don't need to re-invent the wheel.

So thanks to ...

Specifically the Network of Aquaculture Centres in Asia-Pacific A really good general fish resource, with downloadable guides. what is really cool about this site is that the links are updated so that you can see the latest news and events ... for example ...

An interesting viewing ... has subtitles.

One for the Rice/fish Farmer

Published on 2 Apr 2012

Educational video done for the Ministry of Fisheries and Agriculture of Cambodia, through the NGO AIDA,
that shows not only how to become a successful fish farmer, but also find love in the countryside,

in a very informal and easy to watch way, for Cambodian fish farmers.

In Cambodia ... a relatively large tank.

Any idea on 'painting cement water' ?

They refer to it right at the end of the Video.

I wonder if you could also supply a pigment to that 'paint'?

This was the best description I could find ...

The old method of securing a patch involves simply mixing up a cement paint.

Nothing could be simpler.

You take Portland cement, add water until you have a paint consistency,

and then brush this onto the area to be patched.

Of course, the area to be patched should be ready to go.

This means that the old concrete must be free of all loose stones and grit,

free of all dust, and finally slightly damp.


Just before you are ready to install the concrete patching compound,

you simply paint a thin coat of the cement paint onto the clean, solid, damp old concrete.

The patching compound is then added.

The result, as long as you finish it, cure it, and protect it, will be a long lasting patch.

Cambodia : USAID Aquaculture training video (english)

Great Video in some parts ... thanks for sharing.

I had to laugh when the two friends met each other in the rural countryside on their bikes and both were wearing Helmets!

The Video says to release 1 Tilapia per m2 ... because they reproduce quickly.

All the Farmers I know only raise mono-sex fish because they don't wish for a 2nd generation competing for the resources of the pond.

Quick newbie question.

I m just stared a small cement tank pla duk lard sia farming with gf and been reeding most information here om the forum and got many good ideas from here. But I see in many threds that it should be good to put in a few handfulls of salt with every water change. But what kind of salt do you use? I asked in shop where I buy fish food but she said she dont know anything about putting salt in water...Just add EM she said.

The pepole here in village dont put anything in water, no salt, no em...

But I think should be both EM and salt, right? Just any kind of salt? Same salt like I use to cook food? Like most people I have problem with fish water smelling bad.

I dont use any filter or pump...

Very thankfull for all information I find here on forum :) Sorry for very poor english skills, not native english speaker...

GL with farming to ALL

If, per chance you don't get an answer here in a couple of days (it's not my area of knowledge) send a private message to either RedBullHorn or/and IssanAussie as that is a specialist area for them.

By my knowledge activated EM 1 is used to eliminate ammonia (water smelling bad)
Salt (kitchen salt) is used to bring your nitrate level down
But like David say ask RedBullHorn or/and IssanAussie they are high skilled professional fishfarmers smile.png

AES Mini Fish Farm Instructional Video

Not for everyone, but interesting to watch and see this University Guys take on it.

No idea what it's worth to buy.

Would have interested to know more about the vege table he set up there is it seemed to have an element of Aquaponics to the set-up in the end.

Ok, I will try with the EM and kitchen salt. Also I think my fishtank are to smal for the amount of fish that I have so will build another one. Thanks for your help :)

Maybe your overfeeding your fish this can cause high ammonia and water smelling bad

How much should I feed them? I have 500 fish about 1 mount old in small cement tank. Feed morning about 08.00 and evening about 18.00. Somebody tell me feed the fish slowly and see when the dont eat quickly as in begining thay are full and I should stop give them food.

When I change water everything is good for about 2-3 days and then water start to smell alot and fish will eat little or not eat at all. Also all fish heads are up at the surface all the time. When water is good fish swim aroud, but when water is bad only stay floting at the surface.

Also about the sunshine, do pla duk like much sunshine or little sunshine? Somebody tell me water smell bad because to much sunshine, but then I read pla duk need sunshine to grow big?

Also when buildning new fish tank, is it better to build a long but not so deep thank or should it be smaler but deeper or how shuold it be??

As you see I have alot of question and are really confused. I am very beginner and dont know anything about fishfarm, but want to learn and hoping to get advice from more experiend farmer.

Thanks

mengfarmer, The salt is land salt or sea salt. Refinery process you get table salt, the type use for cooking...

We call it Black salt (เกลือดำ) not because it is black in colour but because it look light dirty brown and it is chucky rock size that have not been refine for table salt. Here's some pictures of cycloneJ's salt farm.

Salt is the solution for controlling Nitrite not the harmless Nitrate. Table salt is alright, just that it is more expensive.

Feed until satiation (until they're full), over feeding not recommended. Will foul up water easily.

Partially shade your tank with a roof that provide 20% sunlight that will shine on the water at time between 3-5pm, when i mentioned shade, i meant a 1m high roof from the hight of your tank preferably made of grass or leaves panels. Not some made-shift cardboard, plywood or old used roof tiles covering on top of the tank, heat builds up inside with not ventilation like an oven.

It is the Water that needs the sunshine not the pla duk but if water temperate is too high and your fishes will be stress. Sunshine helps in pond water anaerobic cycle.

EM is meant for controlling bad bacteria.

Thank you for your quick answer :) I have some follow up question, hope you dont mind!

My GF have something she calls homemade salt that she use for cooking, looks like dirty seasalt and taste like salt. You think that is ok to use for pla duk?

About EM. Should EM go in everyday or only when change water? Lady in shop say EM work only 7 days efter opening bottle so have to use it all before that right?

I read somewhere that you talk about grade A, B and C food? What is that? Is that the size of food? I use "fish first" food, is that ok?

Once again thank you for help. I not want and will never be professional fish farmer, but maybe with you advice I can be ok hobby farmer :)

Cheers

1. Yes that salt is usable. Do your best to source for sales-by-bulk salt distributor in your province, buy by sack is more economic.

2. You change water every 3-5 days, so lets not worry about 7 days. Please ask David48 to provide links to EM threads.( burp.gif brain not working now. )

3. Fish First from LabInter is B grade, Omeg from Betagro is A Grade (7 series) and Betagro 8 series is Premium Grade. Betagro Master is C grade. The Grade different is in the quality of ingredient use thus decides the Feed Conversion Ratio (FCR).

Edit: Thanks sjefrie for the EM links. thumbsup.gif
