Good evening all. Please, I seek answers to few questions. How do I calculate the quantity of water that a pond will contain?

How can I calculate/estimate the number of fish a pond can contain to table size?

Thanks in advance for your responses

Learn to culture live food - Daphnia - for use in your hatchery.

It's an excellent food for them. I have tested it's efficacy in a 1000litre tank known as IBC. After fellows said I couldn't hatch eggs in such tank filled with water unless the tank is cut in half as some Folks are using. Well, for me I like research. I simply waited for the usual two days after hatching...not sure if the larvae survived cos I couldn't see down the tank as the water wasn't very clear then as I actually used water that has been there for nearly a week plus I added CaCO3 and didn't wait for it to settle, mind you the tank was plain outside in the worst conditions and the tank didn't get any inflow till the 20th hr after fertilization, as opposed to a regular clarias hatchery. I did put it on flow-thru though from the 20th hr onwards and only stopped inflow when I fed them daphnia. Now feeding was to commence from day 3..I pushed Arte something aside mind you I had collected some Daphnia and cultured for four days they multiplied as expected and as I planned, I simply connected a transparent tube (it was a drip set with the flow regulator..very ingenious. lols) to the daphnia container and let the thing run down into the very bottom of the tank full of water for good 4days all the while stopping the flow, resume flow thru, feed the daphnia and allow them multiply a little more then open the regulator again...(you can call it Daphnia population control). I wasn't seeing any larvae yet after 3days from commencing exogenous feeding yet I kept pumping in daphnia. By the 4th day I was running out of Daphnia and at about 8 pm I had a feeling and went to the tank with my phone flashlight and behold! Swarms of black fries wriggling and clustered together on all four corners of the tank tho shy cos of the light and some went back down. I had a good sleep and By morning I confidently removed the covering I placed to shed off sunlight and a few hrs later they were up and everywhere looking for more Daphnia but there wasn't more...... mission accomplished! end of proposed research! I sent photo of the swarm to one of my farmer friend and course mate.

Now how to culture daphnia.

Firstly, you need to locate a pool of water around you...if you leave in areas without tarred road or maybe the drainage (gutter that holds water for some days after rainfall - not the unsightly ones) if you leave in the city.

Secondly, about one or two days after a moderate rainfall observe the pool or drainage water surface in the evening or very early morning there maybe some reddish little things moving in clusters in the water... especially if the water is a bit muddy looking and undisturbed...(and no chemicals or bad oil is entering the water)... Yeah!!! That's Daphnia and maybe other things I don't know yet.

Third. Collection time!
Gently Scoop them up with their water as much as you can.. if it looks like it finished come back in the evening or next morning and check again.

Fourth. Inoculation and set up.
Quite simple but technical. If you want to maintain big volume cultures you will need aeration. Otherwise dump them into a shallow green water.. about one foot deep..they love the algae..that's what they'd be busy harvesting and other things I don't know too when you see them in the water surface otherwise they'll stay down. (oh you should have prepared some good hatchery quality water and fertilized it to develop algae bloom before going daphnia fishing).
Oh wait! You could also keep them in clear shallow water and maintain flow thru but that will require a bit of construction with a certain net mesh size so you don't loose the smaller guys which you larvae will prefer to start dining on... people don't usually like this idea o.
Oh wait again! You could maintain small cultures in static clear water in about 20litre buckets starting with water at half the bucket and adding some fresh water daily to sustain oxygen and also make room for baby daphnia. You have to keep this from direct sunlight and heat. Then, when the buckets is near full you simply split and resume daily water addition... that's smart right? Before you get carried away remember to inoculate the bucket with just few daphnia to avoid initial overpopulation and also you get to know if they've survived and are multiplying or not...that's the fun part...watching them increase in numbers. The volume you chose to use for inoculation will depend on the quantity you caught when you went daphnia fishing. Lols! We should have put this method first.

Fifth. Care.
Feeding time. After inoculation (static clear water buckets) you might want to allow them adjust to their new environment. Usually this takes about 6hrs or more...for me I just left them for a day to let the muddy water settle so I could see how much was in there and for them to eat off whatever food that came with the water and get quite hungry.
What did I feed them You're itching to know... Yeast. Yes Yeast. Baker's Yeast. It's in the market. That woman that sells baking stuff is waiting for you now. Mind you I used granulated ones...like milkish coloured sand grains inside the tin when you open it. There may be other options to feed daphnia but yeast worked pretty well for me.
How do you feed them Simply dissolve a few grains in warm water(as warm as you can drink without fear of hurting yourself or even less warm... the thing simply melts when the warm water touches it... you need about a teaspoon of water to dissolve the yeast and then add up some hatchery water to bring the solution to cooler temperature so you don't boil the daphnia.
How much quantity to feed You just need enough to slightly cloud up the water.... not too cloudy tho otherwise they die of oxygen shortage...so a few drops at a time and watch the solution diffuse throughout the water and the feeding frenzy begins!- this part will be interesting if you have them in transparent container. Preferably feed little quantities several times a day so you don't risk crashing your daphnia culture due to oxygen shortage....
Alternatively, you may slowly drop the grains on the water surface... they float if careful placed then they absorb water and start sinking forming a cloud trail while sinking... the trail attracts onlookers/onfeeders...
REMEMBER!!! the yeast too are living things... FUNGI as a matter of fact and you may want to wash your hand after handling...I don't know what may happen if you don't wash, ask your microbiologist neighbor. As soon as feeding starts, some of your daphnia will grow bigger, visibly bigger.. they've got eggs, they lay the eggs and you know what happens next. As they multiply keep splitting and feeding and splitting...I liked this part. If you have extra containers you may want to gently transfer older cultures to clean containers and wash of debris... hygiene is necessary here too if you want to maintain them for a long time also you don't want debris and other stuff I don't know in your larvae tank... adding yeast to my containers caused small algal growths on container walls as the containers received some good sunlight before noon.

If you're using green water method then your responsibility is to maintain the algae...but this is not very interesting as you'll hardly know what's going on in there with the daphnia. Besides, i feel you'd still need to add little yeasts as well to supplement feeding... I am not sure daphnias are strictly vegetarians. I feel This method may also require a way of clearing out the algae before feeding the daphnia to your larvae as am not sure if you want algae in your hatchery water at this stage.... I didn't do it this way so you may try this method and tell us how it went... I've noticed one research opens the way to another.

Feeding your Larvae.
I did not pour the daphnia and activated yeast into the tank - (oh I forgot to mention earlier... when you add warm water to the dried yeast I was told they'd become activated... whatever that meant was not my concern then, my concern was to dissolve them). I simply fed the daphnia in the morning and allowed them to consume every yeast and by evening the water was crystal clear except for the daphnia in it hunting for yeast then I connected my tube opened the regulator to slowly siphon them into the larvae tank till the next day and left -those larvae didn't get the best care, it wasn't intentional tho but I had other things to do besides it was just research and I wasn't very serious with it again after I confirmed the larvae were fine. You may also scoop them with a cup if you have the time.... Remember to add hatchery water to the daphnia container you wish to feed to your larvae to taper the water so it is near same as the water in your larvae tank...you don't want to shock your larvae with rapid water quality change...your larvae won't like you very much. Also, adding water will increase the volume so most of the daphnia will go thru the tube before the water level reduces (if you're using what I now wish to call Slow Siphon Method - SSM) and so you don't have to wait on it. The quantity you feed your larvae is up to you. Fear not! The daphnia will not pollute your water if they remain uneaten they will simply be swimming around- tho I doubt Clarias larvae will allow that.


Okay, it's time for me to say clearly that your results may differ from mine but my intention here is to help you and others culture there own live feed for fish hatchery use. Live feed is the best for starting your fish larvae and afterwards as they grow bigger you will have to switch to compounded dry diets. Suffix it to say that Artemia is a good option too if you got a good quality brand and you're skilled at using it.

What point did I miss pls?

I appreciate you for starting up this wonderful trend. It has really build up my confidence in taking actions to start up fish farm. God reward you bountifully.

I also appreciate every one in this forum who have honestly and selflessly unleash great insight to fish farming. Also those that asked questions, I have equally learnt from you. God bless you all real good and increase you on all sides.

In as much as I read agriculture in school and love fish farming, taking up the bold step to start up was a major
Challenge to me because so many farmers are withholding most practicle knowledge.

Having read in between the lines from page 1- 486, I will like to say it is worth all the time, sleepless nights and patient. I have learnt a lot and also willing to learnt more from the farmers in Port Harcourt.

hello farmers, can fish feeds only on maggots from 8 weeks till table size?

aquatic1:
Get a big basin and pack them inside before washing the pond, the quantity u stock in each pond is not much, and it will create enough space for them to grow.

can fish feeds only on maggots from 8 weeks till table size?

excelsiorfarm:
by your measurement your tanks should contain 9000 litres and 6300 litres of water respectively, so from this calculation, you can easily get your answers, but adhere to the advise given previously

please sir, how many fishes can store in this type of tank

well you start with imported feeds of different sizes depending on their growth. sizes are 1mm 1.8mm/2mm 3.5mm 4.5mm 6mm till growth out .
imported feeds like skretting is good but you can start the use of local feeds after sometime.
well quantity depends on the number of fish and their sizes but do not over feed fingerlings
if you are a starter its better you starts with the juveniles.
all i said above are just my opinions others have their ways too so its better to learn from more than one person.
